ANNOTATION

The article discusses the results of physicochemical studies on the dynamics of changes in the elements of pollutants in the aquatic environment. The content and concentration of heavy metals, as well as the degree of pollution of the investigated water sources have been determined. The authors note that in an acidic environment, the mobility of lead, chromium and nickel ions increases and the influence of heavy metals increases. The concentration of heavy metals in water increases with increasing pH.

KEY WORDS

hydrochemical characteristics, water systems, heavy metals, water quality, pH
