Comparative Characteristics of Average Annual Suspended Substances Conception in River Sources of the Khanty-Mansiysk Autonomous Area

About the author:

Abstract:

This article studies the data on water resources quality of Khanty-Mansiysk Autonomous Area. It presents the tables with comparative characteristics of water resources during the period from 2014 to 2017 including 20 chemical pollutants. The author has established the pollutants concentration dependence connected with marshy rivers flooding, mixing of water of rivers and marshes.

This paper provides the location of 26 hydrolic posts (locations of water probes). The evaluation is being conducted in Khanty-Mansiysk Environmental Centre of hydro meteorology, while monitoring — in Ob-Irtysh Management of Environmental Hydro Meteorology and Monitoring. The water quality of the Ob total outflow influences significantly the river water quality of Khanty-Mansiysk Autonomous Area, according to its geographical position.

Distinguishing feature is the exceeded concentrations of iron (in 98% of measurements), manganese and copper (in 60% of measurements). Results of calculations of the whole massive data (40 thousand observations) show that at 95% level of significance into the sum total are included results, not exceeded 0.45 mg/dm³.
