Ash samples were collected from a dumping site (fly ash) and an electronic precipitator (ESP) of a 640MW thermal power station for characterization. Analysis of ash sample showed that the major matrix elements in fly ash were Si and Al together with significant percentage of K, Fe, Ca, and Mg. Some of the biologically toxic elements Ni, Cr, Pb, B, and Mo, were also present in substantial amounts. The saturation moisture percentages of both ashes were higher, but bulk density lower, than the normal cultivated soils.
