چکیده
Heavy metal contamination of the soil has become a serious problem confronting both scientists and regulators around the world. The occurrence and accumulation of these heavy metals in farm soils has far reaching implications on human health as humans occupy a key position on the food chain. Within the last ten years, studies on heavy metal accumulation in food crops and agricultural soils conducted around the world have revealed a worrisome trend of heavy metal concentrations exceeding maximum permissible limits in food crops and farm soils [1-10].
