Surface Water Supply

The article is devoted to the study of the ecological and hydrochemical parameters of rivers Volga and Dubna within Dubna city, Moscow region, while considering both the actual ecological and hydrochemical indicators, as well as the biochemical and ecotoxicological characteristics of watercourses. It is shown that watercourses are constantly subjected to anthropogenic pressure. It inevitably leads to the arrival of a number of pollutants including heavy metals that can destroy the existing ecological balance of reservoirs. Since the Volga is a source of surface water supply for Dubna city, and both rivers are popular in terms of recreational activities and fishing, an urgent issue is to study the nosologies of the urban population caused by the impact of the waters of both rivers. It is shown that the high probability of the potential development of environmental-related nosologies is not currently fixed, the carcinogenic risk to the health of the population of Dubna city has a minimal, low and moderate degree as a result of surface water pollution, the non-carcinogenic danger from surface water pollution has a minimum, permissible and moderate degree of danger. The critical organs and body systems of the population of the territory are primarily the gastrointestinal tract, central nervous, nervous and cardiovascular systems. Attention should be paid to monitoring in surface water bodies such contaminants as magnesium, nitrite, nitrate, and ammonium salts, phosphates, zinc, copper, and lead.

Surface Water Pollution

Regardless of the fact that both urban ecosystems studied – Orhei and Telenești – have purification stations, they are still an essential source of surface water pollution. The aqueous soil extract (Telenești) has a pH value of 8 up to 9.8 due to the high content of calcium and potassium in the soil, due to the fact that the area under investigation has a specific character caused by the spread of solonetz-type soils, solonized chernozems, and salinated soils. The anthropogenic impact in urban ecosystems produces an imbalance in the ratio of spontaneous species and ruderal and ruderal-segetal species. The number of spontaneous species is the indicator of the degree of anthropization in urban ecosystems. Urban ecosystems have a major impact on the environment.
