Organochlorine Pesticide (HCH and DDT) Residues in Dietary Products from Shaanxi Province, People's Republic of China

摘要

Organochlorine (OC) pesticides are employed on a massive scale both in agriculture and in public health in China. OC pesticides such as HCH (hexachlorocyclohexanes), and DDT (dichlorodiphenyltrichlorethane), bioaccumulate in the food chain and thus the exposure to OC compounds can occur through the diet, environmental sources, and occupational activities. Due to their high toxicity, lipophilicity, and persistence, the production and use of HCH and DDT have been banned, phased out, or strongly restricted for several decades in most developed countries (Voldner and Li 1995) and it has been the same in China, since 1983 (Chinese Ministry of Agriculture 1989).
