In the paper, results of a substantial study of nanoand microparticles of atmospheric suspensions contained in snow in winter 2011-2012 in Blagoveshchensk have been presented. Distribution of airborne particles of different origin in 25 areas of sampling differing in anthropogenic loadings has been determined. Large and average-sized traffic centers supply in the atmosphere microparticles of rubber, asphalt and various metals and their oxides (Fe, Ni, Co, Cu, Fe, Bi, W). Railway junctions are a source of microparticles of Fe and soot which get to the atmosphere because of friction of metal surfaces and diesel locomotive engines operation. Parks and suburban districts are a source of microand macroparticles of natural minerals and rocks and of vegetable detritus. It has been shown that composition of atmospheric suspensions of Blagoveshchensk completely corresponded to ecogeographi-cal prerequisites the bank of two large rivers, small impact of enterprises and motor transport, a large railway junction.
