Editor’s Note: This is the fifth installment in a series of posts looking into some of the the chemical pollutants that have contaminated Puget Sound’s fish and wildlife and pose one of the greatest threats to their survival. This is part two of a two-part series, The Chemicals That Just Won’t Go Away, that examines polychlorinated biphenyls (PCBs), which are still polluting people and the environment despite being banned over 30 years ago.
This post was written by Dr. Fran Solomon, an environmental biologist who teaches courses and gives seminars for university students, environmental and health care professionals, and the general public about toxic chemicals and how they affect human health and the aquatic environment.
