“…Tetra-, penta-and hexacyclic aromatic sulfur heterocyclic compounds (thia-arenes) were found in aluminium melting facilities where indoor air samples contained 53 components as thia-arenes, with the total concentration in air found to be 12 g m −3 (Becker et al, 1998). As thia-arenes account for 2.5-10% (0.45-3.1% for PCDTs) of PAH emission it is possible to estimate the global emission, because 5.6 g PAH is released per tonne of aluminium produced (Näf et al, 1994).…”

Previous studies of the global sulfur cycle have focused almost exclusively on oxidized species and just a few sulfides. This focus is expanded here to include a wider range of reduced sulfur compounds. Inorganic sulfides tend to be bound into sediments, and sulfates are present both in sediments and the oceans. Sulfur can adopt polymeric forms that include S-S bonds. This review examines the global anthropogenic sources of reduced sulfur, updating emission inventories and widening the consideration of industrial sources. It estimates the anthropogenic fluxes of key sulfides to the atmosphere (units Gg S

“…Hence, one or more separation steps are usually performed in such determinations and it is now common to include mass spectrometry (MS) or tandem mass spectrometry (MS/MS) in the analysis protocol to help resolve non‐separated substances and establish compound identity. For the more volatile PASHs, gas chromatography (GC) is often employed in conjunction with electron ionization (EI) or chemical ionization (CI) MS 1, 4–6. High‐performance liquid chromatography (HPLC), although in normal usage not providing the resolution of capillary GC, is employed for non‐volatile compounds 7–10.…”

Polycyclic aromatic sulfur-containing compounds (PASHs) are commonly found in fossil fuels and are of considerable importance in environmental studies. This work presents detailed studies on the fragmentation patterns of radical cations formed from four representative PASHs, benzo[b]thiophene, dibenzothiophene, 4-methyldibenzothiophene and 4,6-dimethyldibenzothiophene, using tandem atmospheric pressure chemical ionization mass spectrometry (APCI-MS/MS). Understanding these fragmentation patterns can be a useful aid in the analysis of PASHs employing APCI or electron ionization (EI-MS/MS), either alone or in conjunction with liquid or gas chromatography.

“…The aim of this study was therefore to specify concentra tions of individual thiaarenes in workplace air for the first time. The study is based on analytical methods described by the authors and on the recent finding of a large variety of thiaarenes present in the indoor air of an aluminum reduction plant ( , ). Analyses were made in order to achieve thiaarene and PAH profiles according to different work categories.…”

Quantitation of a variety of tetra-, penta-, and hexacyclic aromatic sulfur heterocycles (thiaarenes) in workplace air of an an aluminum reduction plant has been made by help of gas chromatography with atomic emission detection (GC-AED). Personal exposure to those thiaarenes and to polycyclic aromatic hydrocarbons depending on work categories has been evaluated. Summarized concentrations of the thiaarenes investigated have been found to be 0.4−19.0 μg/m3. When using sulfur selective AED, samples could be analyzed without a prior separation of the thiaarenes from the PAH. The present data indicate a contribution of thiaarenes to the overall toxicity of coal tar pitch volatiles in this work environment.
