The paper is devoted to the research of an atmospheric suspension of Yekaterinburg by means of methods of a laser granulometry and mass spectrometry of high resolution. It is shown that large highways and combined heat and power plant have the most expressed impact on structure of suspensions. In all points of selection particles of the sizes potentially hazardous to health of the person, less than 10 microns, have been found. Around a large highway junction there was revealed the concentration of such particles in the proportion of 43.2%, and around combined heat and power plant the proportion was 45.5%. The mass and spectrometer analysis of snow water showed average concentration of the main heavy metals (Al, Cr, Mn, Fe, Ni, Cu, Zn, Cd, Ba, Pb, As).

The article is devoted to the research of atmospheric suspensions of settlements of the Primorsky region: Dalnegorsk, Luchegorsk, Rudnaya Pristan by means of laser granulometry and mass spectrometry of high resolution. For control the border zone of the Sikhote-Alinsky Biospheric Reserve has been chosen. In Dalnegorsk and Rudnaya Pristan the prevalence in snow of firm particles up to 10 microns in size from 54 to 100% is recorded. In Dalnegorsk in snow in a water-soluble phase there is a big quantity of Fe, Ni and Cu, and near the enterprise «Bor» of Zn. In a water-soluble phase of the samples which were taken in Rudnaya Pristan, high concentration of Pb was revealed. In Luchegorsk near Regional Power Station microparticles of 10-18 microns in size in the proportion of 72% were found out, and in a water-soluble phase there was a sharp increase of Zn concentration, and moderate increase of Pb, Al and Fe. In two points on border with Sikhote-Alin Biosphere Reserve large firm particles (515.46-954.78 microns) were found and only in one point adjoining a highway there was the prevalence of microparticles (9-20 microns). Also there was high concentration of Zn in one of the points on the border with the reserve. It proves the fact that technogenic factors influence the conservation zone more and more.

The article is devoted to the research of atmospheric suspensions of Petropavlovsk-Kamchatsky by methods of laser granulometry, high resolution mass spectrometry (HR-ICP-MS) and scanning electronic microscopy. It is shown that the sea has the most important impact on the structure of suspensions in all samples there are salt rock and sylvinite in significant amounts. Near a large rotary, nanoparticles (40-120 nanometers) which are the particles of soot and metals (Fe, W, Ti, Co, Ba) were found. Park zones are characterized by large particles (more than 100 microns) which in their composition are minerals, organic detrity and compounds of metals (Fe, Ti, Ba, W, Co, etc.). Around combined heat and power plants (CHHP-1 and CHPP-2), coal, black and metallic (Fe, Ba, W, Ti, Co, V) particles of 10-50 microns in size were found in samples. Thus, the level of air pollution in Petropavlovsk-Kamchatsky is not high; there are more natural components rather than technology-related ones in the air of the city. At the same time findings of a high proportion of metallic and soot nanoparticles in the samples taken from the rotary is of great concern. It is obvious that the more cars there are, more negatively they will influence the health of a person.

In work the results of research the snow cover by methods of laser granulometry and mass spectrometry of high resolution with inductively connected plasma of the largest city in the Far East Vladivostok (the mainland and Russkiy Island) during a winter season of 2013-2014 are given. Tests were selected in 16 points: 13 points Vladivostok, 3 points Russkiy Island (FEFU campus, bridge, Channel settlement). Distribution of Pb, Cr, Mn, Fe, Co, Ni, Cu and Zn and microdimensional particles in the tests of snow which have been selected in Vladivostok districts differing with anthropogenous loading and Russkiy Island is revealed.
