There was a similar pattern of uncertainty in judgments about Alar, radon and even some forms of PCBs and asbestos. Citing government studies, environmentalists sounded the alarm about toxicity and cancer. The public fretted. Officials issued warnings and regulations. But then skeptical scientists re-evaluated the threat and began to argue that the risks had been exaggerated. After this series of debates, people are wondering if they have been unduly frightened by overzealous, if well-meaning, regulators...
...extensively even in the genetic restructuring of some species. For instance, the triploid oyster, still in the experimental phase, is rendered sterile with antibiotics and thus does not go through an uneatable mating phase; it is harvestable all year. On the other hand, wild fish are vulnerable to parasites, PCBs and a host of other pollutants...
...current issue of Microwave News, Slesin has printed what may be his greatest scoop: the key paragraph of a two-year Environmental Protection Agency study recommending that so-called extremely low-frequency fields be classified as "probable human carcinogens" alongside such notorious chemical toxins as PCBs, formaldehyde and dioxin. The recommendation, which could have set off a costly chain of regulatory actions, was deleted from the final draft after review by the White House Office of Policy Development. "The EPA thing is a stunner," says Paul Brodeur, a writer for the New Yorker. "It's a clear case of suppression...
...cases joining the loose environmental coalitions that have become major lobbying forces in state capitals. When her second son was born with a breathing disorder, Marylee Orr roused her Baton Rouge neighborhood and founded Mothers Against Air Pollution to stop a nearby incinerator from releasing toxic polychlorinated biphenyls, or PCBs. Now the 38-year-old housewife heads the Louisiana Environmental Action Network, an umbrella for about 50 local environmental hell raisers, which lobbied successfully last year for the passage of the state's first air- quality law. In New Jersey the social-studies class of teacher Karl Stehle at West...
...mounted annual inspection tours of dozens of bases. It was Greenpeace that publicized McMurdo's continued dumping of untreated sewage into the sea and burning of trash in an open-air pit. The waters right off the station are reportedly more polluted with substances such as heavy metals and PCBs than any similar stretch of water in the U.S. Greenpeace has also documented reckless dumping and burning at Soviet, Uruguayan, Argentine, Chilean and Chinese bases. And an airstrip under construction at France's Dumont d'Urville base has already leveled part of an Adelie-penguin rookery...
