Abstract
Heavy metal accumulation in edible parts of plants is major international concern now a day. This research was aimed to observe the influence of different level of municipal solid waste on metal accumulation by wheat variety (Inqalab-91). The metal concentration in soil and wheat grains was quantified using atomic absorption spectrophotometer (AA-6300 Shimadzu Japan). Results demonstrated that municipal solid waste treatment increased the heavy metals in various parts (root, shoot, grains) of wheat plant. The metals in wheat grains varied from 1.5-2.46, 10-18.16, 0.8-0.95 and 0.53-0.95 mg/kg for Cd, Fe, Zn and Co, respectively. The amount of all heavy metals were determined within the permissible range except for Cd. The cadmium had the highest bio concentration and enrichment factor. The pollution load index values for Cd and Co were the highest. The health risk index values for Cd, Fe and Co were ˃ 1 indicating that wheat grains were not suitable for human consumption. So, it is concluded that proper treatment of municipal solid waste is necessary before its application on land.

The current work was performed with objectives: (1) to examine the metal concentration in different parts of wheat plant, (2) to determine bioconcentration factor and transfer factor, (3) to estimate pollution load index, (4) to appraise health risk index
Materials and methods Study area In order to analyse heavy metal content in the wheat (Triticum aestivum L.) using municipal solid waste treatment, a pot experiment was conducted at Department of Botany, University of Sargodha during 2016-2017
Summary
Heavy metal accumulation in edible parts of plants is major international concern a day. Industrial wastes are the chief source of the heavy metals, as they pour their all waste material in running water, lakes and stream and accelerate their amount in the water This untreated water in many countries, used for agriculture purposes [8, 9], it brings very harmful effects on crops and soil. This high concentration of the heavy metals which are present in crops causes very lethal effects to the heath of human and animals through the food chain [10]. The current work was performed with objectives: (1) to examine the metal concentration in different parts of wheat plant, (2) to determine bioconcentration factor and transfer factor, (3) to estimate pollution load index, (4) to appraise health risk index
