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]
For a plant to extract a heavy metal from water or soil, five things need to happen. The metal must dissolve in something the plant roots can absorb. The plant roots must absorb the heavy metal. The plant must chelate the metal to both protect itself and make the metal more mobile (this can also happen before the metal is absorbed).
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]
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.

There are also plants with medicinal properties, like iron-rich fenugreek, tummy-soothing peppermint and the gel produced by the aloe vera plant. And finally, there’s the integral part plants ...
Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [ 5 ] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.
The food is delicious and plant based to help decrease inflammation while still providing nourishment (bonus: this location allows coffee). The wake-up calls are very early, and the hikes are ...
Ground water remediation techniques span biological, chemical, and physical treatment technologies. Most ground water treatment techniques utilize a combination of technologies. Some of the biological treatment techniques include bioaugmentation, bioventing, biosparging, bioslurping, and phytoremediation.
