%X Based on the analyses of the samples of raw coal,fly ash and bottom ash collected from a power plant from the Northern Shanxi,China,the mobility and emission of sulfur and 42 other elements in these samples were studied quantitatively.The results indicated that:Al and 29 other elements were primarily retained in solid combustion residues;As,Be,Cd,Na,Nb,Ni,P,Pb,Sb and Se were only partially retained in solid combustion residues and partially emitted to the atmosphere;Hg,Br and S were primarily emitted to the atmosphere;the volatile degree of the elements are controlled by their occurrence and geochemistry properties etc.;the mean concentrations of S,Hg and Be emitted form the power plant were calculated theoretically and exceed maximum limit of atmosphere environment standard,and more attention should be paid to them.
