Abstract
In the study site, the mining action goes back to the 14th century. Literature reviews about subject showed that scientific analyses on soil mineralogy and heavy metal pollution of this area was not performed in this process. Therefore, current work was conducted to evaluate the level of heavy metals As, Se Mo, Fe, Cu, Zn, Ni and Pb and to determine the danger to human health through consumption of fenugreek leaves (Trigonellafoenum-graecum) by metals. Heavy metal analysis was performed by atomic absorption spectrophotometer (Z-8200, Japan). Level of heavy metals (in soil and vegetable) were present within the acceptable range except for Mo and Pb. High BCF was observed for Mo (2.07), Fe (6.93), Cu (3.98), and Zn (11.99) at TWI-I as compared to other sites. Highest values of PLI and HRI were found at wastewater irrigated site that exhibited high risk to human health. In conclusion, irrigation with contaminated water has led to contamination of heavy metals in vegetables bringing hazardous effect to consumers.
