Temperature-associated effects on methanogenesis and microbial reductive dechlorination of trichloroethene in contaminated aquifer sediments

Frontiers in Water
BackgroundAquifer thermal energy storage (ATES) is a subsurface technology for urban heating and cooling. However, ATES systems may intersect with legacy groundwater contaminants from past anthropogenic activities.

Modeled Pathways and Fluxes of PCB Dechlorination by Redox Potentials

Dechlorination is one of the main processes for the natural degradation of polychlorinated biphenyls (PCBs) in an anaerobic environment. However, PCB dechlorination pathways and products vary with PCB congeners, types of functional dechlorinating ...

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Dechlorination of waste polyvinyl chloride (PVC) through non-thermal plasma

, 2023
Dechlorination is essential for the chemical recycling of waste polyvinyl chloride (PVC) plastics. This study investigated the use of non-thermal plasma (NTP) for chlorine removal, with a focus on the effects of treatment time and discharge power on ...

Temporal Evolution of Contaminant Mass Discharge: Effect of Source Remediation at Contaminated Sites

Groundwater Monitoring &Remediation, EarlyView.
Abstract Contaminant mass discharge (CMD) is a key metric for evaluating remediation performance at contaminated sites posing a risk to groundwater. This study assesses temporal CMD trends and associated uncertainties using a geostatistical approach at a chlorinated solvent contaminated site following source zone remediation, supported by two decades ...

Detoxification of 1,1,2-trichloroethane to ethene by desulfitobacterium and identification of its functional reductase gene.

PLoS ONE, 2015
1,1,2-trichloroethane (1,1,2-TCA) has become a common groundwater pollutant due to historically extensive utilization, improper disposal, as well as from incomplete dechlorination of 1,1,2,2-tetrachloroethane.

Multi-modal tomography to assess dechlorination treatments of iron-based archaeological artifacts

Heritage Science, 2019
Chloride ions are an important actor in the corrosion of iron-based archaeological artifact. To stop this degradation, excavated objects are subjected to dechlorination treatment. However, there is no guarantee that this will remove all chloride from the

Use of Polycyclic Aromatic Compounds as Electrophotocatalysts in Organic Reactions

Chemistry–Methods, Volume 6, Issue 11, November 2026.
Emerging from the convergence of photoredox catalysis and electrochemistry, electrophotocatalysis is a relatively new and promising synthetic approach in organic chemistry. In this review, the main advantages and the current challenges of this methodology are discussed, while most relevant and late applications of polycyclic aromatic hydrocarbons (PAHs)
