Abstract
This paper presents the dynamics of principal chemical components of particulate matter in a smoke screen over Novosibirsk and its suburb resulting from forest fires of the Tomsk region and Krasnoyarsk territory. It has been found that the levels of submicron mass concentration of atmospheric aerosol (AA) increased significantly in 2012 as compared to 2010 and 2011. This increase is correlated with the high presence of organic matter in the atmosphere accompanied by the raised acidity and higher concentration of potassium K+ and formiate HCOO– ions. Changes in the element composition of AA are absent.
