Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [ 2 ]
Bioremediation broadly refers to any process wherein a biological system (typically bacteria, microalgae, fungi in mycoremediation, and plants in phytoremediation), living or dead, is employed for removing environmental pollutants from air, water, soil, flue gasses, industrial effluents etc., in natural or artificial settings. [1]
Phytoremediation is a process in which plants are used to sequester toxins and hydrocarbons into plant tissue from contaminated soils. The main mechanisms for phytoremediation stem from complex relationships between roots and rhizobia .
Phytoremediation is the use of plant-based technologies to decontaminate an area. Most land plants can form a symbiotic relationship with fungi which is advantageous for both organisms. This relationship is called mycorrhiza. Researchers found that phytoremediation is enhanced by mycorrhizae. [46]
Rhizofiltration is a type of phytoremediation, which refers to the approach of using hydroponically cultivated plant roots to remediate contaminated water through absorption, concentration, and precipitation of pollutants. It also filters through water and dirt. [citation needed]
Phytoextraction is a subprocess of phytoremediation in which plants remove dangerous elements or compounds from soil or water, most usually heavy metals, metals that have a high density and may be toxic to organisms even at relatively low concentrations. [1]
Phytoremediation is an environmentally sustainable process where plants potentially able to break down or sequester, or stimulate micro-organisms in the soil to break down or sequester, certain organic pollutants and inorganic pollutants such as nickel in degraded ecosystems.
Phytoremediation through phytoextraction by a hyperaccumulator; zinc and copper are moved from the soil to the leaves of the plant. Phytomining, sometimes called agromining, [1] is the concept of extracting heavy metals from the soil using plants. [2] Specifically, phytomining is for the purpose of economic gain. [3]
