Sequential application of electron donors and humic acids for the anaerobic bioremediation of chlorinated aliphatic hydrocarbons.
In situ anaerobic bioremediation of chlorinated solvents such as perchloroethene (PCE) frequently faces the problem of accumulating toxic, lower chlorinated compounds such as dichloroethene (cis-DCE) and vinyl chloride (VC). In the present study, the efficacy of the sequential application of electron donors, supporting reductive dechlorination, and of humic acids, acting as extracellular electr...
متن کاملAnaerobic transformation of chlorinated aliphatic hydrocarbons in a sand aquifer based on spatial chemical distributions
We estimated the distribution of chlorinated aliphatic hydrocarbons (CAHs) from groundwater samples collected along three transects in a sand aquifer. Trichloroethylene (TCE) leaked and contaminated the aquifer probably more than a decade before we collected the measurements. The data show significant concentrations of TCE, cis-1,2dichloroethylene (c-DCE), vinyl chloride (VC), and ethene. We at...
متن کاملConcentrations of individual serum or plasma bile acids in workers exposed to chlorinated aliphatic hydrocarbons.
Individual serum or plasma bile acid concentrations were measured by high performance liquid chromatography in two groups of workers with differing exposures: to hexachlorobutadiene (HCBD) and a mixture of other chlorinated solvents (SOLVENT) in study A; and trichloroethylene (TCE) in study B. Exposures to HCBD and TCE were associated with highly significant increases in a number of individual ...
متن کاملGlucose and Applied Voltage Accelerated p-Nitrophenol Reduction in Biocathode of Bioelectrochemical Systems
p-Nitrophenol (PNP) is common in the wastewater from many chemical industries. In this study, we investigated the effect of initial concentrations of PNP and glucose and applied voltage on PNP reduction in biocathode BESs and open-circuit biocathode BESs (OC-BES). The PNP degradation efficiency of a biocathode BES with 0.5 V (Bioc0.5) reached 99.5 ± 0.8%, which was higher than the degradation e...
متن کاملAccelerated reduction of chlorinated nitroaromatic antibiotic chloramphenicol by biocathode.
Chlorinated nitroaromatic antibiotic chloramphenicol (CAP) is a priority pollutant in wastewaters. A fed-batch bioelectrochemical system (BES) with biocathode with applied voltage of 0.5 V (served as extracellular electron donor) and glucose as intracellular electron donor was applied to reduce CAP to amine product (AMCl2). The biocathode BES converted 87.1 ± 4.2% of 32 mg/L CAP in 4 h, and the...
