Abstract:
A comparative study to detect the uptake of toxic metals (Zn, Cr, Fe, Mn, Co, Ni, Cu, Pb and Cd) in spinach (Spinaceae oleraceae) irrigated by drain and tube well water was carried out along Saggian Drain, Lahore. The metal contents of drain water were fairly higher than those of the tube well water. Similar results are evident from the analytical data of root, shoot and leaves of spinach. It was observed that in root, irrigated with drain water, concentration of Zn was 223.00μg/g and that of Pb was 12.00μg/g. while Zn was 25.66μg/g and Pb was 3.00μg/g in roots irrigated with tube well water. In shoot the concentration of Cr was 26.33μg/g and Cu was 34.50μg/g being irrigated with drain water. While the concentration of these metals were lower in shoot irrigated with tube well water. In leaves irrigated with drain water the concentration of Pb was 11.00μg/g while it was 3.33μg/g when irrigated with tube well water. However, the contamination level of edible parts is toxic to human health; its constant consumption may lead to various health disorders.
