Bogatova Y. Mechanisms of formation of the Danube nutrients runoff (Ukrainian part) and its role in eutrophication of the north-western part of the Black Sea

Object - delta region of the Danube. Purpose - to obtain quantitative and qualitative characteristics of the Danube nutrients run off, estimation of its role in formation of the water quality of the north-western part of the Black Sea. Methods - natural observations, gravimetry, photometry, conductometry. Theoretical and practical results of studies include quantitative estimation of the level of anthropogenic press on the Danube ecosystem, evaluation of the Danube nutrients runoff and other natural and anthropogenic sources in eutrophication of the north-western part of the Black Sea in modern period. The obtained results can be applied in future for prognosis of the development of the eutrophication process and ecological conditions in the north-western part of the Black Sea for a long term period.
