Description
Summary: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.
