1991. Health risk assessment of biodegrad- able volatile organic chemicals: a case study of PCE, TCE, DCE and VC. J. Hazardous Materials 27:111-126.Yeh, H. C., & Kastenberg, W. E. (1991). Health risk assessment of biodegradable volatile organic-chemicals: A case-study of PCE, TCE,...
The enriched bacteria after six-month acclimation could dechlorinate PCE completely because no lesser chlorinated ethenes, including TCE, DCE's, and VC were found in the effluent by GC/MS. The steady high PCE and TCE removed rate and microscopic observation of various types of microorganisms ...
摘要:50升溶剂混合物(25%PCE、25%TCE、25%1,1-二氯乙烯(1,1-DCE)和25%氯乙烯(VC)在位于浅层无承压含水层上方的一个地点发生泄漏。在泄漏后1个月、1年和5年的时间序列中,建立了模拟由此产生的羽流的扩散和迁移的平流-扩散模型。在对污染物的含水层条件和性质进行抽水试验和文献综述的基础上,建立...
Calculations are presented of vibration absorption spectra for tetrachloroethene (PCE), trichloroethene (TCE), dichloroethene (DCE) and vinyl chloride (VC)... L Huang,SG Lambrakos,L Massa - 《Multiscale & Multidisciplinary Modeling Experiments & Design》 被引量: 0发表: 2019年 A MBSE Framework...
tetrachloroethene (PCE), trichlorethylene (TCE), dichloroethene (DCE) and vinyl chloride (VC) as well as typical components from the group of chlorinated methane's, i.e. tetrachloromethane (PCM), trichloromethane (TCM) and dichloromethane (DCM), were also made. The determinations were made ...
Field studies (3,4) have shown partial dechlorination of PCE and TCE to DCE isomers and VC. Aerobic dechlorination has not been demonstrated for PCE. However, aerobic biodegradation of the lesser chlorinated compounds may be more favorable. This rationale has provided support for a sequential ane...
Of the halogenated organic compounds in the environment, the chlorinated ethenes, PCE, TCE, -DCE, VC are of importance. was quantified in a large-scale reactor along with the mRNA of its dehalogenase through several feeding cycles. RTm PCR was shown to be an accurate and efficient ...
The original model simulated competition between three H2-utilizing microbial populations (PCE/TCE dechlorinators, DCE/VC dechlorinators, and hydrogenotrophic methanogens) and the fate and transport of seven groundwater solutes (PCE, TCE, DCE, VC, ETH, H2, and CH4), and ...
The increased amount of organic carbon coupled with the anaerobic and reducing conditions promoted the reductive dechlorination of PCE to lesser chlorinated compounds (TCE, DCE, VC, and ethene). The increased rate of attenuation decreased the ratio of PCE to daughter products, and reduced overall ...
In the controls, TCE, cis -1,2-DCE, and VC ware accumulated as intermediates. No dechlorination occurred in soil that was autoclaved and did not receive microbial granules. Methanogenesis was inhibited in the presence of the high initial PCE level (200 mg/kg soil) but not at the low ...
