title: Оценка состояния загрязнения донных осадков тяжёлыми металлами в прибрежных районах Крыма (Чёрное море)
abstract: The paper presents results of definition of heavy metals concentrations (Pb, Cd, Cu, Zn, Ni, Hg, Cr) in a surface layer of bottom sediments in coastal waters of Crimea. Comparison of heavy metals in regions with their concentrations in open areas of Black Sea, with their natural clarkes in lithosphere and permissible levels of polluting substances on the Dutch sheets is spent. Values are calculated of factors and indexes of degree of heavy metals pollution in bottom sediments.
