NEET BIOLOGY

Detailed explanation-1: -Phytovolatilization. Phytovolatilization is a phytoremediation strategy using plants to take up pollutants from soil, convert these toxic elements into less toxic volatile form, and subsequently release them into the atmosphere by plant transpiration process via the leaves or foliage system.

Detailed explanation-2: -Phytoremediation basically refers to the use of plants and associated soil microbes to reduce the concentrations or toxic effects of contaminants in the environment. Phytoremediation is widely accepted as a cost-effective environmental restoration technology.

Detailed explanation-3: -Phytoremediation, also referred as botanical bioremediation (Chaney et al., 1997), involves the use of green plants to decontaminate soils, water and air. It is an emerging technology that can be applied to both organic and inorganic pollutants present in the soil, water or air (Salt et al., 1998).

Detailed explanation-4: -Removing arsenic with ferns is just one example of phytoremediation, using plants to purify land or water. By putting plants to work, remediation practitioners can save money on excavation costs and preserve soil structure.

Detailed explanation-5: -PHYTODEGRADATION-The plants absorb hydrocarbons and other complex organic molecules, then metabolize or mineralize them in chemical reactions energized by sunlight. Example: Some enzymes break down ammunition wastes (explosives), chlorinated solvents or herbicides.
