The materials on the study of the content of heavy metals and organochlorine pesticides in fish are presented. It has been established that the level of heavy metals and pesticides in fish is influenced by the territorial location of the pond production. Therefore, the content of lead, cadmium and mercury in the liver and gonads of carp was higher than the permissible values for fish growing in ponds located in the city limits near highways. The pesticides DDT and HCH were detected in the organs of fish in the territories of pond fish farming of farms. Residual concentrations of pesticides contained in fish did not exceed the maximum permissible levels. In order to safely consume fish grown near highways by the population, we recommend the removal of internal organs (liver and gonads) from fish products.
