The present work aims to underline the implications of soil contamination. Soil is one of the important non renewable natural resources & is most endangered natural resources. Heavy metal contamination refers to the excessive accumulation of toxic heavy metals such as cadmium, arsenic, spiked etc in the soil caused by human activities such as sewage sludge, combustion of fossil fuels, smelter activities etc. Heavy metals like spiked& cadmium exhibit toxic effect towards soil biota by affecting the physiological metabolism of plants as well as Micro Organisms. Presence of heavy metals in aquatic system results in the production of reactive oxygen species (ROS)that is harmful for aquatic organisms. This review proffers possible solution to restore soil by recommending phytoremediation, which is environment friendly,cheap,safe way to clean up the contaminants by the use of plants & their associated microbes. Plants can be used for pollutant stabilization, extraction, degradation, or volatilization. The plant taken here is Leucaena laucocephala (Subabul) & mustard plant. The main objective of the study is to assess the phytoremediation potentialsubabul (Leucaena leucocephala Lam.) of dried seed pod biomass of in remediating Cadmium soil. This paper presents the brief overview of the preparatory, sampling & analytical stages of soil contamination by heavy metals & how to solve this by phytoremediation.
