摘要：We present here the results of a study on the heavy metal accumulation and distribution in severalvarieties of vegetables grown in the Khetri copper mine region. A total of eight varieties of vegetables (Guar, Spinach,Pepper, Ridged gourd, Brinjal, Bottle gourd, Daikon and Lady finger) were collected neighbouring the mine, tailingsand overburden materials, and were analysed for heavy metals (Cu, Zn, Ni, Mn, Fe, Co, Pb and Cd) to understand theimpact of mining on their distribution and variation in the vegetables. Among the heavy metals, Cu concentration in allstudied vegetables is 2 times higher than the permissible limit of Prevention of Food Adulteration (PFA) act andWHO/FAO. Zn concentration also exceeds the PFA limit in some vegetables while Ni, Co, Mn, Fe, Pb and Cd arepresent within the permissible limit of PFA. Compared to other vegetables, the Guar (oil seed) and Spinach (leafyvegetable) are highly contaminated with Cu. The rank order of vegetables according to their decreasing heavy metalabundances is as follows Guar > Spinach > Pepper > Ridged gourd > Brinjal > Bottle gourd > Daikon > Lady’s finger.The results of the present study will help to assess the impact of consumption of heavy metal bearing vegetables onhuman health in the region.
