ABSTRACT
Arsenic, cadmium, and lead are three non-vital heavy metals that are harmful to the environment, food safety, and the health of both humans and animals whenever present in excessive quantities. Poisonous metals and metalloid soil can be found worldwide. In higher amounts, some may cause neurological and behavioral abnormalities, particularly in children, while others are endocrine disruptors, carcinogens, teratogens, and mutagenic. The prevention, control, and remediation of heavy metal contamination have grown to be a top national priority in light of the real situation with soil pollution in our nation. To eliminate this kind of pollution, a variety of procedures have been used, including chemical, physical, biological, and integrative methods. Using plants and associated soil bacteria, phytoremediation lowers pollutant concentrations or their hazardous effects on the environment. It is a relatively new method that has gained widespread appeal for being an affordable, effective, unique and environment-friendly technique. The distribution of heavy metals in the environment, their sources, and the ecotoxicity they have on the environment are thoroughly explained in this review paper. Some of the procedures for creating heavy metal-free soil by using various soil remediation techniques are also described.
