Abstract: With the rapid increase in the amount and variety of organic pollutants entering into ecosystems,more and more attention has been paid to the ecological effects of chlorohydrocarbons,and the research on the ecological behavior and toxicological effects of chlorohydrocarbons has become a hot-spot and focusing content of environmental sciences and pollution ecology.In order to have a better understanding of these pollutants,this paper summarized the current situation of the polluting sources of chlorohydrocarbons,including chlorinated aliphatic hydrocarbon,chlorobenzenes and chlorofluorocarbons,and on the basis of their hydrophobic nature,volatility and stability,discussed the migratory behavior of the toxic organic pollutants in environment and their related biological enrichment,accumulation and magnification behaviors.A research progress on the acute toxicity of chlorohydrocarbons on fishes,and their influenced contents of retinoids and α-tocopherols,possible teratogenicity,mutagenesis and phytotoxicity was reviewed by analyzing QSARs,which could provide a scientific basis for promoting the going deep into a new level in the field of chlorohydrocarbon pollutants.
