are a group of synthetic organic chemicals that can cause a number of harmful effects. PCBs were used widely as coolants and lubricants for transformers, capacitors, and other electrical equipment. Some PCBs are volatile and may exist as a vapor in the air. PCBs enter the environment as mixtures containing a variety of individual chlorinated biphenyl components.
