Minamata ( 水俣市 , Minamata-shi ) is a city located in Kumamoto Prefecture , Japan . It is on the west coast of Kyūshū and faces Amakusa islands. Minamata was established as a village in 1889, re-designated as a town in 1912 and grew into a city in 1949. As of March 2017, the city has an estimated population of 25,310 and a population density of 160 persons per km. The total area is 162.88 km.
150-536: Minamata is known due to Minamata disease , a neurological disorder caused by mercury poisoning. The disease was discovered in 1956. A local chemical plant was blamed for causing the disease by emitting untreated wastewater into Minamata Bay. Lately, Minamata has focused on becoming a model environmental city. In 1999, the city obtained the ISO 14001 certification for Environmental Management. In 2001, Minamata became an official Japanese Eco-town. In 2004 and 2005, Minamata won
300-539: A WHO Collaborating Centre for Studies on the Health Effects of Mercury Compounds. The Institute seeks to improve medical treatment of Minamata disease patients and conducts research on mercury compounds and their impact on organisms as well as potential detoxification mechanisms. In April, 2008 the Institute invented a method for adsorbing gaseous mercury in order to prevent air pollution and enable recycling of
450-494: A public health emergency of international concern, marking the second such declaration in the last two years due to the virus's transmission. The WHO's Constitution states that its objective "is the attainment by all people of the highest possible level of health". The WHO fulfils this objective through its functions as defined in its Constitution: As of 2012 , the WHO has defined its role in public health as follows: Since
600-543: A Nature-oriented Ecological Town, Development of The City for Environmental Learning. This target area has three main goals: Since August 1993, in order to promote recyclable household garbage through sorting, the residents of Minamata City have planned (before any other city in Japan) a detailed garbage classification system; garbage was divided into 21 categories in the fiscal year 1999, and has now reached 24 categories. The City has set up 300 garbage collection stations around
750-599: A Trial Research Group, which included law professors, medical researchers (including Harada), sociologists and even Michiko Ishimure to provide useful material to the lawyers to improve their legal arguments. Their report, Corporate Responsibility for Minamata Disease: Chisso's Illegal Acts , published in August 1970, formed the basis of the ultimately successful lawsuit. The trial lasted almost four years. The litigation group's lawyers sought to prove Chisso's corporate negligence . Three main legal points had to be overcome to win
900-727: A capacity of 100.000 kilolitres/year capacity. The facility will run for the remainder of 2012 to consider the feasibility of the process. The second goal is to have safe and reliable production in Agriculture, Forestry and Fisheries. The emphasis in this project is on local food production to reduce food mileage. Local agriculture produces mostly rice, mandarins and local salad onions. After the Minamata disease scandal local farmers wanted to show that their products were safe, so they changed their way of production by: not using pesticides anymore, use 70% less fertilizer and instead started using
1050-427: A catalyst. Starting in August 1951, the co-catalyst was changed from manganese dioxide to ferric sulfide. A side reaction of this catalytic cycle led to the production of a significant amount (about 5% of the outflow ) of the organic mercury compound methylmercury . As a result of the catalyst change, this highly toxic compound was released into Minamata Bay regularly between 1951 and 1968, when this production method
1200-542: A chemical factory in Minamata , Kumamoto Prefecture , located on the west coast of the southern island of Kyūshū . Initially producing fertilisers, the factory followed the nationwide expansion of Japan's chemical industry, branching out into production of acetylene , acetaldehyde , acetic acid , vinyl chloride , and octanol , among others. The Minamata factory became the most advanced in all of Japan, both before and after World War II . The waste products resulting from
1350-451: A complete victory for the patients of the litigation group: The defendant's factory was a leading chemical plant with the most advanced technology and ... should have assured the safety of its wastewater. The defendant could have prevented the occurrence of Minamata disease or at least have kept it at a minimum. We cannot find that the defendant took any of the precautionary measures called for in this situation whatsoever. The presumption that
1500-502: A convention concerning the bubonic plague was signed by sixteen of the nineteen states attending the Venice conference. While Denmark , Sweden-Norway , and the US did not sign this convention, it was unanimously agreed that the work of the prior conferences should be codified for implementation. Subsequent conferences, from 1902 until the final one in 1938, widened the diseases of concern for
1650-602: A diagnosis of organic mercury poisoning. Chisso did not reveal these significant results to the investigators and ordered Hosokawa to stop his research. In an attempt to undermine Kumadai researchers' organic mercury theory, Chisso and other parties with a vested interest that the factory remain open (including the Ministry of International Trade and Industry and the Japan Chemical Industry Association) funded research into alternative causes of
SECTION 10
#17327827167151800-778: A forum for scientific or policy discussions related to health. Its official publication, the World Health Report , provides assessments of worldwide health topics. The WHO has played a leading role in several public health achievements, most notably the eradication of smallpox , the eradication of polio , and the development of an Ebola vaccine . Its current priorities include communicable diseases , such as HIV/AIDS , Ebola , malaria and tuberculosis ; non-communicable diseases such as heart disease and cancer ; healthy diet , nutrition, and food security ; occupational health ; and substance abuse . The agency advocates for universal health care coverage, engagement with
1950-480: A glass of water supposedly treated through the Cyclator to demonstrate that it was safe. In fact, the wastewater from the factory, which the company knew still contained mercury and led to Minamata disease when fed to cats, was not being treated through the Cyclator at the time. Testimony at a later Niigata Minamata disease trial proved that Chisso knew the Cyclator to be completely ineffective: "The purification tank
2100-488: A heavy metal as the causal substance, the wastewater from the Chisso factory was immediately suspected as the origin. The company's own tests revealed that its wastewater contained many heavy metals in concentrations sufficiently high to bring about serious environmental degradation , including lead , mercury , manganese , arsenic , thallium , and copper , plus the chalcogen selenium . Identifying which particular poison
2250-516: A joint survey in late 1960 and early 1961 into the level of mercury in the hair of people living around the Shiranui Sea. The results confirmed that organic mercury had spread all around the inland sea and that people were still being poisoned by contaminated fish. Hundreds of people were discovered to have levels greater than 50 ppm of mercury in their hair, the level at which people are likely to experience nerve damage. The highest result recorded
2400-588: A long time an abnormally high frequency of cerebral palsy and other infantile disorders in the Minamata area. In 1961, a number of medical professionals, including Masazumi Harada (later to be honored by the United Nations for his body of work on Minamata disease), set about re-examining children diagnosed with cerebral palsy. The symptoms of the children closely mirrored those of adult Minamata disease patients, but many of their mothers did not exhibit symptoms. The fact that these children had been born after
2550-560: A one-off ¥320,000 ($ 2935) payment. On 21 October 1959, Chisso was ordered by the Ministry of International Trade and Industry to switch back its wastewater drainage from the Minamata River to Hyakken Harbour and to speed up the installation of wastewater treatment systems at the factory. Chisso installed a Cyclator purification system on 19 December 1959, and opened it with a special ceremony. Chisso's president Kiichi Yoshioka drank
2700-424: A partial ban on the sale of fish caught in the heavily polluted Minamata Bay – but not an all-out ban, which would have legally obliged it to compensate the fishermen. The fishing cooperative protested against Chisso and angrily forced their way into the factory on 6 August and 12 August, demanding compensation. A committee was set up by Minamata Mayor Todomu Nakamura to mediate between the two sides, but this committee
2850-677: A policy to amend relations between victims of the Minamata Disease and the other citizens and to give an end to prevailing social divisions. On 1 April 1992 the first Memorial Service for the Victims of Minamata Disease was organized and has taken place annually ever since. Moreover, the Minamata Disease Municipal Museum was founded in January 1993 in order to collect, preserve and pass on information about
3000-682: A re-examination of that done in Minamata and the decision of Niigata patients to sue the polluting company allowed the same response to be considered in Minamata. Masazumi Harada has said that, "It may sound strange, but if this second Minamata disease had not broken out, the medical and social progress achieved by now in Kumamoto... would have been impossible." Around this time, two other pollution-related diseases were also grabbing headlines in Japan. People with Yokkaichi asthma and itai-itai disease were forming citizens' groups and filed lawsuits against
3150-540: A resolution on disability prevention and rehabilitation , with a focus on community-driven care. 1977 and 1978: The first list of essential medicines was drawn up, and a year later the ambitious goal of " Health For All " was declared. 1986: The WHO began its global programme on HIV/AIDS . Two years later preventing discrimination against patients was attended to and in 1996 the Joint United Nations Programme on HIV/AIDS (UNAIDS)
SECTION 20
#17327827167153300-429: A resolution passed on the subject, Alger Hiss , the secretary general of the conference, recommended using a declaration to establish such an organization. Sze and other delegates lobbied and a declaration passed calling for an international conference on health. The use of the word "world", rather than "international", emphasized the truly global nature of what the organization was seeking to achieve. The constitution of
3450-751: A result, in December 1997, 16 women's groups, which have great interest in waste reduction, met together and organized the "Women's Liaison Conference on Waste Garbage" with the slogan of "Let's reduce the increasing garbage from each household!" They actively encourage residents not to bring home items that are not absolutely required which may result in waste, to repair broken items and to buy recycled products when possible. Major activities of "Women's Liaison Meeting for Reducing Waste" are: The municipal office of Minamata City obtained ISO 14001, international standard for environmental management, in February 1999. Under
3600-508: A series of conferences that took place until 1938, about 87 years. The first conference, in Paris, was almost solely concerned with cholera , which would remain the disease of major concern for the ISC for most of the 19th century. With the cause , origin, and communicability of many epidemic diseases still uncertain and a matter of scientific argument, international agreement on appropriate measures
3750-487: A significant impact on the actions of the company or the coverage of Minamata in the Japanese media. Despite the almost universal assumption to the contrary, the wastewater treatment facilities installed in December 1959 had no effect on the level of organic mercury being released into the Shiranui Sea. The pollution and the disease it caused continued to spread. The Kumamoto and Kagoshima prefectural governments conducted
3900-529: A special fertilizer from Chisso. In the 2011 environmental report the local production was stable for the last 10 years and the advice was to promote local production. Fishing was not possible from 1970 till 1997, because the bay was closed with a net to prevent the catching of contaminated fish. During this period fishers were compensated by the local government. When the nets were removed sardine catching started to flourish and there now are full-time and part-time fishers, who combine fishing with other jobs. Finally
4050-413: A specific field of production, which is quite unique. This system guarantees that certain products are safe to use. In 2000, Minamata City obtained ISO14001 certification to reduce environmental burdens associated with service businesses for citizens. The city drew up a version of ISO, for various service businesses for citizens, such as an office, home, preschool and hotel. The city has the authority to do
4200-512: A system for certifying craftsmen who attach much importance to the environment in their production activities. This is called the Environment Master System, and commenced in fiscal 1998, before any other city in Japan. This is to improve the status and consciousness of craftsman and promote the creation of safe and sound commodities in consideration of environment and health, reflecting their experience with Minamata disease. In

Signs and symptoms include ataxia , numbness in the hands and feet, general muscle weakness , loss of peripheral vision , and damage to hearing and speech . In extreme cases, insanity , paralysis , coma , and death follow within weeks of the onset of symptoms. A congenital form of the disease affects fetuses in the womb, causing microcephaly, extensive cerebral damage, and symptoms similar to those seen in cerebral palsy . Minamata disease
4500-521: Is a poisoning disease that affects mainly the central nervous system and is caused by the consumption of large quantities of fish and shellfish living in Minamata Bay and its surroundings, the major causative agent being some sort of organic mercury compound. During the Kumadai investigation, the causal substance had been identified as a heavy metal and it was widely presumed that the Chisso factory
4650-481: Is globally accepted by policymakers and resulted in the UNEP Minamata Convention. The first patient with previously unseen neurological symptoms was reported in Minamata in 1956. In 1959, a researcher from Kumamoto University suspected that an organomercury compound could be the cause. However, paths of transformation of inorganic to organic mercury were unknown or uncertain at that time and so

Minamata disease patients last appeared in 1960, and the outbreak has ended. This is presumed to be because consumption of fish and shellfish from Minamata Bay was banned in the fall of 1957, and the fact that the factory had waste-treatment facilities in place from January 1960. The conclusion contained many factual errors: eating fish and shellfish from other areas of

JNC Corp is one such bioethanol plant that was established in early 2012 that will produce 100,000 kiloliters/ year of bioethanol from bamboo. In this target area, Minamata eco-town committed itself to the four following goals: In 1998, Minamata City set up an original certification system to support producers, which is called the "Environmental Meister Programme". The "Environmental Meister Programme" certification focuses on environment and health, but not on

Between 1990 and 2010, WHO's help has contributed to a 40% decline in the number of deaths from tuberculosis, and since 2005, over 46 million people have been treated and an estimated 7 million lives saved through practices advocated by WHO. These include engaging national governments and their financing, early diagnosis, standardising treatment, monitoring of

But in the environmental report of the city from 2011. It is not stated that biomass energy is used and most of the energy is purchased (48%) or made from oil (44%). In January 2012 a test facility to make Bio-ethanol from bamboo was opened with
5550-468: The Edo period . The Chisso factory first started acetaldehyde production in 1932, with 210 tons that year. In 1951, production had jumped to 6,000 tons and eventually peaked at 45,245 tons in 1960. The factory's output historically amounted to between a quarter and a third of Japan's total acetaldehyde production. The chemical reaction used to produce the acetaldehyde employed mercury sulfate as
5700-490: The Japanese Diet became remembered as the "Pollution Diet," as the Japanese government took action under the pressure of civil society movements provoked by Minamata disease as well as other two major environmental catastrophes - Yokkaichi Asthma and Itai-itai disease. Fourteen new environmental laws were passed in a single session, giving Japan what at the time were the most stringent environmental protection laws in

Brock Chisholm was appointed director-general of the WHO, having served as executive secretary and a founding member during the planning stages, while Andrija Štampar was the assembly's first president. Its first priorities were to control the spread of malaria , tuberculosis and sexually transmitted infections , and to improve maternal and child health , nutrition and environmental hygiene. Its first legislative act
6600-600: The litigation group (who decided to sue the company). That summer, Chisso sent gifts to the families who opted for arbitration rather than litigation. An arbitration committee was duly set up by the Ministry of Health and Welfare on 25 April, but it took almost a year to draw up a draft compensation plan. A newspaper leak in March 1970 revealed that the committee would ask Chisso to pay only ¥2 million ($ 5,600) for dead patients and ¥140,000 to ¥200,000 ($ 390 to $ 560) per year to surviving patients. The arbitration group were dismayed by
6750-692: The 1959 agreement. Minamata disease broke out again in 1965, this time along the banks of the Agano River in Niigata Prefecture . The polluting factory (owned by Showa Denko ) employed a chemical process using a mercury catalyst very similar to that used by Chisso in Minamata. As in Minamata, from the autumn of 1964 to the spring of 1965, cats living along the banks of the Agano River had been seen to go mad and die. Before long, patients appeared with identical symptoms to patients living on

From 1932 to 1968, the chemical company Chisso discharged effluent containing methyl mercury from their plant in Minamata. Methyl mercury contaminated Minamata Bay and accumulated in fish, which were then consumed by the local population. In 1968

There is also a program about aquatic environment, a program about pollution in rivers and several programs regarding recycling. According to Japanese census data, this is the population of Minamata in recent years. Minamata disease Minamata disease ( Japanese : 水俣病 , Hepburn : Minamata-byō )
8100-459: The Minamata population in general. In patients, the maximum mercury level recorded was 705 parts per million (ppm), indicating very heavy exposure and in nonsymptomatic Minamata residents, the level was 191 ppm. This compared to an average level of 4 ppm for people living outside the Minamata area. On 12 November 1959, the Ministry of Health and Welfare 's Minamata Food Poisoning Subcommittee published its results: Minamata disease
8250-567: The Shiranui Sea, and the outbreak was made public on 12 June 1965. Researchers from the Kumamoto University Research Group and Hajime Hosokawa (who had retired from Chisso in 1962) used their experience from Minamata and applied it to the Niigata outbreak. In September 1966, a report was issued proving Showa Denko's pollution to be the cause of this second Minamata disease outbreak. Unlike the patients in Minamata,
8400-509: The Shiranui Sea, not just Minamata Bay, could cause the disease; eating small amounts, as well as large amounts of contaminated fish over a long time also produced symptoms; the outbreak had not, in fact, ended in 1960 nor had mercury-removing wastewater facilities been installed in January 1960. Nevertheless, the government announcement brought a feeling of relief to a great many victims and their families. Many felt vindicated in their long struggle to force Chisso to accept responsibility for causing

During the 1970s, WHO had dropped its commitment to a global malaria eradication campaign as too ambitious, it retained a strong commitment to malaria control. WHO's Global Malaria Programme works to keep track of malaria cases, and future problems in malaria control schemes. As of 2012,

The extensive research by Kumadai and the government's conclusion meant that this point was proved quite easily. Second, they needed to show that Chisso could and should have anticipated the effect of its wastewater and taken steps to prevent the tragedy (i.e.,

The staple food of victims was invariably fish and shellfish from Minamata Bay. The cats in the local area, which tended to eat scraps from the family table, had died with symptoms similar to those now discovered in humans. This led
10950-513: The change of route of wastewater output in 1958, pollution had spread up and down the Shiranui Sea, damaging fisheries there as well. Emboldened by the success of the small Minamata cooperative, the Kumamoto Prefectural Alliance of Fishing Cooperatives also decided to seek compensation from Chisso. On 17 October, 1,500 fishermen from the alliance descended on the factory to demand negotiations. When this produced no results,
11100-402: The committee uncovered surprising anecdotal evidence of the strange behaviour of cats and other wildlife in the areas surrounding patients' homes. From around 1950 onward, cats had been seen to have convulsions, go mad, and die. Locals called it the "cat dancing disease", owing to their erratic movement. Crows had fallen from the sky, seaweed no longer grew on the sea bed, and fish floated dead on
11250-627: The continuing effects of nuclear disasters in Chernobyl and Fukushima . They believe WHO must regain what they see as independence. Independent WHO held a weekly vigil from 2007 to 2017 in front of WHO headquarters. However, as pointed out by Foreman in clause 2 it states: In particular, and in accordance with the Constitution of the World Health Organization and the Statute of the International Atomic Energy Agency and its agreement with
11400-439: The council has always been under immense pressure to reject claimants and minimise the financial burden placed on Chisso. Rather than being a council of medical recognition, the decisions of the council were always affected by the economic and political factors surrounding Minamata and the Chisso corporation. Furthermore, compensation of the victims led to continued strife in the community, including unfounded accusations that some of
11550-584: The day of the signing, the Minamata Citizens' Council held a protest outside the Chisso factory gates. One of the Chisso trade unions held an eight-hour strike in protest at the poor treatment of the arbitration group by their own company. The litigation group, representing 41 certified patients (17 already deceased) in 28 families, submitted their suit against Chisso in the Kumamoto District Court on 14 June 1969. The leader of
11700-477: The defendant had been negligent from beginning to end in discharging wastewater from its acetaldehyde plant is amply supported. The defendant cannot escape liability for negligence. The "sympathy money" agreement was found to be invalid and Chisso was ordered to make one-time payments of ¥18 million ($ 66,000) for each deceased patient and from ¥16 million to ¥18 million ($ 59,000 to $ 66,000) for each surviving patient. The total compensation of ¥937 million ($ 3.4 million)
11850-451: The discharge of poisonous effluent was ceased due to discontinuation of acetaldehyde production at the Chisso factory. However, the sea sediment as well as fish remained contaminated and so measures were taken to counteract the effects. In 1975, the bay was fenced by fishing nets. A sludge dredging project was initiated in 1977 and continued until 1990. During the project, 784,000m of sludge
12000-405: The discovery of the disease (and four months after Chisso had stopped production of acetaldehyde using its mercury catalyst) – the Japanese government issued an official conclusion as to the cause of Minamata disease: Minamata disease is a disease of the central nervous system, a poisoning caused by long-term consumption, in large amounts, of fish and shellfish from Minamata Bay. The causative agent
12150-511: The disease and expressed thanks that their plight had been recognised by their social superiors. The struggle now focused on to what extent the victims should be compensated. In light of the government announcement, the patients of the Mutual Aid Society decided to ask for a new compensation agreement with Chisso and submitted the demand on 6 October. Chisso replied that it was unable to judge what would be fair compensation and asked
12300-563: The disease and related issues. Apart from exhibitions, the Museum offers story-telling sessions by Minamata disease patients. Additional Minamata Disease archives were opened in 2001. In respect of envisaged sustainable development, the municipal government addressed environmental challenges along the social ones; A Declaration of the Construction of Eco-City Model was launched in 1992. Subsequently, waste separation by citizens became one of
12450-484: The disease to be contagious, and many local people were fiercely loyal to Chisso, depending on the company for their livelihoods. In this atmosphere, those affected were reluctant to come forward and seek certification. Despite these factors, over 17,000 people have applied to the council for certification. Also, in recognising an applicant as having Minamata disease, the certification council qualified that patient to receive financial compensation from Chisso. For that reason,
12600-480: The disease, other than its own waste. Polluting wastewater had damaged the fisheries around Minamata ever since the opening of the Chisso factory in 1908. The Minamata Fishing Cooperative had managed to win small payments of "sympathy money" from the company in 1926 and again in 1943, but after the outbreak of Minamata disease, the fishing situation was becoming critical. Fishing catches had declined by 91% between 1953 and 1957. The Kumamoto prefectural government issued
12750-479: The downside of Japan's post-war rapid economic development to the global public. In 1978, the National Institute for Minamata Disease was established in Minamata. It consists of four departments: The Department of Basic Medical Science, The Department of Clinical Medicine, The Department of Epidemiology and The Department of International Affairs and Environmental Sciences. In 1986, The Institute became
12900-592: The dreadfulness of environmental pollution and because of this, they can now produce truly safe and harmless products. Before the establishment of the master system, Minamata products were simply products produced with confidence by people who were particularly concerned about the environment. In the future, however, they will be traded as brand products produced by the renowned environmental masters of Minamata City. There are six qualification criteria to become an environmental master: Minamata tries to develop environmentally friendly industries with three goals. The first topic
13050-431: The effluent from Chisso was not identified as the sought source. It took 9 more years until the government officially acknowledged mercury-containing effluent from local acetaldehyde chemical plants to be the cause of Minamata disease. Since then, victims of Minamata disease have been compensated by Chisso and both local and national governments, due to the lawsuits won and official relief programs. The 1970 session of
13200-435: The environment in every part of their processes, including materials selection, production, processing, selling, and disposal of waste. "Products produced by environmental masters" mean safe and sound products certified by the municipal office. For some time in the past, Minamata-made products were not favorably accepted on the market due to the bad image of the city. Nonetheless, people in Minamata have learned through experience
13350-450: The environment. The aim of this project is to make the actions as practical as possible, so children can easily implement that in their everyday life. The Japan International Cooperation Agency (JICA) established a training program in which participants can learn the lessons of Minamata. At the end of the program, the participants are expected to achieve the following: In Minamata itself, there are several environmental learning programs. At
13500-494: The factory was producing and by what methods. The Chisso factory's hospital director, Hajime Hosokawa , established a laboratory in the research division of the facility to carry out his own experiments into Minamata disease in July 1959. Food to which factory wastewater had been added was fed to healthy cats. Seventy-eight days into the experiment, cat 400 exhibited symptoms of Minamata disease and pathological examinations confirmed
13650-601: The fiftieth anniversary of WHO's founding. He, did, however, accept that more had to be done to assist maternal health and that progress in this area had been slow. 2000: The Stop TB Partnership was created along with the UN's formulation of the Millennium Development Goals . 2001: The measles initiative was formed, and credited with reducing global deaths from the disease by 68% by 2007. 2002: The Global Fund to Fight AIDS, Tuberculosis and Malaria
13800-416: The first year, fiscal 1998, nine craftsmen engaged in the activities of paper making, and the production of tea leaves, bread, tangerine oranges, vegetables, rice or eggs were certified. In fiscal 1999, five craftsmen including a tatami-maker were additionally certified, making the current total of certified environmental masters fourteen. All of them produce products with confidence and pay careful attention to
13950-479: The focus of the investigation centered on mercury. In February 1959, the mercury distribution in Minamata Bay was investigated. The results shocked the researchers involved. Large quantities of mercury were detected in fish, shellfish, and sludge from the bay. The highest concentrations centred around the Chisso factory wastewater canal in Hyakken Harbour and decreased going out to sea, clearly identifying
14100-449: The global smallpox eradication campaign by contributing $ 2.4 million annually to the effort and adopted a new disease surveillance method, at a time when 2 million people were dying from smallpox per year. The initial problem the WHO team faced was inadequate reporting of smallpox cases. WHO established a network of consultants who assisted countries in setting up surveillance and containment activities. The WHO also helped contain
14250-564: The group, Eizō Watanabe (a former leader of the Mutual Aid Society), declared, "Today, and from this day forth, we are fighting against the power of the state." Those who decided to sue the company came under fierce pressure to drop their lawsuits. One woman was visited personally by a Chisso executive and harassed by her neighbours. She was blackballed by the community, her family's fishing boat used without permission, their fishing nets were cut, and human faeces were thrown at her in
14400-399: The impact of Minamata disease is complicated, as a full epidemiological study has never been conducted and patients were recognised only if they voluntarily applied to a certification council to seek financial compensation. Many individuals with Minamata disease faced discrimination and ostracism from the local community if they came out into the open about their symptoms. Some people feared
14550-407: The initial outbreak and had never been fed contaminated fish also led their mothers to believe they were not victims. At the time the medical establishment believed the placenta would protect the foetus from toxins in the bloodstream, which is indeed the case with most chemicals. What was not known at the time was that exactly the opposite is the case with methylmercury: the placenta removes it from
14700-636: The key activities; today, 24 different kinds of waste are separated. A Prize for the Environment was established to promote sustainability across Japan and South-East Asia and a prefectural environmental centre was built in Minamata. Other major events and achievements: Currently, Minamata employs a plan of reducing greenhouse gases by 32% in 2020 and by 50% in 2050 compared to 2005. Four major target areas are designated to achieve these reductions: Activities for Environmentally Friendly Living, Development of Environmentally Friendly Industries, Development of
14850-412: The lack of other industry, meant that Chisso had great influence in the city. At one point, over half of the tax revenue of Minamata City authority came from Chisso and its employees, and the company and its subsidiaries were responsible for creating a quarter of all jobs in Minamata. The city was even dubbed Chisso's "castle town," in reference to the capital cities of feudal lords who ruled Japan during
15000-536: The last European outbreak in Yugoslavia in 1972 . After over two decades of fighting smallpox, a Global Commission declared in 1979 that the disease had been eradicated – the first disease in history to be eliminated by human effort. 1974: The Expanded Programme on Immunization and the control programme of onchocerciasis was started, an important partnership between the Food and Agriculture Organization (FAO),
15150-417: The last goal for the industry is Development of a Second Eco-Industrial Housing Complex. With this program the city wants to build an industrial park mostly filled with companies that focus on the environment and the park is now filled with companies like: The different companies in the park vary in size and capacity and some companies only process products from Minamata city, while others process products from
15300-453: The late 20th century, the rise of new actors engaged in global health—such as the World Bank , the Bill & Melinda Gates Foundation, the U.S. President's Emergency Plan for AIDS Relief ( PEPFAR ) and dozens of public-private partnerships for global health—have weakened the WHO's role as a coordinator and policy leader in the field; subsequently, there are various proposals to reform or reorient
15450-488: The liability and financial burden on the company, these committees were sticking to a rigid interpretation of Minamata disease. They required that patients must exhibit all symptoms of Hunter-Russell syndrome – the standard diagnosis of organic mercury poisoning at the time, which originated from an industrial accident in the United Kingdom in 1940. The committee certified only patients exhibiting explicit symptoms of
15600-461: The manufacture of these chemicals were released into Minamata Bay through the factory wastewater . These pollutants had an environmental impact. Fisheries were damaged in terms of reduced catches, and in response Chisso reached two separate compensation agreements with the fishery cooperative in 1926 and 1943. The rapid expansion of the Chisso factory spurred on the local economy, and as the company prospered so did Minamata. This fact, combined with
15750-463: The metal. For an overview of research in 2012, see website list of research Despite the fact that anti-pollution measures and patient-support programmes started in the 1970s, it took four more decades for the Government to fully admit responsibility and apologize on-site; on 1 May 2010 Prime Minister Hatoyama was the first Prime Minister to participate in a yearly-held Memorial Service for
15900-477: The monitoring of public health risks, coordinating responses to health emergencies, and promoting health and well-being generally. The WHO is governed by the World Health Assembly (WHA), which is composed of its 194 member states. The WHA elects and advises an executive board made up of 34 health specialists; selects the WHO's chief administrator, the director-general (currently Tedros Adhanom Ghebreyesus of Ethiopia ); sets goals and priorities; and approves
16050-461: The most extensive environmental agreement systems seen below: Creating an Environmentally Symbiotic Region: Part of the goal of Minamata becoming an eco town is to maximize, protect, and integrate the town with the environment. Programs to foster and maintain ecosystems began in 1998. One specific goal is to have forests cover 75% of the city area. Other generalized goals serve to maintain and improve absorption levels of carbon dioxide, and revitalize
16200-481: The mother's bloodstream and concentrates the chemical in the foetus. After several years of study and the autopsies of two children, the doctors announced that these children had an as-yet unrecognised congenital form of Minamata disease. The certification committee convened on 29 November 1962 and agreed that the two dead children and the sixteen children still alive should be certified as patients, and therefore liable for "sympathy" payments from Chisso, in line with
16350-474: The other organization has or may have a substantial interest, the first party shall consult the other with a view to adjusting the matter by mutual agreement. The nature of this statement has led some groups and activists including Women in Europe for a Common Future to claim that the WHO is restricted in its ability to investigate the effects on human health of radiation caused by the use of nuclear power and
16500-409: The outbreak began. Another mediation committee was set up, and an agreement was hammered out and signed on 17 December. Some ¥25 million of "sympathy money" was paid to the alliance and a ¥65 million fishing recovery fund was established. In 1959, the people with Minamata disease were in a much weaker position than the fishermen. The recently formed Minamata Disease Patients Families Mutual Aid Society
16650-521: The patients asked Kumamoto Prefecture Governor Hirosaku Teramoto to include the patients' request for compensation with the mediation that was ongoing with the prefectural fishing alliance. Chisso agreed and after a few weeks' further negotiation, another "sympathy money" agreement was signed. Patients who were certified by a Ministry of Health and Welfare committee would be compensated: adult patients received ¥100,000 ($ 917) per year; children ¥30,000 ($ 275) per year, and families of dead patients would receive
16800-414: The people who sought compensation did not actually have the disease. More properly, the impact should be called a criminal 'poisoning', not a clinical 'disease'. These forms of obfuscation are commonly experienced by 'environmental victims' in many countries. WHO The World Health Organization ( WHO ) is a specialized agency of the United Nations responsible for global public health . It
16950-564: The perceived failure of the response to the West Africa Ebola outbreak , the World Health Emergencies programme was formed, changing the WHO from just being a "normative" agency to one that responds operationally to health emergencies. 2020: the World Health Organization announced that it had classified the novel coronavirus outbreak as a public health emergency of international concern. The novel coronavirus
17100-403: The plant as the source of contamination. Pollution was so heavy at the mouth of the wastewater canal, a figure of 2 kg of mercury per ton of sediment was measured: a level that would be economically viable to mine. Indeed, Chisso did later set up a subsidiary to reclaim and sell the mercury recovered from the sludge. Hair samples were taken from the individuals with the disease and also from
17250-410: The polluting companies in September 1967 and March 1968, respectively. As a group, these diseases came to be known as the four big pollution diseases of Japan . Slowly but surely, the mood in Minamata and Japan as a whole was shifting. Minamata patients found the public gradually becoming more receptive and sympathetic as the decade wore on. This culminated in 1968 with the establishment in Minamata of
17400-402: The pollution continued. In most people's minds, the issue of Minamata disease had been resolved. The years between the first set of "sympathy money" agreements in 1959 and the start of the first legal action to be taken against Chisso in 1969 are often called the "ten years of silence". In fact, much activity on the part of the patients and fishermen took place during this period, but nothing had
17550-465: The region or the country. Part of this park is made possible by subsidies,. Natural environment preservation sector: Goals: District Environmental Agreement System: There are 26 districts within the city of Minamata. Each district develops their own environmental agreement system by allowing the local residents to establish "lifestyle rules" for their district. The Kagumeishi District Residents' Association (Environment Department) has developed one of
17700-410: The researchers to believe that the outbreak was caused by some kind of food poisoning , with contaminated fish and shellfish being the prime suspects. On 4 November, the research group announced its initial findings: "Minamata disease is rather considered to be poisoning by a heavy metal , presumably it enters the human body mainly through fish and shellfish." As soon as the investigation identified
17850-550: The same year was ordered to clean up its contamination. On March 29, 2010, a settlement was reached to compensate as-yet uncertified victims. A second outbreak of Minamata disease occurred in Niigata Prefecture in 1965. The original Minamata disease and Niigata Minamata disease are considered two of the Four Big Pollution Diseases of Japan . In 1908, the Chisso Corporation first opened
18000-489: The sea with abundant marine plant life. Several districts have implemented projects to help create an environmentally symbiotic region: Utilizing New and Natural Energy: Minamata is striving to implement new and natural energy measures. Sources of natural energy: wind and solar. Wind and solar energy is mostly used for providing energy for buildings and infrastructure. Sources of new energy: bioethanol from bamboo, citrus fruit extract, thinned wood, and other plants. Bioethanol
18150-835: The sediment. This highly toxic chemical bioaccumulated and biomagnified in shellfish and fish in Minamata Bay and the Shiranui Sea , which, when eaten by the local population, resulted in mercury poisoning. The poisoning and resulting deaths of both humans and animals continued for 36 years, while Chisso and the Kumamoto prefectural government did little to prevent the epidemic. The animal effects were severe enough in cats that they came to be named as having "dancing cat fever". As of March 2001, 2,265 victims had been officially recognized as having Minamata disease and over 10,000 had received financial compensation from Chisso. By 2004, Chisso had paid $ 86 million in compensation, and in
18300-413: The street. The litigation group and their lawyers were helped substantially by an informal national network of citizens' groups that had sprung up around the country in 1969. The Associations to Indict those Responsible for Minamata Disease were instrumental in raising awareness and funds for the lawsuit. The Kumamoto branch, in particular, was especially helpful to the case. In September 1969, they set up
18450-476: The sums on offer. They petitioned the committee, together with patients and supporters of the litigation group, for a fairer deal. The arbitration committee announced their compensation plan on 25 May in a disorderly session at the Ministry of Health and Welfare in Tokyo. Thirteen protesters were arrested. Instead of accepting the agreement as they had promised, the arbitration group asked for increases. The committee
18600-477: The surface of the sea. As the extent of the outbreak was understood, the committee invited researchers from Kumamoto University (or Kumadai) to help in the research effort. The Kumamoto University Research Group was formed on 24 August 1956. Researchers from the School of Medicine began visiting Minamata regularly and admitted patients to the university hospital for detailed examinations. A more complete picture of
18750-690: The symptoms exhibited by patients was gradually uncovered. The disease developed without any prior warning, with patients complaining of a loss of sensation and numbness in their hands and feet. They became unable to grasp small objects or fasten buttons. They could not run or walk without stumbling, their voices changed in pitch, and many patients complained of difficulties seeing, hearing, and swallowing. In general, these symptoms worsened and were followed by severe convulsions, coma , and eventually death. By October 1956, forty patients had been discovered, fourteen of whom had died: an alarming case fatality rate of 35%. Researchers from Kumadai also began to focus on
18900-399: The system, the city intends to redouble efforts for the realization of "an environmental model city" making the most of the lessons from Minamata disease and fulfill the roles local governments should play in the preservation and revival of the global environment. There were multiple effects the city hoped to achieve with the implementation of ISO throughout the city: Minamata City established
19050-443: The victims of Showa Denko's pollution lived a considerable distance from the factory and had no particular link to the company. As a result, the local community was much more supportive of patients' groups and a lawsuit was filed against Showa Denko in March 1968, only three years after discovery. The events in Niigata catalysed a change in response to the original Minamata incident. The scientific research carried out in Niigata forced
19200-733: The weight of each district's recyclable garbage; large districts receive up to 600,000 yen a year and smaller districts about 70,000-80,000 yen. Besides classification, the Recycling Volunteers Committee promotes Taking-Back-Home- Garbage Campaign, Recycling Campaign, and organizes recycling fairs such as flea markets where reusable goods are sold. Because of its effort to classify garbage, Minamata City has successfully reduced its waste output significantly, from 10,000 tons in 1992 to 8,000 tons in 1994. However, it has become necessary to move beyond garbage classification to garbage reduction due to increasing garbage generation. As
19350-488: The world without prejudice to the right of the World Health Organization to concern itself with promoting, developing, assisting and co-ordinating international health work, including research, in all its aspects. The key text is highlighted in bold, the agreement in clause 2 states that the WHO is free to perform any health-related work. 1947: The WHO established an epidemiological information service via telex . 1949: The Soviet Union and its constituent republics quit
19500-530: The world. These new laws included a Water Pollution Act and nationwide regulations of toxic discharges. The polluter pays principle was introduced. A national Environmental Agency, which later developed into the Ministry of Environment, was founded in 1971. National governmental expenditures on environmental issues almost doubled between 1970 and 1975 and tripled on the local government level. Business investments in clean technologies rose dramatically, too. Minamata disease attracted global attention in 1972 during
19650-513: Was a new strain of coronavirus that had never been detected in humans before. The WHO named this new coronavirus " COVID-19 " or "2019-nCov". 2022: The WHO suggests formation of a Global Health Emergency Council, with a new global health emergency workforce, and recommends revision of the International Health Regulations. 2024: WHO has declared the spread of mpox (formerly monkeypox) in several African countries
19800-440: Was also experiencing similar problems. After a house-to-house investigation, eight further patients were discovered and hospitalised. On 1 May, the hospital director reported to the local public health office the discovery of an "epidemic of an unknown disease of the central nervous system ", marking the official discovery of Minamata disease. To investigate the epidemic, the city government and various medical practitioners formed
19950-543: Was concerning the compilation of accurate statistics on the spread and morbidity of disease. The logo of the World Health Organization features the Rod of Asclepius as a symbol for healing. In 1959, the WHO signed Agreement WHA 12–40 with the International Atomic Energy Agency (IAEA), which says: whenever either organization proposes to initiate a programme or activity on a subject in which
20100-475: Was difficult to reach. Seven of these international conferences, spanning 41 years, were convened before any resulted in a multi-state international agreement. The seventh conference, in Venice in 1892, finally resulted in a convention. It was concerned only with the sanitary control of shipping traversing the Suez Canal , and was an effort to guard against importation of cholera. Five years later, in 1897,
20250-416: Was drawn up to improve the resources available. 2005: The WHO revises International Health Regulations (IHR) in light of emerging health threats and the experience of the 2002/3 SARS epidemic , authorizing WHO, among other things, to declare a health threat a Public Health Emergency of International Concern . 2006: The WHO endorsed the world's first official HIV/AIDS Toolkit for Zimbabwe, which formed
20400-416: Was dredged and 582,000 m of land was reclaimed. On July 29, 1997, a Minamata Bay Safety Declaration was issued, nets had been removed and the environment was pronounced safe. By 2007, a total of 2,668 people were certified as Minamata disease patients, 639 of whom are alive today. Since Minamata mercury contamination event, the toxic burden of anthropogenic mercury (Hg) pollution for human and ecosystem health
20550-403: Was dying of cancer . Hosokawa explained his experiments with cats, including the infamous "cat 400", which developed Minamata disease after being fed factory wastewater. He also spoke of his opposition to the 1958 change in wastewater output route to Minamata River. Hosokawa's testimony was backed up by a colleague who also told how Chisso officials had ordered them to halt their cat experiments in
20700-399: Was finally discontinued. On 21 April 1956, a five-year-old girl was examined at Chisso's factory hospital in Minamata. The physicians were puzzled by her symptoms: difficulty walking, difficulty speaking, and convulsions . Two days later, her younger sister also began to exhibit the same symptoms and she, too, was hospitalised. The girls' mother informed doctors that her neighbour's daughter
20850-408: Was first discovered in the city of Minamata , Kumamoto Prefecture , Japan, in 1956, hence its name. It was caused by the release of methylmercury in the industrial wastewater from a chemical factory owned by the Chisso Corporation , which continued from 1932 to 1968. It has also been suggested that some of the mercury sulfate in the wastewater was also metabolized to methylmercury by bacteria in
21000-400: Was forced to revise its plan and the patients waited inside the ministry building for two days while they did so. The final agreement was signed on 27 May. Payments for deaths ranged from ¥1.7 million to ¥4 million ($ 4,700 to $ 11,100), one-time payments from ¥1 million to ¥4.2 million ($ 2,760 to $ 11,660) and annual payments between ¥170,000 and ¥380,000 ($ 470 to $ 1,100) for surviving patients. On
21150-705: Was formed. 1988: The Global Polio Eradication Initiative was established. 1995: The WHO established an independent International Commission for the Certification of Dracunculiasis Eradication (Guinea worm disease eradication; ICCDE). The ICCDE recommends to the WHO which countries fulfil requirements for certification. It also has role in advising on progress made towards elimination of transmission and processes for verification. 1998: The WHO's director-general highlighted gains in child survival, reduced infant mortality , increased life expectancy and reduced rates of "scourges" such as smallpox and polio on
21300-410: Was installed as a social solution and did nothing to remove organic mercury." The deception was successful and almost all parties involved in Minamata disease were duped into believing that the factory's wastewater had been made safe from December 1959 onward. This widespread assumption meant that doctors were not expecting new patients to appear, resulting in numerous problems in the years to follow as
21450-481: Was much more divided than the fishing cooperatives. Patients' families were the victims of discrimination and ostracism from the local community. Local people felt that the company (and their city that depended upon it) was facing economic ruin. To some patients, this ostracism by the community represented a greater fear than the disease itself. After beginning a sit-in at the Chisso factory gates in November 1959,
21600-537: Was responsible for the disease proved to be extremely difficult and time-consuming. During 1957 and 1958, many different theories were proposed by different researchers. At first, manganese was thought to be the causal substance due to the high concentrations found in fish and the organs of the deceased. Thallium, selenium, and a multiple contaminant theory were also proposed, but in March 1958, visiting British neurologist Douglas McAlpine suggested that Minamata symptoms resembled those of organic mercury poisoning , so
21750-423: Was stacked heavily in the company's favour. On 29 August, the fishing cooperative agreed to the mediation committee's proposal, stating: "In order to end the anxiety of the citizens, we swallow our tears and accept". Chisso paid the cooperative ¥ 20 million (US$ 183,477 — about US$ 1.7 million in 2021 value) and set up a ¥15 million ($ 137,608 — about 1.25 million today) fund to promote the recovery of fishing. Since
21900-429: Was that of a woman from Goshonoura island who had 920 ppm in her sample. The prefectural governments did not publish the results and did nothing in response to these surveys. The participants who had donated hair samples were not informed of their result, even when they requested it. A follow-up study ten years later discovered that many had died from "unknown causes".
