DETERMINATION OF NITRATE CONTENT IN SURFACE WATER OBJECTS

Abstract

Continuous human activity constantly leads to deterioration of water quality and ecological regime of river runoff. Changes in the quality of water with a tendency to constant deterioration are observed in almost all surface sources of water supply in the country. About 2 million tons of pollutants are discharged into water bodies every year, in particular, more than 500 million m3 of polluted untreated water comes from industry. According to the state water monitoring of the State Water Agency, high concentrations of organic compounds, nitrogen and phosphorus compounds, phenols, oil products, heavy metals, etc. are observed.
