Abstract
Abstract. The purpose of our work was to assess the chemical composition and physicochemical properties of surface water bodies exposed to industrial enterprises and located in close proximity to agricultural land. The environmental condition of industrial regions is determined by the specifics of their development. Recently, vast territories of cities and agricultural lands have been subjected to a high degree of technogenic pollution, which is caused by excessive concentration of production and its continuous and long-term negative impact on natural complexes, which causes a sharp reduction in natural resource potential and its degradation [1, p. 200]. Methods. The article examined the ecological status of flowing water bodies in some areas of the Sverdlovsk region. Assessment of the ecological state of the rivers was assessed by physicochemical and chemical indicators, which included mineralization, hydrogen, and the concentration of salts of heavy metals. Results. During the study, we took water samples from 5 rivers flowing in areas with different technogenic loads. In the hot study, violations were identified by physico-chemical and chemical indicators. At the same time, excesses in mineralization were noted in the rivers of the Artinskiy district, indicators here ranged from 335, which refers to the average mineralization group up to 509 mg/dm3, which refers the river to the group of mineralization increased, almost all the rivers under study have a neutral reaction in terms of hydrogen value. The excess of MPC was noted in the rivers mainly cobalt, manganese, copper, nickel, lead and zinc, while the excess for various metals ranged from 1 to 32 MPC. Scientific novelty. As a result of the study, the most polluted of the rivers studied by us was determined, which is located in the zone of increased technogenic load and it is noted that the maximum concentration of pollutants falls on the Kamenskiy district.
