Toluene-induced cells of Pseudomonas putida F1 removed trichloroethylene from growth media at a significantly greater initial rate than the methanotroph Methylosinus trichosporium OB3b. With toluene-induced P. putida F1, the initial degradation rate varied linearly with trichloroethylene concentration over the range of 8 to 80 microM (1.05 to 10.5 ppm). At 80 microM (10.5 ppm) trichloroethylene...

A dielectric barrier discharge reactor with inner electrode modified with metal oxides of Ti, Mn and Co has been designed and tested for the oxidation of diluted volatile organic compounds (VOCs) of different nature like toluene, isopropanol and trichloroethylene. It has been observed that at a fixed concentration of VOC, total oxidation of isopropanol is achieved at lower specific input energy...

hich would you prefer to drink—a cup of caffeine or a cup of trichloroethylene? Chances are good that your response was “caffeine.” Caffeine occurs naturally in coffee, tea, and chocolate, and it is added to sodas and other types of drinks and foods. Trichloroethylene, on the other hand, is a solvent used to dissolve grease, and it is also a common ingredient in glues, paint removers, and clean...

Inhalants are distinguished as a class primarily based upon a shared route of administration. Grouping inhalants according to their abuse-related in vivo pharmacological effects using the drug discrimination procedure has the potential to provide a more relevant classification scheme to the research and treatment community. Mice were trained to differentiate the introceptive effects of the tric...

The literature was reviewed to study cases of intoxication with systemic dermatitis associated with exposure to trichloroethylene. The average age of patients in the reports reviewed to date was twenty-nine; these diseases were found in relatively young persons and no difference was found according to gender. Many cases occurred within one month after the onset of exposure to trichloroethylene,...

Rats have been exposed in a closed system to the chlorinated ethylenes vinyl chloride and trichloroethylene and to carbon tetrachloride as a reference compound. Data of uptake of the compounds, of urinary excretion of metabolites, and of exhalation after exposure show that the chlorinated ethylenes are metabolized much faster than carbon tetrachloride, probably due to their common ethylene stru...

Trichloroethylene is an animal carcinogen with limited evidence of carcinogenicity in humans. Cancer incidence between 1968 and 1997 was evaluated in a cohort of 40,049 blue-collar workers in 347 Danish companies with documented trichloroethylene use. Standardized incidence ratios for total cancer were 1.1 (95% confidence interval (CI): 1.04, 1.12) in men and 1.2 (95% CI: 1.14, 1.33) in women. ...

Trichloroethylene-induced hypersensitivity dermatitis is one of the serious occupational health events in China, however, little is known about the clinical features and possible mechanism of this disorder. The objective of the present study was to report some typical trichloroethylene-induced dermatitis patients and investigate their occupational exposure as well as the clinical features. We s...

A novel and simple one step hydrothermal process is used to prepare TiO(2)/WO(3) nanocomposites, in which WO(3) and TiO(2) are present in hexagonal and anatase crystalline forms, respectively, and have enhanced photocatalytic activity towards trichloroethylene degradation in the gas phase.
