Phytoremediation of Trichloroethylene (TCE)
نویسنده
چکیده
Trichloroethylene (TCE) is a chlorinated hydrocarbon used as a solvent in many degreasing and dry-cleaning operations. TCE is one of the most widespread contaminants of soil and groundwater in the United States. It can be found at 50% of the Superfund National Priority List cleanup sites managed by the United State Environmental Protection Agency (USEPA). According to the USEPA, TCE is also above action levels in 17% of the groundwater and 16% of the soil at Resource Conservation and Recovery Act sites (Cooke 1999; Schmiedeskamp 1997; Chappell 1998).

Phytoremediation of trichloroethylene with hybrid poplars.
Axenic tumor cultures of poplar cells, clone H11-11, were grown in the presence of [14C]-trichloroethylene (TCE) (uniformly labeled). The cells were capable of metabolizing TCE to produce trichloroethanol, di- and trichloroacetic acid. Some of the carbon from TCE was found in insoluble, nonextractable cell residue, and small amounts were mineralized to [14C]CO2. Poplar cuttings grown in soil an...
متن کاملMetabolism of the soil and groundwater contaminants, ethylene dibromide and trichloroethylene, by the tropical leguminous tree, Leuceana leucocephala.
Ethylene dibromide (EDB; dibromoethane) and trichloroethylene (TCE) are hazardous environmental pollutants. The use of plants to treat polluted sites and groundwater, termed phytoremediation, requires plants that can both effectively remove the pollutant as well as grow in the climatic region of the site. In this paper, we report that the tropical leguminous tree, Leuceana leucocephala var. K63...
متن کاملMass balance studies of volatile chlorinated hydrocarbon phytoremediation.
In field-scale mass balance studies of poplar remediation of carbon tetrachloride (CT), more than 95% of the mass of CT was degraded with all of the CT chlorine accountable as chloride ion accumulation in the soil. Atmospheric loss of CT through leaf transpiration and trunk diffusion was insignificant. These findings are consistent with previously reported uptake and degradation of trichloroeth...
متن کاملThe role of microbial reductive dechlorination of TCE at a phytoremediation site.
In April 1996, a phytoremediation field demonstration site at the Naval Air Station, Fort Worth, Texas, was developed to remediate shallow oxic ground water (< 3.7 m deep) contaminated with chlorinated ethenes. Microbial populations were sampled in February and June 1998. The populations under the newly planted cottonwood trees had not yet matured to an anaerobic community that could dechlorina...

Chlorinated solvents, especially trichloroethylene (TCE), are the most widespread groundwater contaminants in the United States. Existing methods of pumping and treating are expensive and laborious. Phytoremediation, the use of plants for remediation of soil and groundwater pollution, is less expensive and has low maintenance; however, it requires large land areas and there are a limited number...
