Diffusive‐dispersive processes are ubiquitous in porous media with important implications for solute transport in many natural and engineered systems; however, their effects on isotope fractionation of organic contaminants in subsurface flow‐through ...

This article reviews the current developments in genus Dehalococcoides as key dechlorinating bacteria in chlorinated ethene contaminated sites. The presence of chlorinated ethenes in environment had been a concern for more than five decades as it ...

Can or cannot green rust reduce chlorinated ethenes? [PDF]
Green rusts (GRs) are Fe 2+ , Fe 3+ layered double hydroxides that are widely investigated for the reduction of inorganic and organic pollutants in soils and groundwaters. Of particular interest is the use of GRs for the reduction of chlorinated ethenes, but existing literature shows contrasting results.

Bioremediation of tetra-and trichloroethene-contaminated aquifers is frequently hampered due to incomplete dechlorination to the more toxic dichloroethene (DCE) and vinyl chloride (VC), indicating insufficient knowledge about the biological mechanisms ...

Identification of abiotic and biotic reductive dechlorination in a chlorinated ethene plume after thermal source remediation by means of isotopic and molecular biology tools [PDF]
Thermal tetrachloroethene (PCE) remediation by steam injection in a sandy aquifer led to the release of dissolved organic carbon (DOC) from aquifer sediments resulting in more reduced redox conditions, accelerated PCE biodegradation, and changes in ...

Heat-Activated Persulfate Oxidation of Chlorinated Solvents in Sandy Soil
Heat-activated persulfate oxidative treatment of chlorinated organic solvents containing chlorinated ethenes and ethanes in soil was investigated with different persulfate dosages (20 g/L, 40 g/L, and 60 g/L) and different temperatures (30°C, 40°C, and ...

Abiotic degradation of chlorinated ethanes and ethenes in water [PDF]
Chlorinated ethanes and ethenes are among the most frequently detected organic pollutants of water. Their physicochemical properties are such that they can contaminate aquifers for decades. In favourable conditions, they can undergo degradation. In anaerobic conditions, chlorinated solvents can undergo reductive dechlorination.Abiotic dechlorination is

Multiple Dual C−Cl Isotope Patterns Associated with Reductive Dechlorination of Tetrachloroethene [PDF]
Dual isotope slopes are increasingly used to identify transformation pathways of contaminants. We investigated if reductive dechlorination of tetrachloroethene (PCE) by consortia containing bacteria with different reductive dehalogenases (rdhA) genes can

Temperature is a key factor affecting microbial activity and ecology. An increase in temperature generally increases rates of microbial processes up to a certain threshold, above which rates decline rapidly.

Advanced physicochemical and chemical absorption methods for chlorinated ethenes are feasible but incur high costs and leave traces of pollutants on the site.
