An innovative method for soil vapor extraction to improve extraction and tail gas treatment efficiency

open access: yesScientific Reports, 2022
This study aims to improve soil vapor extraction (SVE) to address its shortcomings in treating halogenated hydrocarbon-contaminated soil. Indoor simulation experiments based on SVE were conducted to provide technical guidance for the remediation of 1,2 ...

Halogenated hydrocarbons in the atmosphere

open access: yesEcotoxicology and Environmental Safety, 1977
The sources, sinks, and tropospheric abundancies of the gaseous halocarbons, so far as they are known, are listed and discussed. The relative importance of natural and of man-made halocarbons is discussed within the context of contemporary concern about the depletion of stratospheric ozone by chlorine-bearing compounds.

C2-C10 hydrocarbon emissions from a boreal wetland and forest floor [PDF]

open access: yesBiogeosciences, 2006
Emissions of various C2-C10 hydrocarbons (VOCs) and halogenated hydrocarbons (VHOCs) from a boreal wetland and a Scots pine forest floor in south-western Finland were measured by the static chamber technique. Isoprene was the main non-methane hydrocarbon

Stage-dependent molecular transformation of DOM during Vallisneria natans decomposition affects DBP formation potential

open access: yesWater Research X
The decomposition of submerged plants releases significant dissolved organic matter (DOM) into freshwater, serving as a precursor for potentially toxic disinfection by-products (DBPs) during drinking water chlorination.
