Ecological Systems and Devices Annotation << Back Quantitative estimation of accumulative processes at an artificial reservoir E.I. Shavrak The system of indices has been proposed, allowing to estimate differentially the accumulation of substances both at ground sediment and in soluble state. Accounts of these indices have been realized over a period of 2001–2009 for 16 ingredients of Zymliansk reservoir water. The substances have been identified, modification of whose chemical composition in the territory of the reservoir is most significant. The factors have been stated, that determine the activity of accumulation processes. Key words: artificial reservoir; accumulation; indices; correlations; stress; hydrological.
