The average (n = 40) total fractions of HCl-extractable metals in the O horizon were Cu 46%, Ni 23%, Pb 48%, and Zn 34%; in the A horizon, these were Cu 20%, Ni 5%, Pb 22%, and Zn 5%. Thus, the fraction of HCl-extractable metal depends on the horizon, specifically to the concentrations of organic matter and metals (Pb > Cu > Zn > Ni).
