Визначення потоків радіоактивних і мінеральних речовин природного та техногенного походження між компонентами екосистеми Чорного моря. Діагностика критичних зон. Head Egorov V.N., Registration Date 25-05-2010 Organization Kovalevsky Institute of biology of the southern seas, NAS of Ukraine popup.description2 Critical zones in the Black Sea Ukrainian economic zone concerning organic-chlor conjunction and mercury were identified. Critical levels of chromosome mutagenesis of the different taxons hydrobionts populations, under which decrease of their adaptive potential is possible, were revealed. Dynamics of the Crimean salty lakes biosedimental self-purification processes for the past 50 - 100 years taking into consideration anthropogenic pressure and regional climate was reconstructed. Velocity of the precipitations accumulations in the Streletskaya bay was determined, inflows of the post accident radionuclides into the bay bottom sediments were evaluated using the post Chernobyl-accident radionuclide 90Sr as the radiotracer. It was obtained, that concentration of 210Pb in the carbonate material of the deep-water bacterial constructions is surplus in comparison with maternal radionuclide 226Ra, which testify to income of radon - 222 together with metane and can be used for the methane oxidation velocity calculation Product Description popup.authors Гулін С.Б.
