Present study was conducted to check the heavy metal content in wheat treated with municipal solid waste, Although municipal solid waste was enriched with organic nutrient, micronutrients, and macro-nutrients, considerable amount of cobalt was also witnessed in municipal solid waste that s why pot experiment was executed. The concentration of cobalt in different parts of wheat (root, shoot, and grain) was analyzed by atomic absorption spectrophotometer (AA-6300 Shimadzu Japan). Highest concentration of cobalt in root, shoot, and grain of wheat was observed in the range of 0.91–1.02 mg/kg, 0.92–1.04 mg/kg, and 0.93–1.00 mg/kg, respectively, under the influence of different fertilizer's used, while in field experiment, level of Co was greater in roots followed by shoots and grain. The metal concentration in wheat grown in field was ranged from 0.67 to 0.72 mg/kg for roots, 0.64 to 0.71 mg/kg for shoots, and 0.66 to 1.71 mg/kg for grains. Concentrations of cobalt were found below the permissible limits suggested by FAO/WHO. Various indices (PLI, BCF, DIM, HRI) were calculated and results showed that PLI was above 1 indicating that metal was causing pollution in treatments while value of BCF, DIM, and HRI was within the permissible range. Higher Co content in wheat may cause damage to the pancreatic cells of animals, cause respiratory problems, and effects their kidney, liver, and lungs, if exposure is for long period through feed.
