Assessment of particle size distribution of suspensions in snow of Sikhote-Alin biosphere reserve and nearby settlement Terney

Article is devoted to research the atmospheric suspensions of Sikhote-Alin biospheric reserve and nearby settlement - the settlement of city type Terney by means of laser granulometry methods. It is shown that the volume fraction of microparticles in the reserve makes less than 10 microns in samples from 19,7 to 36,7%, and in the settlement of Terney - from 20,6% to 28,7%. In independence of structure of these particles they constitute potential ecological danger. It is shown that the share of large particles in the reserve and Terney makes from 23,2% to 73,2%. The conclusion is drawn that granulometric profile of suspensions of the reserve corresponds to a profile of suspensions of the Terney settlement. It testifies to presence of the powerful geographical factors defining character of suspensions in this area.
