Determination of Outdoor Air State within and out of Borders of Sanitary Protection Zone of Iron and Steel Enterprise on the Base of Estimation of Indices of Snow Cover State

Abstract

During research were investigated various geochemical indices of snow cover state in the area of Russia midland: gross mass of dust in snow sample, total load of contamination for each studied toxicant, concentration ratio of chemical elements in the dust, captured by snow cover, and coefficient of relative gain of total load for each studied toxicant, total indices of load. There was established that quantitative composition of snow’s solid residue testified about substantial influence of iron and steel enterprise, as well as other sources of contamination, situated at adjacent territory, on elevated content in atmospheric dust of vanadium, chromium, iron and manganese. Concentration of these substances in atmospheric dust as immediately in the area of enterprise, both at a distance from these enterprises, was higher than concentration of dust in background area. For all without distinction 44 samplings plots, situated as in the borders of sanitary protection zone, both out of borders, was determined category “very high pollution level” and by means of integrated load level.
