Public environmental monitoring of the quality of water bodies in Norilsk and Taimyr

Abstract

The problem of environmental pollution and degradation of all elements of ecosystems is becoming more and more urgent. Therefore, the main purpose of the work is to monitor the quality of water bodies. The objects of the research were Norilsk, Kayerkan, Talnakh, Dudinka, and Lama Lake. The study was conducted in August-September 2019. The work investigated the organoleptic characteristics of water bodies: Smell, color, turbidity, salt content, pH, alkalinity, hardness, SO42-, COD. Organoleptic, visual, potentiometric, titrimetric methods were used as research methods. The work identified the causes of odor, turbidity, the color of the water; an evaluation scale for determining organoleptic indicators is given. The color of the water was determined by comparing samples of the test liquid with solutions that imitate the color of natural water. The categories of water salinity are revealed. It was found that the hardness and odor of the water samples did not exceed the norm. The acidic pH is highest on the Ambarnaya River at two sampling points and also on the Daldykan River. It was concluded that the ecological situation in the region requires the adoption of serious measures since the level of pollution of water bodies in many respects exceeds the norm.
