“…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.

“…With advanced emission control technology, DPM PAHs and inorganic elements emissions have been reduced significantly (Pakbin et al, 2009;Khalek et al, 2011;Hu et al, 2013). Positive relations between diesel sulfur content and inorganic elements emissions, as well as between diesel sulfur content and particle-phase PAHs emissions have been found (Lim et al, 2007;Lu et al, 2012). Significant differences in PAHs emissions were observed under different engine operation conditions (Shah et al, 2005;Riddle et al, 2007).…”

This paper presents chemical characteristics of diesel particulate matter (DPM). A heavy-duty diesel engine was tested in ETC cycle with an engine dynamometer. The DPM was sampled with quartz fiber membrane and organic membrane filter. Quartz fiber membrane was used for total carbon (TC) and particle-phase PAHs (p-PAHs) measurement, while the organic membrane was used for inorganic elements measurement. On the quartz fiber membrane, the total of 15 elements detected were 11% of DPM mass. Ca, Si, Na and Al were the major components, accounted for 79% of the 15 elements mass. On the organic membrane, total carbon (elemental carbon + organic carbon) was 90% of total DPM mass. Threering p-PAHs were the major components (66%) of total p-PAHs mass followed by four-ring (18%) and two-ring (16%). The FLT/(FLT + PYR) ratio was 0.62, indicative of diesel vehicle emissions.
