Phytoremediation. Posted by Picasa
phytoremediation (remediation using green plants)...... Phytoremediation: novel approaches to cleaning up polluted soils----Phytoremediation is an innovative technology that utilizes the natural properties of plants in engineered systems to remediate hazardous waste sites---The International Journal of Phytoremediation is the first journal devoted to the publication of current laboratory and field research describing the use of plant systems to remediate contaminated environments----Phytoremediation is the use of green plants to remove, contain, or render harmless environmental contaminants. It is a promising technology that addresses clean-up of organic solvents, PCBs, heavy metals, polyaromatic hydrocarbons, explosives and energetics, or nutrients---Phytoremediation combines the Greek word "phyton", (plant), with the Latin word "remediare", (to remedy) to describe a system whereby certain plants, working together with soil organisms, can transform contaminants into harmless and often, valuable forms...Phytoremediation takes advantage of plants' nutrient utilization processes to take in water and nutrients through roots, transpire water through leaves, and act as a transformation system to metabolize organic compounds, such as oil and pesticides. Or they may absorb and bioaccumulate toxic trace elements including the heavy metals, lead, cadmium, and selenium. In some cases, plants contain 1,000 times more metal than the soil in which they grow. Heavy metals are closely related to the elements plants use for growth-----Transgenic Mustard Cleans Up Soils----Genetically modified Indian mustard plants have successfully cleaned up excessive selenium in a California field----In recent years, researchers have discovered that Indian mustard accumulates moderate levels of environmentally important metals---Pollution-Purging Plants: The hytoremediators-Phytoremediation the use of plants to absorb or break down contaminants has been used over the past decade with varying success. Genetic engineering offers the potential to ramp up the slow-growing phytoremediation industry with a new generation of toxin-cleaning super plants. -
