Polychlorinated
biphenyl
Polychlorinated biphenyl (PCB) are man made chemicals consisting of
carbons, hydrogen, and chlorine atoms. Due to their beneficial chemical
properties, PCBs were widely used by industrial companies and applications. In
1979, PCBs were banned in the United States because of heightened health risks
associated with PCB contamination. Currently PCBs are located in river
sediments and floodplain soil. As a
result these chemicals can be found in the
fish and food that we eat. PCBs enter the air, water, and soil during
manufacture and leaks from products created by the industrial companies. After
entering into the environment, PCBs are hard to degrade due to their complex
structure leading to bioaccumulation. Anyone who eats fish is at risk for PCB
contamination and should learn how to reduce risks related to PCBs. Learning
how to properly cook and clean fish is one way to reduce PCB consumption.
