"Oxygen-starved bacteria working in sediment beneath the Hudson River are transforming toxic PCB compounds into less dangerous forms, raising hopes of a significant easing of a major PCB cleanup problem nationwide," researchers said yesterday.
"The resulting types of PCBs do not accumulate in living tissue, a government scientist said."
Researchers at the University of Michigan stated that it appeared that these bacteria had evolved specifically to attack PCBs.
