The spill pressure of the contaminant source is an important factor affecting amount, location, form, and behavior dense non-aqueous phase liquids (DNAPLs) that plume in a contaminated subsurface environment. In this study, perchloroethylene (PCE) infiltration, distribution and, remediation via surfactant-enhanced aquifer (SEAR) technique for PCE event are simulated to evaluate effects on DNAPL...

Two membrane-bound, reductive dehalogenases that constitute a novel pathway for complete dechlorination of tetrachloroethene (perchloroethylene [PCE]) to ethene were partially purified from an anaerobic microbial enrichment culture containing Dehalococcoides ethenogenes 195. When titanium (III) citrate and methyl viologen were used as reductants, PCE-reductive dehalogenase (PCE-RDase) (51 kDa) ...

The results showed a A recent study demonstrates that dry-cleaners chronicsignificant increase in a number of parameters (urinary ally exposed to perchloroethylene (PCE) show clear excretion of proteins, laminin fragments, glycosaminoevidence for renal damage [1]. PCE is a synthetic glycan, and tubular epithelial brush-border antigen) halogenated hydrocarbon. It is u...

The combined action of substances having a munidirectional toxic effect on the organism was studied for several typical chlorine derivatives of hydrocarbons (1,2-dichloropropane, 1,2,3,-trichloropropane, and perchloroethylene). Since a correct assessment of the combined action of substances is based on the comparison of the effect of mixed compounds and the effects observed for each component a...

Chlorinated aliphatic hydrocarbons and chlorinated aromatic hydrocarbons (CHCs) are toxic and carcinogenic contaminants commonly found in environmental samples, and efficient online detection of these contaminants is still challenging at the present stage. Here, we report an advanced Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR) sensor for in-situ and simultane...
