Last week the court rebuffed both the Administration and the textile manufacturers. In a decision that could have considerable impact on many industries beyond textiles, the court ruled, 5 to 3, that the agency is not required to weigh costs against benefits when setting health standards dealing with toxic materials in the workplace...
Scientists have linked dioxin, the most toxic element in Agent Orange, to cancer in animals. Researchers in Italy and Viet Nam claim dioxin is tied to birth defects in humans. Veterans also blame the chemical for headaches, sexual dysfunction and organ damage. They say perhaps 80,000 soldiers were exposed to dioxin. The Federal Government says there is no way to tell, although some 45,000 soldiers have been tested and a federally financed study is under way at the University of California at Los Angeles School of Public Health...
...Spielberg, white blood cells from humans are mixed with liver tissue from humans or other species plus the drug under study. Then the preparation is examined to see if enzymes in the liver have metabolized the drug into a substance that kills white cells. The researchers believe that such toxic metabolites may be responsible for birth defects; some of their studies suggest that thalidomide works that way. The new test, for instance, shows that thalidomide does form a toxic metabolite, areneoxide, in the presence of liver tissue from rabbits, monkeys and humans, though not from rats...
Blake and Spielberg caution that this test will not alert investigators to all drugs with the potential for causing birth defects, only to those that form toxic metabolites. But they think their work could help researchers design more reliable experiments. For example, if a test shows that a .particular drug forms a toxic metabolite in humans and rabbits, but not, say, in dogs, then by a process of elimination rabbits would be designated the appropriate species for future birth defect studies related to that drug...
...safeguarding America's natural resources. Year after year Congress came through nobly, enacting such landmark legislation as the Clean Air and Clean Water acts, and a series of bills designed to protect endangered species. In 1980 the nation's legislators even created a "superfund" to clean up toxic-waste dumps. The new Administration plans to reverse much of that. Says Audubon Society President Russell Peterson, Reagan is "trying to turn back the clock...
