PCB's and the enviroment
Life is a precious element to a broad range of creatures. When a chemical toxin invades life's environment, we should all be concerned. Polychlorinated biphenyls (PCBs) are a group of chemical compounds that are invading and polluting the environment. They cause severe health problems in humans and affect many creatures in nature. Scientist found high PCB levels in two orca whales that washed up dead last February near the Strait of Juan de Fuca (Ko, 2002). The United States Environmental Protection Agency claims they are quick to act on all PCB discoveries, but it may be too late. There are some remedies to remove PCBs from the environment, but it doesn't take care of the entire problem. Polychlorinated biphenyls are a group of chemicals compounds that have no molecular breakdown. They were used by the industrial manufacturing industry between 1930-1970. They were primarily used as electrical insulators in transformers and other electrical equipment. They were also used in a variety of products such as: power saws, typewriters, cereal boxes, and bread wrappers (Heimlich, 2002). They were released into the environment during their use by smokestacks, leakage of old equipment, leaching from landfills, and other pollut
PCBs are causing severe abnormalities in the Polar Bear population in the Artic. Several cubs have been found with both male and female sex organs. This is believed to be caused by industrial pollution from Europe and Asia. As you can see PCBs affect every aspect of the environment.
