Feasibility of bio-remediation as a solution for Lead pollution in soil

Soil is formed from the gradual breaking and weathering of rocks and covers of the landmass of earth as a thin layer. It is a complete ecosystem in itself and its maintenance is of utmost importance for the continuity of life processes of microbes, plants and animals. However, the quality of soil ecosystem is compromised due to increasing human activities resulting in release of pollutants.
