As a kind of pesticide, fungicide and preservative, PCP had been used extensively in industry, agriculture and domesticity throughout the world. PCP contamination is generally associated with sediments or soil, it can also concentrate in organism. Regarding the character of high toxicity, long persistence and difficult to degrade, PCP has become a kind of conspicuous environmental pollutant because of widely use and inappropriate disposal. In the contaminated area, PCP can be detected in the water, soil and the body of organisms. PCP can affect human health through directly exposure or through food chain. The absorbed PCP can be stored in liver, kidney and fat,it can also increase the incidence rate of tumork, disturb the endocrine system, affect immune function,inhibit reproduction and development. PCP not only has a direct impairment on human body but also shows a potential impact in genetics.
