PCB Contamination

Since the production of PCBs in 1954, 57,000 tons of PCBs have been produced, and Dr. Isono of Tokyo Metropolitan University has warned that it will affect the next generation. The cause was PCB (polychlorinated biphenyls) used in the deodorization process of rice bran oil. Later, it was discovered that the real cause was dioxin, which was mixed in with PCBs to a very small extent. Until now, PCBs were said to be the cause of Kanemi's oil disease, but in fact, dibenzofuran, which is formed when PCBs are heated, is the real cause. 　 An interview with a patient on PCB testing An interview with Dr. Isono of Tokyo Metropolitan University on an experiment with chicks at the Tokyo Metropolitan Government's Hygiene Testing Department Footage of environmental destruction, *Filming date unknown, release date: June 16, 1972. .
