RESEARCH EXPERIENCE OF SNOW COVER IN DUBNA
This paper is dedicated to the study of air pollution sources, based on geochemical condition indicators of the snow cover in Dubna town, Moscow Region. In the studies of 2010 areal snow survey of entire town territory was undertaken; on the basis of total pollution indicator (Zc) and local background values the territorial zoning by pollution level was made. More detailed study was carried out in 2013 in order to determine the impact degree of specific air pollution sources, such as boiler houses and industrial enterprises. Also the total pollution indicator (Zc) and the total load indicator (Zp) were calculated. The research has found that average daily values of dust load and heavy metals fallout are higher in the area of boiler houses and industrial facilities influence than average daily values received in the course of areal survey. As a result, the study revealed the pollution sources with the major contribution to the air pollution.
