| Abstract: | Presented are the results of studies of the component composition of atmospheric aerosols in Mongolia for the period of 2005?C2010. It is demonstrated that the local emissions mostly affect the composition of aerosols in industrial cities (Ulan Bator and Sükhbaatar), whereas the distant transport of pollutants and the wind regime of the area, in particular, the dust storms affect in small towns with the undeveloped industry (Baruun-Urt and Sainshand). Revealed is the dependence of the composition and concentration of suspended particles on the meteorological conditions in the research area. High concentrations of aerosols were observed on the days with strong winds and air masses transport from the deserts and industrial areas of China. Low concentrations of ions were observed during periods of calm weather and in case of the air masses transport from the territories of Russia and Kazakhstan. |
