Abstract
Heavy metals contribute to the part of earth crust, heavy metals such as Cu, Pb, Cr, and Hg, are non nutritive toxic metals and are environmental pollutants. Agricultural activities through the application of phosphate fertilizers make this toxic metal readily available in the soil, which can leach in the spring aquifer. Even in traces, these elements can pose a sever risk in the environment, and their bio-accumulation in the food chain can cause drastic problem to humans, this is as a result of accumulation of metals in plant parts having secondary metabolites, which is responsible for a particular pharmacological activity.
