RATIONALE OF KUYALNIK ESTUARY FILLING ENVIRONMENTAL SAFETY BY THE BLACK SEA WATERS. CHEMICAL ASPECTS

Abstract

It was found that currently sulphate and calcium ions content in Kuyalnik brine close to the solubility product of CaSO4. If brine will not by dilute precipitation of gypsum may be expect in prospectstive. It is shown that the dilution of the Kuyalnik brine by seawater willreduces the concentration of calcium and sulfate ions reducing their solubility product and making it impossible the formation of calcium sulfate and precipitation of gypsum. On the basis of established the contents of some heavy metals, polyarenes, chlorinated pesticides and polychlorinated biphenyls which were in water and sediments of the Gulf of Odessa , brine and peloids Kuyalnik estuary pronounced more pollution by priority toxicants of estuary compared with seawater. Concluded tht environmental safety of Kuyalnik estuary filling by the Black Sea waters.
