I believe it was the last 70's when they stopped using PCBs in electrical
equipment.
PCBs are pretty harmless unless you snack on your electrical equipment. They
were banned because of suspicion they might be harmful if accumulated in
people or animals. In any case, the PCBs they find in lakes and fish were
from marine engine coolant which was PCB based, not electrical equipment.
