Harbor zoobenthos of north-east shelf of the Black Sea and its relation with pollution of sed iments
Zoobenthos composition and distribution of anthropogenic polluted loosebottom in ports of Novorossiysk and Tuapse cities were studied. Behavior of zoobenthos biomass was analyzed using estimation of accumulation gradients of oil hydrocarbons and unstable (acid-soluble) sulfides in bottom top layer. Accumulation of fauna toxic unstable sulfides and migration to bottom surface of reduced components with concentration increasing 500 mg S / dm3 of fresh sludge is dangerous ecological effect of anthropogenic pollution causing bottom biocenos to be degradated.
