SPECIFIC FEATURES OF DISTRIBUTION OF MINERALS IN ORGANS AND TISSUES OF HERRING SPECIES (CLUPEIDAE) IN CASPIAN SEA

Research objective was to identify the specific features of distribution microelements (zink, manganese, lead, cadmium) in organs and tissues black-backed shad Alosa kessleri (Grimm, 1887) Dolginsky herring braschnikowii (Borodin, 1904) caught Caspian Sea. Accumulated fish concentrations exceeding maximum permissible limits, heavy metals pose a danger human health. Sampling carried out by standard techniques, definition minerals made method atomic absorbing spectroscopy using an spectrometer with electrothermal atomization MGA-915 MD. The analysis obtained data showed that studied species had similar pattern: highest were registered gills liver, smallest - muscle tissue. In comparison higher chemical elements. Zinc has been found accumulate mainly liver; lead cadmium gills. Accumulation zinc, bodies fishes exceeded acceptable level.
