Chapter 15: ENVIRONMENTAL TOXICITY POLYCLOBIPHENYLThe PCB is polyclobiphenyl chemical durability and very high biological durability, low evaporation pressure and there is a dielectric. Thanks to the nature that people use the PCB do cold fluids, insulation of the transformer and the capacitor, in the application to do the cotton fiber cement and osmosis, do the plasticizer and as additives for some êpoxy paints, pesticides.The most common way to PCBs enters the human body through plants, seafood, atmosphere. They can remain stored in the fatty tissue of living organisms. When the children contaminated substances, poisonous substances that hinder the acquisition of children's lessons, hinder the development of full capacity. The human immune system damaged by contaminated PCBs. PCBs can quickly penetrate to the inside of the skin, through the wound. The contaminated PCBs can relate to with these birth defects. Listening out seem strange but true many studies have shown, the accumulation of toxic PCBs in the fish on the river pollution have made genetically caused the birth defects. The new study showed that PCBs are factors that promote cancer birth process. Avoid eating fish and wildlife from the area of the River, Lake or Bay is the source of contaminated effluents receiving PCBs. All fish and ducks live on the rivers that are contaminated with toxic PCBs, avoid eating contaminated fish, because they can accumulate PCBs in the body PCBs, and goes on in the body of our future descendants.
