The accumulating ability of leaves and needles of woody plant leaves and needles in regard to sulfur- and nitrogen-containing impurities in zone and of prevailing influence of industrial emissions is studied in this work; the obtained data were compared with the model calculations of the surface atmosphere layer pollution by sulfur- and nitrogen-containing impurities and chemical analyses of snow tests on the investigation platforms of observation (PO). The results of general sulfur content in leaves and needles of studied plants showed their high convergence with birch-tree show pollution by sulfates on PO 1-PO 5 ((r=0,47, at n=54, p <0,05). The exception is the more distant PO 6, where the minimal values of general sulfur content in plants samples correspond to maximal values of sulfates content in snow that can be connected with winter work of stationary boilers and rocket mass heaters of private houses at neigh bouring of the PO 6 territory. The curves of nitrates containing values in snow and index of atmosphere pollution by nitrogen-containing impurities on the investigating PO have rather expressed convergence. The analysis of phytimonitoring data showed high correspondence of the results by content of general nitrogen in needles of Siberian spruce with index of atmosphere pollution by nitrogen-containing impurities (r=0,47 at n=54, p <0,05) and nitrates-containing in snow. The phytomonitoring data and snow tests analyses allow to itemize the information about the character of air pollution and do the ecological prognosis more reliable.
