Abstract

Heavy metals are considered as the major classes of a contaminant in nature. Heavy metal contamination from fertilizers, metal mining, and industrial activities leads to toxic effects on humans and other organisms. Although the toxic effects of these elements have been recognized for a long time, exposure to these elements continues. The toxic effects induced by them can lead to death in humans. Several advanced strategies have primarily employed to tidy up the surrounding from toxicants; however, most of the strategies are considered as problematic when getting results. The current concerns regarding the contamination due to heavy metal deposition have introduced the novel advanced technologies to detect the presence of them from soil and wastewater. Several plants have been recognized as potent herbs since they are able to absorb these toxicants. The phytoremediation techniques usually uptake the heavy metals from the soil and wastewater and recognized as a well-established approach to remediate the toxic effects induced by them. The plant-based techniques have some advantages over the conventional strategies. Therefore, the present research has focused on the various technologies used to remove the metal pollutants from natural resources especially from water and soil. These affordable and effective technologies are potentially cost-effective and environmental friendly.
