Abstract
This study has been carried out at Lawdar, s tannery (Aden-Yemen), and aimed to determine the mean concentration of seven selected heavy metals (Cr, Fe, Zn, Cu, Pb, Ni, and Ti). four samples (three liquid samples and one solid sample), were analyzed by the ICP-OES technique. The results obtained from this study showed overall mean concentrations of the selected heavy metals in the range of (Cr =0.066 -2.366 mg/L), (Fe=2.230 - 6.519 mg/L), (Zn=4.430 - 42.029 mg/L), (Cu= 0.033 - 3.166 mg/ L), (Pb=0.133 - 0.866 mg/L), (Ni =0.033 - 0.699 mg/L), and (Ti=0.266 - 49.49 mg/L), respectively. The mean concentrations of the selected heavy metals in the wastewater were above the recommended limit.
