Heavy metal like Cr, Pb, Cu, Cd, Fe, Ni and Mn were investigated in the medicinal plant Lepidium sativum as well as in their soils using atomic adsorption spectrophotometer. The plant samples were collected from three different areas i.e. polluted, less polluted and non-polluted area of Peshawar situated at distance of 3 and 4 km from the main polluted area. The plant parts including roots, stem, leaves and seeds were found to have more heavy metal than less polluted and non-polluted area. The main purpose of the study was to make awareness among the public about the use of such medicinal plants containing high level of heavy metals and their adverse health affects.
