CO-driven electron and carbon flux fuels synergistic microbial reductive dechlorination [PDF]
Background Carbon monoxide (CO), hypothetically linked to prebiotic biosynthesis and possibly the origin of the life, emerges as a substantive growth substrate for numerous microorganisms.

The Quaternary shallow aquifer that served as the subject of research in this work is under the influence of strong anthropopressure manifested by extreme values of contamination with both organic and inorganic substances (max. TOC 1.6 g/l and Cl− 10 g/l)

UAV-based sampling systems to analyse greenhouse gases and volatile organic compounds encompassing compound-specific stable isotope analysis [PDF]
The study herein reports on the development and testing of sampling systems (and subsequent analytical setups) that were deployed on an unmanned aerial vehicle (UAV) for the purpose of analysing greenhouse gases (GHGs) and volatile organic compounds ...

Modeling Chlorine Isotope Trends during Sequential Transformation of Chlorinated Ethenes [PDF]
There is increasing interest in combined carbon-chlorine compound-specific isotope analysis (CSIA)to differentiate between contaminant sources and to assess transformation processes. However, the significant abundance of polychlorinated molecules with several heavy chlorine isotopes complicates the evaluation of chlorine isotope trends.

Chlorinated Ethene Source Remediation: Lessons Learned [PDF]
Chlorinated solvents such as trichloroethene (TCE) and tetrachloroethene (PCE) are widespread groundwater contaminants often released as dense nonaqueous phase liquids (DNAPLs). These contaminants are difficult to remediate, particularly their source zones.

Mixed plumes of chlorinated organics and oxidized metals are a common contaminant at many sites. The oxidized metals can be mediated by the establishment of moderately reducing conditions.

Application of in situ chemical oxidation technique with potassium permanganate for the remediation of a shallow aquifer contaminated with chlorinated solvents [PDF]
In situ chemical oxidation is a method that is frequently being used for the remediation of contaminated areas, since it presents an adequate efficiency in the reduction of the contaminant mass, particularly chlorinated ethenes, in a relatively short ...

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 ...
