Abstract

The water range from Pb (1.439 – 1.715), Cu (0.234 – 0.377), Cd (0.838 – 1.346), Zn (0.448 – 1.110), Cr (0.144 – 0.794), Mn (0.777 – 2.011) and As (0.584 – 1.341) mg/L. The range in soil was Pb (67.5 – 120), Cu (8.51 – 32.5), Cd (0.21 – 1.72), Zn (70.8 – 85.6), Cr (15.8 – 29.5), Mn (14.6 – 19.1) and As (52.0 – 198) mg/kg and in the vegetables in the range of Pb (0.177 – 0.545), Cu (0.073 – 0.748), Cd (0.005 – 0.019), Zn (0.264 – 0.915), Cr (0.089 – 0.158), Mn (0.162 – 0.253) and As (0.032 – 0.245) mg/kg. The study shows that the transfer coefficient of the heavy metals to vegetable was less than one ( Zn > Mn > Cr > Cu > Pb > As. The health risk index (HRI) of all the studied heavy metals indicated that all vegetables were safe with no risk to human health except for Cd. health risk assessment of heavy metals in consumption of vegetables irrigated with tin mine pond water in Jos - South, Plateau State
