The levels of nine trace metals (Fe, Cu, Mn, Zn, Ni, Co, Pb, Cd and Cr) are determined in ground water, collection water tank and spring sources in Taiz city. The results show that among different water samples the average content of Fe, Cu, Mn, Zn, Ni, Co, Pb, Cr and Cd are in the range of 0.001 to 0.182, 0 to 0.088, 0.01 to 0.295, 0 to 0.2, 0 to 0.17, 0 to 0.438, 0 to 0.37, 0 to 0.086 and 0 mg/L respectively. Fe in water samples was slight higher than the permissible limit of 0.1 mg/L according to WHO. Cu in all samples did not exceed the permissible limit of 1 mg/L prescribed by the YSMO and WHO guidelines. From 4 samples are having Mn more than the permissible limit of 0.2 mg/L according to YSMO standard. Zn concentration is less than the permissible limit according to WHO and YSMO standards. Co is not detectable in three samples, there is no guideline for the maximum allowable level of cobalt in drinking water at this time. The concentration of Ni in twelve samples was higher than the permissible limit of 0.02 prescribed by WHO and YSMO standards. 11 samples show concentration of pb more than the permissible limit of 0.05 mg/L prescribed by WHO and YSMO guidelines. Cr element is not detectable in 3 samples and 4 samples have concentration of Cr more than the permissible limit of 0.05 mg/L prescribed by WHO and YSMO standards. Cd is not detectable in all the study samples. The statistical analysis indicated that Fe showed high significant positive correlation with Mn and Cu. Cu showed high significant positive Zn and significant negative correlation with Ni. |
