MARINE SUSPENSIONS ABILITY TO CONCENTRATE MERCURY DEPENDING ON ITS CONTENTS IN THE SHELF WATER AREA
According to the results of measurements of mercury concentration in water samples taken in spring 2012-2017, in the waters of the Crimean shelf of the Black Sea, dependence of the concentration of mercury on suspended matter was determined. The trend is in saturation of suspensions with mercury under increase in its concentration in water. The coefficients of accumulation of mercury by suspensions are determined and it is established that the dependence of the accumulation coefficients on the change in mercury concentration in the water of the Crimean shelf of the Black Sea is described by the Freundlich equation and also with a less degree of reliability by the Langmuir equation. It is determined that the prevailing factor of sedimentation self-purification of water in the low mercury concentration in water is the concentrating ability of suspensions, with the increase in water pollution by mercury, the relative influence of the concentrating ability of suspensions decreases
