Investigation of Trace Metals in Vegetables Grown with Industrial Effluents

Fruits and vegetables are the major sources of minerals vitamins, carbohydrates, protein and fiber. Controlled conditions must be provided during harvesting of vegetable and fruit. The reason behind this study was an observation, that untreated industrials water was used for the harvesting of vegetables of vegetables near Korangi Industrial (KIA). Spinach sponge gourd and tomatoes samples were investigated for heavy metals such as Cd, Co, Cr, Cu, Fe, Pb, Hg, Mn, Ni, and Zn. Pb was found to be maximum among all metals investigated in vegetables and tomatoes samples as 242.5, 46.3, 64.8 mg/kg for spinach gourd and tomatoes respectively. Hg was found to be minimum amount among all metals investigated as 0.18, 0.95 and 0.05 mg/kg for spinach, sponge gourd and tomatoes respectively. A distinct variation in concentrations for all metals was observed for the three vegetables. Metals accumulation in soil and vegetables was also studied. Which was found to be maximum for Pb and minimum for Hg.
