Abstract

The idea of our study was to calculate trace element (Pb, Cd, Hg, Cu) emission into the atmosphere from coal combustion. Emission of the heavy metal was calculated using balance method based on the principle of element mass balance during coal firing. Experimental data of element concentration in the coal, slag and fly ash were adopted for this calculation. Also four others methodologies suggested by different authors were utilized for estimation of element emissions from energy coal combustion. Comparison of the different methods of calculation was made. As a result of this study total amounts of atmospheric heavy metal emissions on the territory of former Soviet Union were evaluated. 1 Introduction Last decades more and more attention having been paid to the problem of ecosystem pollution by heavy
