Abstract
Discharging of municipal solid wastes onto land is really widespread in developing nations. The compounds contained in the municipal solid waste cause a harmful consequence to human and environment. Hence, an appraisal of the extent of their local impact is of keen interest to calculate out the pollution they make. Therefore, a pot trial was performed to observe the effect of diverse doses of municipal solid waste on metal uptake by different parts of wheat variety (Miraj-08). The level of metals in various parts of wheat plant was analyzed by atomic absorption spectrophotometer. The results showed that in the samples of soil, the concentrations of heavy metals (mg/kg) ranged from 3.19 to 4.61 for Zn, 2.44 to 3.32 for Co, 2.12 to 3.28 for Cd, 57.51 to 66.65 for Fe. In wheat grains, concentration of metal varied from 0.67 to 1.37 for Zn, 1.32 to 1.72 for Co, 1.16 to 1.79 for Cd and 14.99 to 17.55 mg/kg Fe respectively. The level of Cd in wheat grains was fond above the permissible limit recommended by FAO/WHO. The bioconcentration factor and transfer factor for all metals was less than 1. Pollution load index and enrichment factor For Cd was highest among all metals. The health risk index for the Cd was greater than 1 indicated that municipal waste treated wheat may pose various health risks to consumers. So, there is a dire need to treat municipal solid waste properly before its application on agricultural land.
