“…For the case of phthalate esters, the highest bioaccessible fraction was reported in dust particles b63 μm while significantly lower (p b 0.05) values were reported in 280-2000 μm size fraction (Wang et al, 2013d). Finally, for of PBDEs, Yu et al (2013) reported a negative correlation (R 2 = 0.473, p = 0.028) between particle size and bioaccessibility for tri-and heptaPBDEs with the highest value of 45% for size fraction b 30 μm.…”

“…The pore volume for fractions F2 and F3 was measured the same value of 2.13 × 10 −3 cm 3 /g, then pore volume was observed to increase with decreasing particle size. In contrast, there was no inverse relation between pore volume and particle size in one study reported from Shanghai [31]. In that study, a pooled dust sample from air conditioner filters from dining halls in Shanghai University was separated into five sizes and the pore volume was comparable in all the fractions [31].…”

Background: Physical and biological properties of dust particles might affect the availability and distribution of chemicals associated to indoor dust; however it has not been adequately examined. In this study, household dust from Shanghai was fractionated into five particle sizes and size distribution, morphology, surface area, organic matter, microorganisms, elemental composition, metals and organophosphorus flame retardants (OPFRs) compositions were characterized. Also, household dust samples from Stockholm that has previously been characterized were included in the analysis of OPFRs for comparison. Results:The respirable fraction had a yield of 3.3% in mass percentage, with a particle size of 2.22 ± 2.04 µm. As expected, both metals and OPFRs concentrations increased with decreased particle size. Al and Fe dominated (66-87%) followed by the concentrations of Zn (5-14%) and Ga (1.8-5%) of the sum of 16 metals in the dust. The concentrations of OPFRs in Shanghai dust ranged from 5.34 to 13.7 µg/g (median: 7.21 µg/g), compared to household dust from Stockholm that ranged from 16.0 to 28.3 µg/g (median: 26.6 µg/g). Tris(2-chloroisopropyl) phosphate (TCIPP) and tris(2-chloroethyl) phosphate (TCEP) dominated in Shanghai dust samples while tris(2-butoxyethyl) phosphate (TBOEP) dominated in dust from Stockholm homes. Conclusion:The results showed that mass percentage for each particle size fraction was not evenly distributed. Furthermore, the particle-bound microorganisms and OPFRs increased with decreased particle size, whereas metals had the highest concentrations at specific dust sizes. Therefore, it is essential to select the proper particle size in order to assess any specific human exposure study to indoor pollutants.

“…Recent studies reported high levels of PBDEs in dust from offices, retail stores, libraries, and other workplaces (Harrad et al, 2008;Batterman et al, 2010;Watkins et al, 2013;Xu et al, 2015b). Not much is known on accumulation of PBDEs in air-conditioner filters even through central air-conditioning systems and independent air conditioners have been widely used in many indoor environments such as offices, schools, laboratories, commercial buildings, and retail stores (Ni et al, 2011;Besis et al, 2014;Xu et al, 2015b;Yu et al, 2013). To my knowledge, few studies have investigated PBDEs accumulation in air-conditioner filters in indoor workplaces (e.g., clinics and electronics factories) and thereby assessed health risks to exposed medical staff and factory employees.…”

Because consumer products release them, polybrominated diphenyl ethers (PBDEs) are frequently present in a variety of indoor environments including homes and workplaces. Our goal was to investigate PBDEs contamination of workplace air-conditioner filter dust to assess the health effects of contaminated dust on workers with occupational exposure. Nine medical clinics, four dental clinics, eight factory offices, and six factory clean rooms were selected in southern Taiwan between April 2013 and September 2014. Air-conditioner-filter dust was collected by a high-efficiency vacuum cleaner and then PBDEs were analyzed by a high-resolution gas chromatography coupled with high-resolution mass spectrometry.
