Abstract
Organochlorine pesticides and various metals were determined in mussels, sands and crabs from a lake to assess the local pullution by these chemicals and their hiomagnification in these organisms from the surrounding water. a-, 0-, 7- and 8-isomers of HCH, PP'-DDT, OP'-DDT, PP'-DDE and PP'-DDD were the pollutants found to be biomagnified in the three organisms several fold from the water. Mussels mainly accumulated lead and nickel while snails concentrated zinc and copper substantially. Results demonstrate that these ortanisms may be used to monitor pollution of the environment.
