- Phytoextraction or phytoaccumulation has emerged as a promising technique for soil remediation that can readily absorb heavy metals and purify the soil of its contaminants. Plants have a natural mechanism to take up and store nutrients according to their bioavailability in soil and the plant’s requirement.

Jan 1, 2016 · The more efficient and useful technique is phytoextraction, but is a more difficult process. This technology involves growth of tolerant plants in contaminated soils; the plant takes up large amounts of heavy metals from the soil, depleting it of the target pollutants and translocating them to the aerial parts of the plant (Rafati et al., 2011 ...

Apr 29, 2020 · Therefore, there is a need to develop cost-effective, efficient, and environment-friendly remediation technologies to reclaim heavy metal-contaminated soil. Phytoremediation is a plant-based approach, which involves the use of plants to extract and remove elemental pollutants or lower their bioavailability in soil (Berti and Cunningham, 2000 ...
Oct 15, 2018 · Phytomining The use of plants for the in situ removal of HMs from sub-economic ore bodies, metalliferous soils or from contaminated mine sites with the additional aim of recovering an economic amount of metals from the plants [according to Sheoran et al. (2009)].
Using plants to extract metals from the environment is not a new idea, but the costs of growing, harvesting and transporting metal-rich plant biomass, in addition to the cost of smelting to the base metal, have been prohibitive to the development of metal phytoextraction.
Sep 1, 2022 · Phytostabilization uses the metal-tolerant plants for HM immobilization in contaminated soils thereby, decreasing their bioavailability in the environment (Yan et al., 2020). As a result, they are unable to migrate to groundwater or join the food cycle ( Ali et al., 2013 ).
Rapid industrialization, mine tailings runoff, and agricultural activities are often detrimental to soil health and can distribute hazardous metal(loid)s into the soil environment, with harmful effects on human and ecosystem health.
