GRANULOMETRY OF ATMOSPHERIC SUSPENSION OF NORSK STATE RESERVE (AMUR REGION, RUSSIAN FEDERATION)

摘要

The paper presents the results of studying of atmospheric suspensions contained in snow samples of Norsk state reserve (seasons 2013/2014 years). The snow samples gathered at 5 areas were revealed to contain particles size of less than 10 μm in ecologically low concentrations (up to 13 %). Generally the particles of 3rd (10-50 μm), 5th( 100-400 μm) and 7th( more700 μm) size classes prevail at all areas. The particles at all screening areas have relatively small area of a specific surface -from 552,95 to 3272,12 cm~2/cm~3.It may be deducted that from the point of view of microsize atmospheric pollution Norsk state reserve belongs to territories with favourable conditions.
