TL;DR: In this paper, the extraction of pure hydrogen from the fermentation of household waste by a mixed anaerobic bacterial flora was demonstrated, where simulated household waste (600 g) was fermented in a bioreactor.
Journal ArticleDOI
Quantification of volatile sulfur compounds in complex gaseous matrices by solid-phase microextraction.
TL;DR: Procedures for quantifying nine volatile sulfur compounds found in complex gaseous samples collected at a biogas-production plant and a sewage treatment plant and it was shown that the drying agent, CaCl2, caused no detectable losses of any of the compounds.
Journal ArticleDOI
Trace determination of volatile sulfur compounds by solid-phase microextraction and GC-MS
TL;DR: A method was developed for the simultaneous determination of the following nine volatile sulfur compounds in gas samples: carbon disulfide, carbonyl sulfide, ethyl sulfide," ethyl methyl sulfide", hydrogen sulfide,'' isopropanethiol,'' methanethiol''.
Journal ArticleDOI
Natural Background Levels of Trifluoroacetate in Rain and Snow
TL;DR: This article found that TFA is ubiquitous in precipitation: samples of rain from Ireland and Poland and snow from Canada, Sweden, New Zealand, and East Antarctica contained 1-1100 ng/L, and, studying a firn core drilled in Antarctica, concentrations of 3-56 ng/l were measured in layers formed during the 19th century.
Journal ArticleDOI
Chloro- and Bromoacetates in Natural Archives of Firn from Antarctica
TL;DR: In this article, a firn core was used to investigate the presence of haloacetates in snow that had accumulated over the past 200 years in Dronning Maud Land, Antarctica.
