Phenomenological models of chlorinated hydrocarbons

open access: yesChemosphere, 1991
Abstract Using data in the literature we develop phenomenological models of chlorinated hydrocarbon emissions from modular incinerators. These models suggest that pollution prevention (“front end”) measures, and good combustion conditions could lower HCl and dioxin emissions to manageable levels.

Cometabolic degradation mechanism and microbial network response of methanotrophic consortia to chlorinated hydrocarbon solvents

open access: yesEcotoxicology and Environmental Safety, 2022
The cometabolism mechanism of chlorinated hydrocarbon solvents (CHSs) in mixed consortia remains largely unknown. CHS biodegradation characteristics and microbial networks in methanotrophic consortia were studied for the first time.
