Abstract
Urbanization acceleration along with advancement of industrial production in the recent years has led to a dramatic augmentation in heavy metal pollutants, harming utmost the ecological environment. There are global concerns of heavy alloy contamination in soils, thereby a greater requirement for soil indemnification. The accumulation along with leaching of heavy ores and metalloids, namely, arsenic, lead, cadmium, and mercury in soil is an issue of growing concern for their lethal, carcinogenic, and mutagenic effects corroborated with multiple organ failure in the living organisms. Contaminated soil leads to multiple physiochemical and biochemical changes ensuing in decreased growth of plants, affecting the yield, and thus, food unavailability. Biochar has been widely reported as an immobilizing agent for the heavy metals in contaminated soils aiding in soil remediation. This chapter furnishes an insight on the native properties of biochar, making it as a choice of adsorbent toward heavy metal remediation from soil.
