MERCURY CONCENTRATIONS IN MUSCLES OF DIFFERENT FISH SPECIES FROM WATER BODIES OF YAROSLAVL REGION AND ADJACENT TERRITORIES

Mercury (Hg) and its compounds, which pose a health risk to the population not engaged in hazardous industries, enter human body mainly with food items. First of all, these are seafood, fish canned fish. In this study, concentrations Hg muscles different species from water bodies Yaroslavl province were determined. The average values mercury content range 0.03 0.41 mg/kg wet weight. recorded levels accumulation correspond or close previously obtained freshwater reservoirs European part Russia states. species-specificity process, dependence on trophic specialization size-weight characteristics fish, as well type reservoir noted. regulatory standards established Russian Federation for non-predatory (<0.3 w.w.) predatory (<0.6 exceeded 0.3% 16% studied respectively.
