Objective - monitoring of the forms of inorganic (Pb, Cd, Se, U, Th, V, As, Co) and organic (surfactants, OCPs, PCBs and PAHs) toxicants in aquatic environments and sediments of the Dnieper, the Desna and Dnieper- Buzhske estuary. Investigation of the contamination of water systems, the bioavailability of metals and their evaluation studies toksic. Methods - atomic - absorption spectrometry, gas chromatography - mass spectrometry, high performance liquid chromatography, atomic - emission spectrometry with inductively coupled plasma , photometry. Main results - monitored the level of pollution of rivers of Ukraine toxic metals (TM) Pb, Cd, U, Th, V, Co, nonmetals Se, As and organic toxicants OCPs , PCBs and PAHs, are defined by their content and investigated condition (colloidal, soluble, weighted ) in the Dnieper, the Desna, Western and Southern Bug and Dnieper- Buzhske estuary (Nikolaev). It is shown that Ba, Li, As in the river water are mainly in dissolved form , sorption to suspended particles characteristic of the behavior of trace Se, U, Cd, Mn, Co, their mass fraction is ( 36-97 ) % for Se and U determined mass fraction of colloidal particles ranging in size from 0.20 microns to 0.45 microns, which in some samples is 12 % water and 7.2 %, respectively, assessed their bioavailability. Monitoring the concentrations of these organic compoundso (OCPs , PCBs and PAHs) in natural surface water of different rivers in Ukraine an assessment of the level of contamination of rivers Dnieper, the Desna, Western and Southern Bug specified toxicants. Scope - environmental protection, water treatment and water quality control systems.
