Actual decay of tetrachloroethene (PCE) and trichloroethene (TCE) in a highly contaminated shallow groundwater system

Environmental Advances, 2021
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)

Isolation and genomic characterization of a Dehalococcoides strain suggests genomic rearrangement during culture

Scientific Reports, 2017
We have developed and characterized a bacterial consortium that reductively dechlorinates trichloroethene to ethene. Quantitative PCR analysis for the 16S rRNA and reductive dehalogenase genes showed that the consortium is highly enriched with ...

Biotransformation of trichloroethene by pure bacterial cultures

Folia Microbiologica, 2002
From natural samples 11 isolates able to remove trichloroethene (CCl2CHCl) from an aqueous environment were obtained which were capable of cometabolic degradation of CCl2CHCl by an enzyme system for phenol degradation. At an initial CCl2CHCl concentration of 1 mg/L, the resting cells of particular cultures degraded 33-94% CCl2CHCl during 1 d and their ...

Decoupling Fe⁰ Application and Bioaugmentation in Space and Time Enables Microbial Reductive Dechlorination of Trichloroethene to Ethene: Evidence from Soil Columns

, 2023
Fe0 is a powerful chemical reductant with applications for remediation of chlorinated solvents, including tetrachloroethene and trichloroethene. Its utilization efficiency at contaminated sites is limited because most of the electrons from Fe0 are ...

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds

Development of a Vinylated Cyclic Allene: A Fleeting Strained Diene for the Diels–Alder Reaction

Angewandte Chemie, Volume 137, Issue 33, August 11, 2025.
A strain‐promoted Diels–Alder reaction of the vinylated cyclic allene, a highly reactive strained all‐carbon diene, was developed. Activation of the Kobayashi‐type precursor with fluoride ion generated the vinyl cyclic allene, which was trapped by dienophiles to produce decalin derivatives under mild conditions.

In Situ Colloidal Activated Carbon for PFAS Remediation in Groundwater: Principles, Performance Expectations, and Lessons from the First Decade

Groundwater Monitoring &Remediation, Volume 46, Issue 3, Page 124-145, Summer 2026.
Abstract Injectable colloidal activated carbon (CAC) has been commercially used to remediate per and polyfluoroalkyl substances (PFAS) in groundwater since 2016. The basis of the technology is enhanced PFAS retention within the aquifer from engineered increases in aquifer‐matrix sorptivity (“PFAS enhanced retention”), with re‐equilibration from the ...
