In this paper are shown the results of granulometric and material investigation of nano-and micro-particles of atmospheric mist containing in the snow collected in Karakan mining site (Kuzbass) in the winter of 2011-2012. For comparison we have chosen the selection station in the Kuzbass Botanical Garden of Institute of Human Ecology SB RAS. The use of a laser particle analyzer is shown for the study of the qualitative and quantitative composition of the sediment precipitations. The distribution of airborne particles of different sizes and origins in areas with high anthropogenic pressure and the conservation area was detected.
