ECOLOGICAL ESTIMATION OF WATER QUALITY ON HYDROCHEMICAL INDEXES IN ZHAPOROZHIAN RESERVOIR
On the basis of analysis of seasonal dynamics of the most important hydrochemical indexes, which satisfied to the renewal possibilities of water ekosystem, the considerable exceeding of permissible norms was found out on the phosphate contents and values of permanganic oxidation in water of the Zaporozhian Reservoir near industrial center of Dnepropetrovsk. Concentrations of nitrogenic components were found at the permissible level with account of their natural seasonal variations. On the whole, the ecological estimation of water quality in the Zaporozhian Reservoir on basic hydrochemical indexes allows to deliver it to the III class, 5 category (moderately contaminated water).
