Comparison of the cytogenetic and ecosystem efficiencies of the effect of radioactive and chemical mutagens in hydro biosphere

Equivalent doses of ionizing radiation and chemical mutagens { Pb(2+). Chloroprene,DDT }, inducing chromosome aberrations in embryos cells of amphipod Gammarus olive and fish Scorpaena porcus in the Black Sea are compared and expressed in general units, namely: Gy equivalents. Cytogenetic data obtained by us during short-term experiments are discussed together with the literature data on extinctions of hydrobiont species in the micro cost under nuclear and nonnuclear impacts
