The paper presents the results of particle size distribution analysis of atmospheric particulate matter studied in the snow of several settlements in the Magadan Region (towns Magadan, Susuman, and Omsukchan). The study found a significant content of PM 10 particles in the air of Magadan town (28 to 65.7%), and a general dominance of particles under 50 μm in diameter (PM 50 fraction) - from 44.4 up to 100%. The content of environmentally significant PM 10 particles in the air of smaller settlements of the Magadan region (towns Susuman and Omsukchan) does not exceed 21. 1%. We can conclude that the air in the Magadan town, due to the predominance of PM 10 and PM 50 particles is characterized by a pronounced micro-particles contamination. This level of pollution, in conjunction with the harsh climate of this region, is a constant source of respiratory diseases and a factor in reduction of the quality of life.
