In this paper the results of granulometric research of particles from the atmospheric suspensions of the snow collected in 5 points of the Nakhodka city district (Primorsky Krai) in the winter of 2012-2013 including a sanitary protection zone of the coal terminal of Vostochny port are given. In all points of selection in the areas close to the coal terminal the concentration of microdimensional particles from 8 to 65% is noted. The surface area of these particles reaches 7312.63 cm 2/cm 3. The material analysis of particles of snow cover in the studied zones of the Nakhodka city district showed the pollution of the atmosphere with microparticles of coal, metals and rare-earth elements, which proves negative influence of the open coal terminal on the nearby settlement.
