THE RESULTS OF KUYALNIC ESTUARY HYDROCHEMICAL MONITORING DURING ITS FILLING WITH ODESSA GALF WATER (DECEMBER 2014 — MARCH 2015)

As part of hydrochemical monitoring of Kuyalnic estuary in the initial period of its filling by the Odessa Bay water (December 2014 – May 2015) chemical analysis of samples of sea water, brine, and estuary peloids on the content of a number of basic toxicants: toxic element ions, aromatic polycyclic hydrocarbons, certain pesticides was carrid out . It is shown that contents of practically all inorganic and organic contaminants in Kuyalnic estuary brine are higher than in sea water, so its flowing into the estuary does not lead to an increasing of the basic toxicants content. It was found that with filling of Kuyainic estuary by sea water the probability of precipitation of the hard soluble calcium sulfate (gypsum) is sharply reduced. The results obtained confirm the preliminary conclusions (based on the model experiments) about the ecological safety (chemical terms) of the estuary filling by sea water.
