Dynamics of pollutants accumulation in the snow of an urban agglomeration

Snowpack properties allow using snow as a convenient indicator of atmospheric air pollution, precipitation, and eventually soil pollution. There is a high probability of trace elements and organic pollutants accumulation on the snow cover acting as the deposit matrix. In this study, we analyzed the dynamics of the content of metals (Ca, Mn, Fe, Zn, Sr, Pb and Ba) in filtered and unfiltered samples and the content of polyaromatic hydrocarbons (18 basic PAHs) in weekly snow sampling in the city and nearby. The obtained results were collated with the content of the same contaminants in the snow sampled layer by layer at the end of the season (layer thickness was 0.1 m). In result of the study, we concluded that the sampling should be carried out right after the precipitation for the purpose of atmospheric pollution estimation, because most of heavy metals migrate through the snow layers into soil cover and get lost by the end of the season. The organic pollutants, such as PAHs, are also lost. The sampling of snow during the whole season allows identifying the global and local sources of contaminants released into the atmosphere.

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
