S. Makarenko popup.description2 The quality of surface natural waters of some reservoirs of Sumy region, in particular, the rivers Psel, Oleshnya, Bytytsya, Sviha and Sula were studied by the methods of chemical and physico-chemical analysis. Compliance of natural water quality with environmental standards was carried out on the basis of such measured chemical-analytical indicators as total hardness, chemical oxygen demand, pH, Eh, content of ions NH4+, NO3–, NO2–, PO43–, Cl–, SO42–, F–. In some cases, the content of heavy metal compounds Fe, Mn, Cu, Cr, Pb, Ni in water and bottom sediments was determined. A stable excess of the maximum permissible concentration of phosphates in most of the studied reservoirs has been established. The role of chemical production of phosphate fertilizers in increasing the content of fluorides in soils and surface natural waters around the city of Sumy is determined.  Product Description popup.authors Bilchenko Mykhailo M Kasianenko Hennadii Ya. popup.nrat_date 2021-04-25 Close
