THE EFFECTS OF TRICHLOROETHYLENE ON HEART DEVELOPMENT
Trichloroethylene (TCE; TRI; C2HCl3) is an organic solvent used as an industrial degreasing agent. Due to its widespread use and volatile nature, TCE is a common environmental contaminant. Trichloroethylene exposure has been implicated in the etiology of heart defects in human populations and …

An Exploratory Study of the Systemic Effects of Lead, Trichloroethylene, and a Mixture of Lead and Trichloroethylene Provided Concurrently by Oral Gavage to Male Rats
… dosed with corn oil, corn oil and 2,000 mg/kg trichloroethylene (TCE), corn oil and 2,000 mg/kg lead carbonate, or a mixture of 2,000 mg/kg each TCE and lead carbonate, in an effort to determine whether or not dual administration of both TCE and lead would have an additive effect on …

Reaction Rates For The Dehalogenation Of Trichloroethylene Using Various Types Of Zero-valent Iron
Remediation of trichloroethylene (TCE) and other chlorinated solvents is of great concern due to their toxicity and their persistence in the environment. Iron has been used extensively in the past decade as a subsurface reactive agent for the remediation of dense, nonaqueous-phase liquids (DNAPLs). …

Simulating Remediation of Trichloroethylene in Fractured Bedrock by Thermal Conductive Heating Using the Numerical Model TMVOC
… this time, the subsurface was contaminated with trichloroethylene (TCE) which was a common solvent used at the facility. The pilot test consisted of 15 heater/extraction wells installed to a depth of 16.8 m in weathered mudstone and operated for 102 days. Rock core samples were taken pre- and …

Spatial Relationship between the Trichloroethylene Degrading Bacteria Dehalococcoides Sp., Sulfate Reducers and Archaea during Reductive Dechlorination
Trichloroethylene (TCE) released to the environment is of great concern due to its toxicity and carcinogencity. The microorganisms involved in bioremediation of TCE such as methanogens (organisms within the domain Archaea), sulfate reducing bacteria (SRB) and Dehalococcoides sp. (DHC) are of …

Bioremediation of Trichloroethylene: Analysis of the Plant Gene Response to TCE and Characterization of a Novel TCE-Degrading Endophyte
Trichloroethylene is a common environmental contaminant. High levels of TCE have the potential to cause liver damage and malfunctions in the central nervous system, and it is considered a likely human carcinogen. More than 54% of Superfund sites in the United States are contaminated with TCE. This …

Modeling biotic and abiotic decay of trichloroethylene (TCE) using the Reactive Multi-Species Transport in 3-Dimensional Groundwater Aquifers (RT3D) code
… dense non aqueous phase liquids, DNAPLS, such as trichloroethylene, TCE, is vital to improving the health of groundwater systems. TCE contamination of groundwater systems is of significant concern and its removal a significant challenge. One of the main causes of delays in cleanup of a TCE …

A comparison of the effects of xenobiotics on hepatic haem metabolism
… anaesthetic agents, fluroxene, halothane and trichloroethylene. During the preparation of this thesis, several other chemicals have been found which destroy cytochrome P-450 and affect hepatic haem metabolism (e.g. norethisterone, morphine). In addition to the above, it has been attempted to …

Potential use of ultrasound in chemical monitoring
… of carbon tetrachloride, chloroform, and trichloroethylene after one minute sonication. The increases of Cl{dollar}\sp-{dollar} were accompanied by increases in conductivity and decreases of pH. Ion chromatography of solutions before and after sonication showed that formate ion was also …

Modeling and Data Analysis of Conductive Polymer Composite Sensors
… and at various vapor pressures of toluene and trichloroethylene. Three parameters in the conductivity model were determined by fitting the experimental data. It was shown that by applying this model, the sensor responses can be predicted if the vapor pressure is known; furthermore the vapor …
