Passive air sampling for semi-volatile organic chemicals

“…6F). 163 This resembles the set-up by Abdallah and Harrad, 156 but by not having a cover at the top, the lter will also be sampling larger particles subject to gravitational settling.…”

“…166,167 A wide variety of PASs have been used indoors, including SPMDs, 24,49,488,493 PE-based PASs, 490,494 SIP-PASs, 145,146,495 the original PUF-PAS 24 or modication of it with different types of housing. 156,163,164 Most recently, also a number of PASs based on PDMS have been introduced 112,114 and used. 496 While some studies compared different PASs with each other, 113 others compared PAS-derived indoor air concentrations with concentrations in other media that may serve for exposure assessment, such as surface wipes, window lms or house dust.…”

Off-Gassing of Semi-Volatile Organic Compounds from Fire-Fighters’ Uniforms in Private Vehicles—A Pilot Study

“…The analysis methods used have been previously described in-depth [10,16,17]. In summary, the extracts were analysed using a TRACE GC Ultra (Thermo Fisher Scientific, Waltham, MA, USA) coupled to a TSQ Quantum XLS (Thermo Fisher Scientific, Waltham, MA, USA) triple quadrupole mass spectrometer that was equipped with a TriPlus Autosampler.…”

Contamination Status and Emission Sources of Polychlorinated Biphenyls in Settled Dust from End-of-life Vehicle Processing and Urban Areas, Northern Vietnam

“…Trong một nghiên cứu mới được công bố gần đây, Wang và cs. (2019) đã phát hiện PCB-11 trong các mẫu bụi trong nhà và văn phòng tại Brisbane và Canberra, Australia với nồng độ trung vị 5,6 và trung bình 6,5 ± 2,5 ng/g, khá tương đồng với giá trị đo được tại Việt Nam [14].…”

“…Tỉ lệ này trong mẫu bụi trên mặt đường tại khu vực nông thôn ở Bắc Giang, khu vực đô thị ở Hà Nội, khu vực công nghiệp ở Thái Nguyên và lần lượt là 1,8; 0,2 và 0,07 [8]. Trong khi đó, tỉ lệ này ở các mẫu bụi tại Australia là 1,1 [14]. Qua đó cho thấy sự tồn tại và mức độ tương đối của PCB-11 và IN-PCBs trong mẫu bụi trong nhà tại khu vực đô thị lớn ở Việt Nam và Australia là khá tương đồng.…”
