摘要：The regular monitoring of toxic metals in sewage,effluents and vegetables is quite essential to avoid their excessive absorption/consumption in the food chain. The quantification of heavy metals in wastewater (sewage/industrial water),soil and vegetables grown in suburb area (Babu Sabu Toll Plaza) Lahore,Pakistan during 2015-16 have been investigated. These heavy metals include;Pb,Hg,Zn,Cu and Cd. For brief survey,20,20 and 90 samples of sewage water,soil and vegetable,respectively were collected for study. In wastewater,the concentration of heavy metals is observed as Zn > Cu > Cd > Pb,however,Hg was under detection limits. The measured values when compared with WHO standards,these were slightly higher than the safe limits. In soil samples,concentration was observed as Zn > Cu > Pb > Hg > Cd and is in the safe limits. The vegetables were found contaminated with heavy metals exhibiting concentration little higher than permissible limits of WHO/FAO..
