This article reviews the composition of persistent organic pollutants, environmental pollution, migration and transformation in the environment act, the process of enrichment through the food chain, ecological systems and even the harmful effects of humans, to underscore the persistent organic pollutants Environmental pollution has become a global environmental problems, environmental health and safety and food hygiene and safety a major issue. Keywords: Persistent organic pollutants; sources; biota; food chain CLC: R139.3 Document code: A Article ID: 1001.1226 (2003), organized by the United Nations Environment Programme 100 03.0169-04 countries, hundreds of people on the disabled to participate in intergovernmental POPs 12 international conventions, negotiations lasted several years, culminating in the May 2001 contract in Stockholm, Sweden. 12 listed in the Convention on persistent organic pollutants: aldrin (aldrin), dieldrin (dieldrin), endrin (endrin), DDT (DDT), chlordane (chlordane), toxaphene (toxephene), mirex (mirex), six chlorine (generation) benzene (hexaehlorbenzene), heptachlor (heptachlor), polychlorinated biphenyls (PCBs), polychlorinated dibenzofurans and two British and polychlorinated dibenzo Hey and furans (PCDD / Fs). In addition, more international studies including polybrominated diphenyl ethers, polybrominated naphthalenes, and polybrominated diphenyl chew two British and polybrominated dibenzofurans, polychlorinated naphthalene, chlorinated phenols, polycyclic aromatic hydrocarbons, phthalate Received :2002.10-31; Revised :2003.02-17 esters and alkylphenol ethoxylates, etc .... The so-called persistent organic pollutants is difficult for these substances in the environment, degradation of water vapor through evaporation, air flow in air, easily in organisms, including human fat tissue accumulation, and the entire ecosystem of human potential caused by hazards. These substances in the environment is the major source of synthetic industrial chemicals such as organochlorine pesticides, polychlorinated biphenyls, polychlorinated naphthalenes and polybrominated diphenyl ethers, phthalates, etc., and PCDD / Fs are mainly waste incineration and other combustion, metal smelting, chlor-alkali industry, pulp and paper, and other chlorine by-product of chemical processes. Present results show that the United States and Europe since the 20th century, 70 years, as people gradually realized that some of the traditional persistent organic pollutants such as organochlorine pesticides, PCBs and PCDD / Fs in the environment, persistence,
