PCBs: What are they and why are they considered a problem?

The major problem is that 94% of America’s waterways sampled by EPA are contaminated with polychlorinated biphenyls (PCBs) and other persistent organic pollutants (POPs) that do not degrade naturally in the environment.

PCBs are now the most widespread contaminant on earth.

Due to industrialization, almost every country used and still uses PCBs to manufacture everyday goods. It is estimated that more than half of the PCBs ever produced have been released into the environment causing worldwide animal, community, and human health damage estimated into the trillions of dollars.
