Mysterious poison. History of PCBs
Description
They are now banned worldwide-but the toxins known as PCBs are not going away. This program explains how the compounds have almost irreparably polluted the globe and still threaten future generations. The film begins in 1927, when PCBs became integral to electric power and, eventually, a vast array of agricultural and technological products. Describing the growth of scientific awareness of PCB-related threats across the food chain, the program features compelling interviews with researchers who helped uncover the hereditary hazards of PCBs-including World Wildlife Fund senior scientist Dr. Theo Colburn and University of Stockholm professor Soren Jensen.
