Summary
The Tyumen region is an intensively developing region with a high anthropogenic load. The rates of industrial growth affect the increase in the level of pollution of water bodies in the South of the Tyumen Region. The total volume of wastewater discharged by the 80 largest enterprises in the region is about 350 million m3 annually, out of which 237.62 million m3 are treated as standard, which is less than 68%. The total amount of pollutants entering the water bodies exceeds 20 thousand tons per year [Government of the Tyumen region, 2018]. Among the heavy metal ions found in water bodies of the Tyumen region, lead, cadmium, copper, zinc, mercury, nickel and titanium [Petukhov 2017, Guzeeva 2014] prevail in the concentrations exceeding the sanitary-hygienic standards [Сhief state sanitary doctor of the russian federation, 2017] (Fig. 2.)
