CATALYTIC OXIDATION OF TRACE CONCENTRATIONS OF TRICHLOROETHYLENE OVER Cr 2 O 3 AND 5% Cr ON γ-A O

Ikeda, M., Ohtsuji, H., Imamura, T., and Komoike, Y. (1972). Brit. J. industr. Med., 29, 328-333. Urinary excretion of total trichloro-compounds, trichloroethanol, and trichloroacetic acid as a measure of exposure to trichloroethylene and tetrachloroethylene. To investigate the relation between trichloroethylene and tetrachloroethylene concentrations in working environments and metabolite conce...

Trichloroethylene and trichloroethanol were given intraperitoneally to guinea-pigs. Their effects were tested by measuring the threshold current intensity of electrical skin stimulation, the electrical excitability of the motor cerebral cortex, by recording and analysis of the electroencephalogram, and by electrocardiographic examination. The two compounds had similar effects on the nervous sys...

Engineering of hybrid gene clusters between the toluene metabolic tod operon and the biphenyl metabolic bph operon greatly enhanced the rate of biodegradation of trichloroethylene. Escherichia coli cells carrying a hybrid gene cluster composed of todC1 (the gene encoding the large subunit of toluene terminal dioxygenase in Pseudomonas putida F1), bphA2 (the gene encoding the small subunit of bi...

Current evaluation Conclusion from the previous Monograph: Trichloroethylene (TCE) is probably carcinogenic to humans (Group 2A) based on limited evidence in humans for the carcinogenicity of TCE and sufficient evidence in experimental animals for the carcinogenicity of TCE. In making the overall evaluation, the Working Group considered the following evidence: (i) although the hypothesis linkin...

the photocatalytic decomposition of trichloroethylene (tce) and tetrachloroethylene (pce)in water was studied. tce and pce were present in water at very low concentrations of about 15 μg/dm3. thisconcentration level corresponds to the one occasionally occurring in groundwater. results of this researchconfirmed usefulness of the photocatalytic process for successful removal of low-concentrated t...
