Chemical analysis of Cd, Cu, Pb, Ni, Cr, Zn, Mn and Fe. The content of micronutrients (Zn, Mn, Cu and Fe), and potentially toxic heavy metals (Pb, Cd, Cr and Ni), were examined using a reference method. The bioavailable forms of Cd, Cu, Pb, Ni, Cr, Zn, Mn and Fe were extracted from the soil using a 1 mol dm −3 HCl solution.

concentrations of Pb, Cd, Cu, and Zn were also found in the tanning sludge storage sites (Table2). Meanwhile, met-al concentrations in the soil samples collected from differ-ent sites were highly correlated with Cr-Zn (r =0.671, p < 0.01, N = 16) and Cr-Cd (r = 0.673, p < 0.01, N = 16). These significant correlations indicated a site that
