New Contaminant Invades Arctic Air

rnal is published by the American Chemical Society, the world's largest scientific society.

"Iron sulfate appears to both stimulate the growth of PCB dechlorinating bacteria so that there are more of them and hence more activity, and also to reduce toxicity of byproducts of dechlorination that inhibit further dechlorination," said Stephen Boyd, Ph.D., lead scientist for the study and a professor in MSU's Institute for Environmental Toxicology. "No one else has ever tried this approach," according to Boyd. Prior to this, he said, "there were no reliable and practical methods to stimulate the most important dechlorination processes."

The study involved sediments from the upper Hudson River near Hudson Falls, N.Y.
