Heavy metals are naturally present in the soil at moderate concentrations; increases in their concentrations to toxic level are due to various anthropogenic sources. These high concentrations thus find their way into the plant system through the roots; wash off to surface water and leached into the groundwater. This may lead to poor plants growth, affect soil fertility negatively and its microbial population. Generally, the effects of heavy metals concentrations, whether short or long terms on any environmental media depend on their source, concentration and persistence.
