...that have been tested in one microbial system, 90 per cent of those that scored positive for mutagenicity were also found to induce tumors when studied in animals. In light of this high correlation between mutagenicity and carcinogenicity, test systems for mutagenicity are being used increasingly to identify potentially toxic substances early in product development. Recent reports do indicate that saccharin-containing products produce mutations in test systems...
...constant skirmishing with companies, the Environmental Protection Agency last week won its biggest victory yet in a water-pollution case. After five years of litigation, U.S. Steel Corp. agreed to stop dumping cyanide, ammonia and phenols-all toxic pollutants-into Lake Michigan and the Grand Calumet River from its huge works at Gary, Ind. It has been pumping out 16,700 Ibs. a day of solids, part of them toxic...
...have not seen lawyers, that unreasonable sentences have been imposed, that Gov. Thomson and the assistant attorney general have twisted the court system to make life difficult for us. Our central concern, however, continues to be nuclear power. The insanity of a national energy economy based on an incredibly toxic carcinogen, plutonium; the public's blindness to the incredible costs of the nuclear fuel cycle, from uranium mining to fuel fabrication to power reactors to reprocessing plants to waste storage; the deliberate suppression of alternate energy sources like wind and solar; a technology that even government sources admit is capable...
...They discovered that cattle in his herd, and those on at least seven other farms in the state, have been ingesting a wood preservative called pentachlorophenol (PCP)-probably when the animals licked the sides of their feed bins. Because the preservative contains dioxin, a substance related to the highly toxic chemical that has made the Italian town of Seveso uninhabitable, state officials banned sales of PCP and quarantined suspect cattle. No PCP-contaminated milk has reached the state's consumers. But some stores in Michigan have begun advertising that they sell only out-of-state beef...
...trucker had been transporting fuel in his tanks to Iowa, where it was to have been sprayed on the state's gravel roads to keep down the dust. Trouble was that some of the fuel, a solvent, was heavily contaminated with polychlorinated biphenyls (PCBs), a class of highly toxic chemicals that have been implicated in birth defects and nervous disorders. Environmental officials were notified; they located the contaminated solvent in Cedar Falls and Fort Dodge, Iowa, before it had been used. Had the solvent been spread on Iowa's roads, it could have found its way into animals...
