645-790: The Environmental Law Institute , Davis began publishing articles examining links between environmental chemicals and cancer. Davis was appointed resident scholar at the National Research Council of the National Academy of Sciences in 1989. In 1990, she led a study published in The Lancet along with National Institute for Environmental Health Sciences director David Hoel, British census director John Fox , and World Health Organization statistician Alan Lopez , examining cancer rates in
688-408: The 1948 event more severe was a temperature inversion , a situation in which warmer air aloft traps pollution in a layer of colder air near the surface. The pollutants in the air mixed with fog to form a thick, yellowish, acrid smog that hung over Donora for five days. The sulfuric acid , nitrogen dioxide , fluorine , and other poisonous gases that usually dispersed into the atmosphere were caught in

#1732779630520946-479: The book "a welcome addition to the struggle to correct the imbalance" between curative and preventative research, while science writer Fred Pearce wrote it "is a rattling good read and raises vital issues that remain relevant today." In a positive review, science journalist Dan Fagin called Davis "her generation's strongest advocate of the idea that synthetic chemicals are a seriously under-recognized cause of cancer." Medical historian Peter Keating, however, found
989-426: The book "largely unoriginal" and poorly organized. Epidemiologist Peter Boyle wrote that "devotees of conspiracy theories and aficionados of gossip and innuendo will be drawn towards this book like wasps to a juicy piece of meat" and discussed how the book suggested that the link between tobacco and cancer was used to distract from other possible sources. In 2007 Davis founded the Environmental Health Trust (EHT),
1032-464: The burgess (mayor) of Donora, requested the plants temporarily cease operations. The superintendent of the plants, L.J. Westhaver, said the plants had already begun shutting down operation at around 6:00 that morning. With the rain alleviating the smog, the plants resumed normal operation the following morning. Researchers analyzing the event have focused likely blame on pollutants from the zinc plant, whose emissions had killed almost all vegetation within
1075-519: The company was prepared to show at trial that the smog had been caused by a "freak weather condition" that trapped over Donora "all of the smog coming from the homes, railroads, the steamboats, and the exhaust from automobiles, as well as the effluents from its plants." U.S. Steel closed both plants by 1966. By 1949, a year after the disaster, the total value of the predominantly residential property in Donora had declined by nearly 10%. The Donora Smog
1118-560: The deaths. Further research was conducted by Mary Amdur about the effects of the smog; she was pressured to withdraw publication of these results but refused to be bowed. Preliminary results of a study performed by Clarence A. Mills of the University of Cincinnati and released in December 1948 showed that thousands more Donora residents could have been killed if the smog had lasted any longer than it had. Lawsuits were filed against U.S. Steel, which never acknowledged responsibility for

The smog was so intense that driving was nearly abandoned; those who chose to continue driving took risks. “I drove on the left side of the street with my head out the window. Steering by scraping the curb.” recalled Davis. It was not until Sunday morning, the 31st, that a meeting occurred between the operators of the plants and the town officials. August Z. Chambon,

The incident was little spoken of in Donora until a historical marker was placed in the town in 1998, to commemorate the 50th anniversary of the incident. The 60th anniversary, in 2008, was commemorated with memorials for the families of the victims and other educational programs. The Donora Smog Museum was opened on October 20, 2008, located in an old storefront at 595 McKean Avenue near Sixth Street, with

1376-433: The incident was described by The New York Times as "one of the worst air pollution disasters in the nation's history." Even 10 years after the incident, mortality rates in Donora were significantly higher than those in other communities nearby. Hydrogen fluoride and sulfur dioxide emissions from U.S. Steel 's Donora Zinc Works and its American Steel & Wire plant were frequent occurrences in Donora. What made
1419-444: The incident, calling it "an act of God". While the steel company did not accept blame, it reached a settlement in 1951 in which it paid about $ 235,000, which was stretched over the 80 victims who had participated in the lawsuit, leaving them little after legal expenses were factored in. Representatives of American Steel and Wire settled the more than $ 4.6 million claimed in 130 damage suits at about 5% of what had been sought, noting that
1462-583: The inversion and accumulated until rain ended the weather pattern. The fog started building up in Donora on Wednesday, October 27, 1948. By the following day it was causing coughing and other signs of respiratory distress for many residents of the community in the Monongahela River valley. Many of the illnesses and deaths were initially attributed to asthma . The smog continued until it rained on Sunday, October 31, by which time 20 residents of Donora had died and approximately one third to one half of

Other writers have compared and Davis and Carson, both in their styles and themes of writing and their small town Pennsylvania upbringings. Epidemiologist Bert Brunekreef wrote the book is "at its best when describing how commercial interests have harassed well known environmental health scientists in attempts to downplay

Davis' second book, The Secret History of the War on Cancer , was published in 2007. In it, she argues that medical institutions involved in the " war on cancer " have focused more on cures than on prevention , and that some safety research into environmental toxicity suffers from
1591-484: The slogan "Clean Air Started Here". Fewer than 6,000 people still live in Donora. The Donora event led to the first large-scale epidemiological investigation of an environmental health disaster in the United States. An account of the smog was published in 1950 by the noted medical writer Berton Roueché in The New Yorker under the title "The Fog". Together with another article, "A Pig From Jersey" (about
1634-552: The town's population of 14,000 residents had been sickened. Another 50 residents died of respiratory causes within a month after the incident; notable among the fatalities was Lukasz Musial, the father of future baseball Hall of Famer and the 1948 National League MVP Stan Musial . Two of the heroes to emerge during the four-day smog were Chief John Volk of the Donora Fire Department and his assistant Russell Davis. Volk and Davis responded to calls from Friday night,

Landrigan and biostatisticians such as John C. Bailar and Thomas C. Chalmers . Davis was appointed by President Clinton to the US Chemical Safety and Hazard Investigation Board . In 1997 she was working as a consultant to the World Health Organization and served as

The episode drew heavy criticism from researchers, and Davis' claims were refuted by public health scholar Simon Chapman , who claims there is no evidence of increase brain cancer rates in Australians, as well as Rodney Croft,
1849-533: Was one of the incidents where Americans recognized that exposure to large amounts of pollution in a short period of time can result in injuries and fatalities. The event is often credited for helping to trigger the clean-air movement in the United States, whose crowning achievement was the Clean Air Act of 1963 , which required the United States Environmental Protection Agency to develop and enforce regulations to protect
