Synergistic Zerovalent Iron (Fe0) and Microbiological Trichloroethene and Perchlorate Reductions Are Determined by the Concentration and Speciation of Fe.

Environmental Science and Technology, 2020
Trichloroethene (TCE) and perchlorate (ClO4-) are cocontaminants at multiple Superfund sites. Fe0 is often used during TCE bioremediation with Dehalococcoides mccartyi to establish anoxic conditions in the aquifer.

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 ...

Chemical reduction of hexavalent chromium (VI) in soil slurry by nano zero valent iron [PDF]

, 2015
The increasing industrial development of recent decades has lead to the production of increasing quantities of waste containing heavy metals, elements often harmful to the environment, which in the past were not properly disposed of, thus inducing soil

Geochemical and microbial community determinants of reductive dechlorination at a site biostimulated with glycerol [PDF]

, 2016
Biostimulation is widely used to enhance reductive dechlorination of chlorinated ethenes in contaminated aquifers. However, the knowledge on corresponding biogeochemical responses is limited. In this study glycerol was injected in an aquifer contaminated

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

Groundwater Monitoring &Remediation, EarlyView.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

Increasing concentrations of dichloromethane, CH2Cl2, inferred from CARIBIC air samples collected 1998–2012 [PDF]

, 2015
Atmospheric concentrations of dichloromethane, CH2Cl2, a regulated toxic air pollutant and minor contributor to stratospheric ozone depletion, were reported to have peaked around 1990 and to be declining in the early part of the 21st century.

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

Groundwater Monitoring &Remediation, EarlyView.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Environmental Exposures and Autoimmune Diseases: Contribution of Gut Microbiome

Frontiers in Immunology, 2020
Environmental agents have been gaining more attention in recent years for their role in the pathogenesis of autoimmune diseases (ADs). Increasing evidence has linked environmental exposures, including trichloroethene (TCE), silica, mercury, pristane ...
