Toxic Pollution of marine environment (water, bottom sediments and hydrobionts) has been one of the main Black Sea problems. The aim of our studies in framework of PERSEUS
project has been to investigate the current state of marine environment toxic pollution with
trace metals (TM), organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and
polyaromatic hydrocarbons (PAHs) in the Zmiinyi Island area, which according to our
previous studies is the area with practically natural conditions. During 2011-2013 the
Research Station of Odessa National I.I.Mechnikov University carried out the sampling
programme. Analyses of marine environment samples have been carried out in accordance
with the national methods and the methods recommended by the ISO in the laboratory of the
Ukrainian Scientific Centre of the Ecology of Sea. The data on coastal sea waters, bottom sediments and fish and molluscs pollution for 2011-2013 with OCPs, PCBs, TM and PAHs are presented and being analyzed. Analyses of the results of marine environment pollution
studies have shown that toxicity of water and bottom sediments in 2011-2013 decreased
compared to previous years. The origin of pollution in coastal waters, sediments and fish and
mussel species near the Zmiinyi Island is being discussed. Coefficients of pollutants
accumulation in fish and mollusk tissues have been calculated and are discussed using the
data on the pollutants' concentration in water. It is proposed to study the levels of TMs, OCPs
and PCBs accumulation in hydrobionts in more details depending on the age of hydrobionts
(fish and mollusks) and, first of all, on the peculiarities of their food chains, from which
accumulation of toxicants in their tissues takes place. The main conclusions of our studies
during 2011-2013 are the following: the levels of pollution for all toxicants are lower than in
previous years; the results of comparison with the other Ukrainian areas of the Back Sea has
shown that the Zmiinyi Island area could be used as a reference area.
