SEDIMENTS OF TRIBUTES AND BAYS OF THE IVANKOVSKOE RESERVOIR AS A POSSIBLE SOURCE OF SECONDARY POLLUTION OF THE RESERVOIR WITH HEAVY METALS
G.Yu. Tolkachev, B.I. Korzhenevskiy

While existing in sediments a considerable amount of different pollutants is accumulated. The most danger from the point of view of water quality was always hidden in microelements: Hg, Cd, Zn, Pb, Cu, Cr, Co, Ni, Fe, Mn, As., as well as their blends characterized by high toxicity. Such substances while accumulating in bottom silts can pass back to the water mass under certain circumstances. So, the investigation of migration of heavy metals in "water-sediments " system and obtaining of quality evaluations of the intensiveness of their mass exchange in this system during different seasons of the year is rather actual task from the point of view of environment, as on the basis of such characteristics we can determine the danger of the secondary pollution. As an example research was undertaken at Ivankovo reservoir located on the Volga river, main source of the water supply of the city of Moscow and a territory with technological load. The results of studies of the contamination of sediments with heavy metals and arsenic, estimated by igeo-classes – by the contamination of the sorbs fraction (less than 0.020 mm). The main polluting elements are Zn and Cr, which technogenic load is estimated from moderately dangerous to strong. The picture of pollution of sediments of the Ivankovo reservoir is presented, from which it can be concluded that, despite the large number of sources of pollution, it is not necessary to talk about an excessively dangerous load on water bodies today.
Keywords: sediments, heavy metals, i-geo class, pollution, technogenic pressure, sorption fraction, reservoir.
