They are a byproduct of certain industries. Chlorine is a very caustic (eats things up) agent, that is why it is used in pools and sewage treatment, in large quantities it can be deadly to humans. These can build up in marine animals, fish, called bioaccumulation, so when a human eats it they get poisoned by it. Phenyls are also very acidic. PCB stands for Polychlorinated Biphenyls.
