Аналіз токсикологічних, модифікуючих та адаптивних ефектів біогенів у риб. Моделювання впливу антропогенних факторів (хімічного, біологічного забруднення, біогенів, іонізуючої радіації) на біоту гіпергалінних водойм.

The revealed level of the studied water area pollution effected not much the level of energy exchange in epiplankton community mass species, acarcia and mnemiopsis, under food abundance and during their mass reproduction. Life activity inhibition in weakened starved or spawned parts of population increased under complex pollution, playing role of additional limiting factor. We received data on pollution of the bottom sediments in the Sevastopol bay water area with heavy metals (Cd, Cu, Pb, Zn, Co, Ni, Cr), arsenium and oil hydrocarbons in 2008. The long-term dynamics in changes of contents of heavy metals, arsenium and oil hydrocarbons in the Sevastopol bay bottom sediments has been studied for the first time. It has been stated, that toxic elements concentrations (Cu, Zn, Pb, Cd, As, Hg) in the tissues of bottom and near-bottom fish and mollusks at the Sevastopol coast did not exceed marginal acceptable level. On the base of original methology of evaluation of deeutrophicative effectiveness of the coastal ecosystems numerical estimation of value and structure of the biogenic elements flow through the Kruglaya bay bottom biocenosis has been conducted for the first time.
