Rapid Detection of Plasticizer Migration From UV‐Aged PVC Films by DART‐HRMS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale The migration of phthalate plasticizers from high‐volume polymers, such as poly(vinyl chloride) (PVC), raises significant toxicological concerns, particularly when materials are subjected to aging and environmental stress. As traditional monitoring techniques rely on time‐consuming solvent extraction and chromatographic methods that ...

Impact of Fixed Nitrogen Availability on Dehalococcoides mccartyi Reductive Dechlorination Activity.

Environmental Science and Technology, 2019
Biostimulation to promote reductive dechlorination is widely practiced, but the value of adding an exogenous nitrogen (N) source (e.g., NH4+) during treatment is unclear.

Color and COD Removal From ECF Effluent by Airlift Reactor With Immobilized Lentinus edodes

Chemical Engineering &Technology, Volume 49, Issue 5, May 2026.
Airlift bioreactor treating ECF bleaching effluent with Lentinus edodes immobilized on polystyrene fibers achieved up to 48% color and 41% COD removal. Under optimized aeration (300 mL/min) and HRT (78 h) without glucose, COD removal remained stable for 15 days, supporting a low‐input, enzyme‐driven strategy for pulp‐and‐paper wastewater.

Microbial Communities Associated with Sustained Anaerobic Reductive Dechlorination of α-, β-, γ-, and δ-Hexachlorocyclohexane Isomers to Monochlorobenzene and Benzene

bioRxiv, 2019
Intensive historical and worldwide use of the persistent pesticide technical-grade hexachlorocyclohexane (HCH), composed of the active ingredient γ-HCH (called lindane) along with several other HCH isomers, has led to widespread contamination. We derived

Evaluation of Iron‐Phosphate Glass–Ceramic Waste Form for Electrorefiner Salt Waste Simulant Dechlorinated With Phosphoric Acid

International Journal of Ceramic Engineering &Science, Volume 8, Issue 3, May 2026.
This work investigates the formation of high‐alkali‐iron‐phosphate glass–ceramic waste forms made from the dechlorinated product of a phosphoric acid‐based process. The salt simulant is mixed with H3PO4 to form a slurry, heated, and then the dechlorinated product is vitrified with glass formers to obtain the final waste form. ABSTRACT The importance of

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.

Dithionite promoted microbial dechlorination of hexachlorobenzene while goethite further accelerated abiotic degradation by sulfidation in paddy soil

Ecotoxicology and Environmental Safety, 2023
It is of great scientific and practical importance to explore the mechanisms of accelerated degradation of Hexachlorobenzene (HCB) in soil. Both iron oxide and dithionite may promote the reductive dechlorination of HCB, but their effects on the microbial
