STUDY OF THE CONTENT OF COPPER, COBALT AND LEAD IN THE BOTTOM SEDIMENTS OF PONDS IN GOMEL CITY
A number of metal contents in the bottom sediments of water bodies has the following form Cu> Pb> Co. The surface runoff of the city of Gomel affects the ecosystem of the river. Sozh, as evidenced by the increased content of heavy metals in river sediments beyond the city limits in comparison with the site before the adoption of urban wastewater. A high level of contamination of bottom sediments with heavy metals is characteristic of the area below the city and lake. Y-shaped. A low level of pollution is characteristic of Lake Shapor, Lake Small, although water bodies experience significant anthropogenic pressure, as well as for Lake. Volodkino. The background reservoir, which was previously used as a reference, has ceased to be such, since the concentration of some heavy metals in it is higher than in other studied reservoirs experiencing a more significant anthropogenic load. Due to this fact, it is necessary to strengthen monitoring of this water body.
