Assessment of ecological safety of fish from anthropogenically polluted freshwater reservoir

The content of heavy metals in fish different ecological groups the conditions Argazinsky reservoir (Russia) has been studied, its safety when used as a product nutrition was given. material study “local” (bream, pike, perch, roach, whitefish) caught by fishermen. determined atomic absorption method. Compared to muscular tissue, bone tissue found accumulate more manganese, zinc, cadmium, lead, cobalt, nickel, iron (except for roach), copper, except perch. value metal pollution index (P i ) is greater than one bream muscles lead and cobalt; pike — nickel. multifactor contamination (MPI) are located following order: > whitefish Pi >1.0 skeletal iron; manganese; perch cadmium; roach cadmium. By magnitude MPI, ranked Pike MPI=3, 85, 10. row formed fatness: pike. fatness amount body affected excessively accumulated (nickel, cobalt bream, pike), - essential (iron, copper zinc whitefish).
