“…Regarding the detection limits, the average instrument detection limit (IDL) of the TD-GC/MS method was 0.04 ng and the average method detection limit (MDL), assuming a total sample volume 240 m 3 (30 m 3 ·h −1 for 8 h), was 2.89 × 10 −3 ng·m −3 [ 28 ].…”

Thermal desorption (TD) coupled with gas chromatography/mass spectrometry (TD-GC/MS) is a simple alternative that overcomes the main drawbacks of the solvent extraction-based method: long extraction times, high sample manipulation, and large amounts of solvent waste. This work describes the optimization of TD-GC/MS for the measurement of airborne polycyclic aromatic hydrocarbons (PAHs) in particulate phase. The performance of the method was tested by Standard Reference Material (SRM) 1649b urban dust and compared with the conventional method (Soxhlet extraction-GC/MS), showing a better recovery (mean of 97%), precision (mean of 12%), and accuracy (±25%) for the determination of 14 EPA PAHs. Furthermore, other 15 nonpriority PAHs were identified and quantified using their relative response factors (RRFs). Finally, the proposed method was successfully applied for the quantification of PAHs in real 8 h-samples (PM10), demonstrating its capability for determination of these compounds in short-term monitoring.

“…Bilbao city is the most populated area in the Basque Country and the tenth largest in Spain (approximately 350,000 in the city and 1 million inhabitants in the metropolitan area). In this urban area, local traffic and stationary emissions from the surrounding industries are considered as the major sources of atmospheric pollutants [ 28 ].…”

“…However, TPAH (both 3,4 and 5,6-ring) showed dilution with mixed layer depth. Thus, the meteorology substantially influenced the seasonal variation, especially by diluting the pollutant load during pre-monsoon with higher wind speed, temperature, solar radiation and boundary layer (Elorduy et al, 2016;Wnorowski, 2017). Recently we have observed that the water-soluble ionic components of aerosols in ultrafine and accumulation modes were significantly increased because of transport of pollutants from the Eastern Ghats fire active regions despite the meteorological conditions favorable for the dispersion (Ghosh et al, 2019).…”

The polycyclic aromatic hydrocarbons (PAHs) are considered as an important class of organic pollutants in the urban atmosphere to pose serious health hazards. A comprehensive study was conducted during the dry seasons of 2017-2018 to understand the impacts of local sources, meteorology, boundary layer dynamics, and long-range transport, on the sizespecific particulate PAHs (Coarse: 10-2.1 µm; Superfine: 2.1-1.1 µm; Accumulation: 1.1-0.4 µm and Ultrafine: < 0.4 µm). Samples were collected over Kolkata (22.33°N and 88.20°E), a megacity of the lower Indo-Gangetic Plain (IGP). Wintertime distributions of all PAHs were exclusively unimodal with their maximum abundance in accumulation mode, whereas the 4,5 and 6-ring PAHs showed additional coarse mode peaks during post-monsoon and pre-monsoon. The Concentration Weighted Trajectory model has identified the middle IGP and the Eastern Ghats as the potent PAH source regions for the receptor site. Meteorology significantly influenced, in minimizing the contributions of transported PAHs from biomass burning regions of Eastern Ghats during pre-monsoon. On the contrary, meteorology favored the PAHs accumulation from local emissions and long-range transport during winter and post-monsoon. Source apportionment by positive matrix factorization model identified unburned petroleum, incineration, fossil fuel and coal burning as possible major sources of size-specific PAHs. Additionally, based on benzo(a)pyrene equivalent concentrations, the incremental lifetime cancer risk (ILCR) values were estimated for four human age groups. In general, ILCR values were influenced by the accumulation mode, and they were highest for all size ranges during winter. The estimated upper limit of ILCR (9.26 × 10-6) exceeding the carcinogenic benchmark level (1 × 10-6), draws attention towards the adverse impacts of wintertime ultrafine PAHs on human health in Kolkata, where poor air quality is already a major concern.

“…Polar, thermolabile and weakly volatile compounds cannot be analyzed by thermal extraction. To the best of our knowledge, this technique has never been reported for the simultaneous determination of a large panel of SVOCs in indoor settled dust, but has already been used to measure polycyclic aromatic hydrocarbons (PAHs) [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] and many other SVOCs [37][38][39] in airborne particulate matter, a much less complex and heterogeneous matrix than settled dust.…”

An original multiresidue method based on thermal extraction (TE) and gas chromatography/tandem mass spectrometry (GC/MS/MS) was developed to simultaneously quantify, from a very small amount of sample (a few milligrams), a wide range of concerning SVOCs, including polycyclic musks, organochlorines (OCs), organophosphates (OPs), oxadiazolones, polycyclic aromatic hydrocarbons (PAHs), polybromodiphenylethers (PBDEs), polychlorobiphenyls (PCBs), phthalates and pyrethroids, in indoor settled dust. Method limits of quantification (LOQs) ranged from 5 ng g-1 for PCBs, oxadiazon, 4,4'-DDE and 4,4'-DDT to 2000 ng g-1 for DEHP for a 2 mg sample of sieved dust. The proposed method was successfully validated in terms of accuracy and precision via replicate analysis of four different standard reference materials (SRMs 1649b (Urban Dust), 2585 (Organic Contaminants in House Dust), 2786 and 2787 (Fine Atmospheric Particulate Matter)) supplied by the National Institute of Standards and Technology (NIST) and was applied to five real indoor settled dust samples collected in French schools. In addition, its performance was compared to that of a previously published method based on pressurized liquid extraction (PLE) and GC/MS/MS. The different results obtained demonstrate the advantages of the proposed method over conventional methods and illustrate its two main features: i) its ease of use and very rapid implementation in only three steps (sieving, weighing and analysis), which make it particularly appropriate for environmental monitoring programs and large-scale studies, and ii) its ability to precisely and accurately quantify a wide range of SVOCs from trace (a few ng g-1) to highly concentrated (several mg g-1) compounds from only 2 mg of sieved dust.
