Human health risks indices and assessment of heavy metals bioaccumulation in Radish crop grown on contaminated soils

Abstract
Vegetables are important edible crops that can be a great source of macro and micronutrients. Various toxic metals including those that are in fairly high amount in soil can be readily taken up by vegetables and accumulated in their edible parts, which ultimately affects human health upon consumption. Those affects can be induced both directly and indirectly; one of it is indirect effects is the overall reduction in plants nutrients uptake. The present study was carried out to examine bioaccumulation of potential toxic metals in radish crop grown on Mine contaminated soils. Soil samples were obtained from various mining sites including (Chromite mine (CM), Quartz Mine (QM), Manganese Mine (MM), Soapstone Mine (SSM)) and later brought to the Ornamental Nursery Department of Horticulture, The University of Agriculture Peshawar. The obtained samples were then compared with garden soil in terms of concentration of heavy metals (Cd, Cr, Mn, Pb), and different growth and yield-related parameters were observed for the radish crop. Health Risk Indices (HRI) were also investigated that showed significant impact on human health upon soil contaminations. The study suggests that Radish crop grown on toxic metals contaminated soil can pose serious threats to agricultural production as well as human health concerns.
