Thermal power plants (TPP) are considered as one of the major sources of solid particle inputs in the atmosphere within cities. However, little is known about temporal dynamic of dust pollution and radioactive, rare-earth element concentrations in solid particles within fossil fuel TPP. The aim of this study is analysis of long-term observations (2009–2018) of solid particles composition deposited on snow cover within Tomsk GRES-2 with respect to balance of natural gas and coal used. The authors have studied solid residue of snow cover containing atmospheric particle deposits. Element composition of snow solid residue was determined by instrumental neutron activation analysis (28 elements) and atom-adsorption spectroscopy (mercury). It was revealed the dependence of dust load temporal changing from the balance of fossil fuel used, environmental protection measures and amount of snowfalls. The results show the higher concentrations of U, Ba, Zn, La, Tb, Yb and Sm (10…15 times exceeds the background) and Na, Hg, Ta, Ce, As, Sr and Hf (3…9 times exceeds the background) during the monitoring period when coal balance was up to 35 %. These elements make contribution in the moderately hazardous pollution level. Tomsk GRES-2 emissions could be considered as the main source of these elements. It was determined the similar element concentrations in the snow solid residue and fly ash of GRES-2. Some environmental protection measures were suggested to improve the ecology in the studied area
