Abstract
The results revealed that the heavy metal content of contaminated soils, such as Pb, Cd and Ni ranged from 10.52 to 84.20 mg kg−1, 73.52 to 184.80 mg kg−1 and 65.88 to 150.68 mg kg−1, respectively. However, in the surrounding villages of contaminated soil areas, all fifty (50 nos.), twenty-one (21 nos.), and twenty-four (24 nos.) samples were noted to cross the maximum permissible limits of Cd, Pb and Ni, respectively. The result revealed that in leafy vegetables collected from contaminated soils, the total content of Cd, Pb and Ni varied widely from 0.66 to 4.54 ppm, 0.22 to 13.32 ppm and 0.06 to 4.20 ppm, respectively, while, 15, 13 and 10 nos. were detected above the prescribed limits of Cd, Pb and Ni, respectively. Heavy metal accumulation in all leafy vegetables with contaminated soils caused a significant increase in all elements like Cd, Pb and Ni. The accumulation trend of metals in all vegetables was Cadmium > Lead > Nickel. Spinach and fenugreek indicated the highest metal absorption capacity compared to other vegetables studied. However, based on WHO standards for heavy metal contamination of soil and accumulation of plants, our data does not ensure safety for human consumption.
