The aim of this study was to assess the heavy metal concentration in the wastewater used in irrigation for vegetable production. Seven heavy metals viz., Pb, Cd, Cu, Zn, Ni, Cr and Fe were targeted for the present investigation. Ten sampling sites were selected on thebasis of mass vegetable production.The results showed that the average level of Zn, Cu and Ni (3.78, 0.015 and 0.006 mg/L respectively) were within the permissible limit at all the sampling sites. Chromium was below the detectable limit and the concentration of Fe, Cd and Pb (1.004, 0.042 and 0.239 mg/L respectively) were found above the prescribed limit at all the sampling sites.

Abstract


The aim of this study was to assess the heavy metal concentration in the wastewater used in irrigation for vegetable production. Seven heavy metals viz., Pb, Cd, Cu, Zn, Ni, Cr and Fe were targeted for the present investigation. Ten sampling sites were selected on thebasis of mass vegetable production.The results showed that the average level of Zn, Cu and Ni (3.78, 0.015 and 0.006 mg/L respectively) were within the permissible limit at all the sampling sites. Chromium was below the detectable limit and the concentration of Fe, Cd and Pb (1.004, 0.042 and 0.239 mg/L respectively) were found above the prescribed limit at all the sampling sites.
