ASSESSMENT OF MICRODIMENSIONAL POLLUTION OF THE ATMOSPHERE OF YEKATERINBURG ACCORDING TO THE ANALYSIS OF SNOW COVER

Abstract

The paper is devoted to the research of an atmospheric suspension of Yekaterinburg by means of methods of a laser granulometry and mass spectrometry of high resolution. It is shown that large highways and combined heat and power plant have the most expressed impact on structure of suspensions. In all points of selection particles of the sizes potentially hazardous to health of the person, less than 10 microns, have been found. Around a large highway junction there was revealed the concentration of such particles in the proportion of 43.2%, and around combined heat and power plant the proportion was 45.5%. The mass and spectrometer analysis of snow water showed average concentration of the main heavy metals (Al, Cr, Mn, Fe, Ni, Cu, Zn, Cd, Ba, Pb, As).
