A number of minor and trace elements including Be, C, Ca, Cr, K, Li, Mn, Na, P, Pb, S, Tl, V, Zn present in coal fly ash are found to be preferentially concentrated on the particle surfaces. Environmentally effective concentrations these thus much higher than indicated by conventional bulk analyses.
