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 environmentfriendly 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.
