Granulometry of atmospheric suspension of Zeysky State Reserve (Amur region, Russian Federation)

摘要

The paper presents the results of granulometry studying of particles of atmospheric suspension contained in snow samples collected in Zeya state reserve (seasons winter 2013/2014 years). Snow samples collected at 5 stations were revealed to contain the particles the size of less than 10 μm in ecologically insignificant concentrations (up to 4%). Generally, the particles of 3rd (10-50 μm) and 6th (400-700 μm) size classes prevail at all sampling stations. The particles at all sampling stations have relatively small specific surface area - from 401, 87 to 4720, 22 cm~2/cm~3. It is possible to draw an inference that from the point of view of micro size pollution of atmosphere Zeya state reserve is considered to be a territory with farourable conditions.
