A quick approach is proposed to evaluate the environmental fate of trace el
ements in coal-fired power plants. It is based on the analysis of feed coal
and solid combustion by-products, together with the leachates of the latte
r. The application of this method in a 1050 MW power plant from NE Spain sh
ows that: (1) Ba, Ce, Co, Cs, Cu, Dy, Ga, Ge, La, Lu, Mn, Ni, Rb, Sr, Tb, T
h, Y, Yb, Zn and Zr were retained in the solid wastes; (2) As, B, Be, Cd, C
r, Li, Mo, Pb, Sb, Sn, Ta, Tl, U, V and W were only partially retained in t
he solid wastes; and (3) Hg and Se were primarily emitted to the atmosphere
