NTL 1973-G03 - The Use of Polychlorinated Biphenyls (PCB's) - February 16, 1973

Certain potential adverse environmental effects have been recognized in the use of polychlorinated biphenyls (PCB's) in liquid heat transfer units. Until recently, the impact of the introduction of PCB's to the environment has gone unnoticed. However, present research on PCB's has indicated them to be chronically toxic to the ecosystem.
