In work the first results of research the dimensional structure of sea suspensions in Uglovoy gulf (Sea of Japan) by means of laser granulometry are given. It is shown that granulometric structure of suspensions particles in Uglovoy gulf was in the range from 0,6 to 1000 microns and averaged 252,5 microns. It is shown that in selection points near which there are drains of the industrial enterprises for east coast, smaller particles (from 6,2 to 28,1 microns) with big surface area, than on the average on the gulf are observed.

Article is devoted to research the atmospheric suspensions at small cities and settlements of the Far East with the population up to 100 thousand people: Magadan, Belogorsk, Partizansk, Solovyevsk, Orotukan by means of laser granulometry and scanning electronic microscopy methods. It is shown that the studied settlements, considering the dimension of atmospheric suspensions fractions and their morphometric characteristics, it is possible to place in the following order on extent of potential health hazard increase: Orotukan, Solovyevsk, Partizansk, Belogorsk, Magadan.

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.
