Pollution-Fueled "Biodeterioration" Threatens Historic Stone The deterioriation of cultural and artistic treasures may be accelerated by the actions of microorganisms fueled by air pollution. Patrick Young reports on this emerging research area. / 206A
Air Quality Modeling's Brave New World State and regional regulators will soon be able to use sophisticated computer modeling to design air quality control strategies, according to EPA model developers. Elaine Appleton reports on Models-3, the agency's next-generation modeling system that will be able to tackle complex regional and multipollutant issues. / 200A
Estrogens May Link Pesticides, Breast Cancer A better understanding of estrogen coupled to findings on the estrogen-like nature of many pesticides has led researchers to suggest a hypothesis for how chlorinated pesticides might cause breast cancer. Margie Patlak reports on the controversial hypothesis. / 210A

Proposed dredged sediment tests criticized Environmentalists say a proposal to modify test stan dards for dredged sediments will open the door to ocean dumping of millions of tons of toxic spoils; EPA officials strongly disagree. / 197A
EPA backtracks on mercury study Reversing themselves again, EPA officials say they will not release a controversial study of risk from mercury exposure. Instead, EPA turns to its Science Advisory Board and predicts the report's release will be put off by up to two years. / 193A
U.S. ends 16-year ban on PCB imports EPA says its decision to end a ban on PCB imports for treatment and disposal will give a boost to U.S. hazard ous waste firms. Some in industry doubt EPA's figures. Environmental groups sue. / 198A
