Abstract
Fly ash and bottom ash materials were filtered from the aqueous effluents of municipal incinerators and from an incinerator-residue processing plant and were examined for ore-grade quantities of metals and for trace metals pollution potential. Several elements, for example ag, al, cu, and ti, are present in concentrations comparable with low-grade ores presently being mined. Elements such as ag, as, cd, cr, cu, hg, pb, sb, sn, and zn are one to three orders of magnitude more enriched in incinerator ash than they are in average crustal abundances. The fly ash and bottom ash materials filtered from incinerator effluents were found to be similar in relative metal concentrations. Incinerator fly ash is one order of magnitude more enriched in ag, cd, ni, pb, sb, and zn than coal fly ash. No significant elemental concentration differences were observed for samples taken during different time periods and from different geographic locations.
