“…Tassi et al, 2010, Schwandner et al, 2013. The global emission of all thiophenes was estimated to be 42.7 Gg S a -1 , which can be broken down to 31.5, 3.35 and 7.83 Gg S a -1 for thiophene, BT (including thia-arenes and benzisothiazole) and DBT (including BNTs, naphthothiophenes and various substituted DBTs) respectively (Table 1).…”

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

“…In the last four decades, several studies have reported the presence of halocarbons in volcanic emissions, in most cases interpreted as related to the contribution from air contamination (Frische et al, 2006, and references therein). However, some authors (Isidorov et al, 1990(Isidorov et al, , 1992Schwandner et al, 2004Schwandner et al, , 2013Tassi et al, 2012a) reported geochemical evidences suggesting a volcanogenic source for halocarbons, especially the hydrogenated species (HCFCs), cannot be excluded. In the Solfatara fumaroles, as well as in the soil gases characterized by low air contamination (group A), CFCs and CH 3 Cl were not detected (Tables A1 and A2).…”

“…PAHs are a group of organic compounds that are generated during the incomplete burning of lignite (Liu et al, 2012), fuels (Lu et al, 2012), volcanic eruption (Schwandner et al, 2013), biomass (Sanchis et al, 2014), garbage (Chen et al, 2013), or other organic substances, such as tobacco (Chalbot et al, 2012). PAHs are highly toxic organic compounds that can cause a range of adverse health effects (e.g., cancer, endocrine disruption, reproductive and developmental effects) (Hoyer, 2001;Matsui, 2008;Liao et al, 2011;Wickramasinghe et al, 2012).…”

In Northern Thailand, wildland fire during cold period releases large amounts of smoke and fine particles into the atmosphere. The fine particles include several persistent organic compounds such as PAHs. In this study, PM 2.5 -bound PAH concentrations in the air of nine administrative provinces, namely Chiang-Mai, Chiang-Rai, Nan, Phayao, Mae Hong Son, Phrae, Lampang, Lamphun, Uttaradit (N Thailand) were determined during the wildland fire and non-wildland fire seasons. The monitoring strategy comprised two campaigns in each season. PM 2.5 was collected using MiniVolTM portable air samplers (Airmetrics) with quartz fibre filters. Both PAHs and their B[a]P Equivalent concentrations of other urban cities around the world were significantly higher than those of northern provinces for both seasons. The average cancer risks observed at nine administrative provinces were 8.525 × 10 -4 ± 3.493 × 10 -3 and 2.558 × 10 -3 ± 6.986 × 10 -3 for ingestion rate of 50 and 100 mg day -1 , respectively. The excess cancer risks of world cities for ingestion rate of 50 and 100 mg day -1 were much higher than those of Northern Thailand for 851 and 567 times in that order. Dust ingestion was exceedingly critical to non-dietary PAH exposure in comparison with PM 2.5 inhalation. These results are in good agreement with those of previous studies, underlining the significance of indoor air quality on long-term adverse respiratory diseases in Asian cities.
