| Реферат: | eng: This paper considers the elemental composition of aerosols which have accumulated in the snow in winter and that of the top soil layer (0-5 cm), birch (Betula pendula Roth.) leaves collected at the end of the vegetative season, and soils in the vicinity of Novosibirsk. The analysis is carried out using the X-ray fluorescence elemental analysis with synchrotron radiation (SR-XRF) method, which helps reveal the existing local aerosol pollution from industrial sources. The main geochemical indicators of aerosol pollution of the Novosibirsk tin smelter (Novosibirskii Olovokombinat) are As, Sn, Tl, Cd, and Pb; those of three Novosibirsk heat power stations TETs-2, -3, and -5 are V, Mn, I, and Ga. It is found that the accumulation of the majority of technogenic elements in the tissues of higher plants depends on the intensity of the pollution, except for the biophilic Cu, Zn, and Mn, the content of which is more regulated by the physiobiological mechanisms of plants. For example, birch leaves are found to have a lower Mn content in the areas of high technogenic pollution, whereas, in ecologically clean areas, the Mn content in plant tissues is observed to increase. Thus, in Siberia, the snow cover and vegetation are the seasonal depositing components of the urban environment that adequately reflect the existing technogenic aerosol pollution. The elemental SR-XRF analysis of snow and plant tissues can be used to carry out a timely and reliable environmental assessment of an urban territory. © 2011 Pleiades Publishing, Ltd.
