“…Median concentrations of DBDPE reported here for Irish homes exceed those reported for Swedish homes 52 Australian homes (also sampled in 2016) 48 and homes in Beijing 53 . Median DBDPE concentrations reported for Irish cars also exceed those in Greece 54 , while those in Irish offices exceed those in Australia 48 .…”

Concentrations of decabromodiphenyl ethane (DBDPE), 13 polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCDD), were measured in indoor air and dust collected from Irish homes, cars, offices and primary schools during 2016-17. Median concentrations of DBDPE in air (88 pg/m 3) and dust (6,500 ng/g) exceed significantly those previously reported internationally, with concentrations highest in offices and schools, suggesting DBDPE is widely used in Ireland. Median concentrations of BDE-209 in air (340 AUTHOR INFORMATION

“…Many FRs are frequently added in those parts because of the risk of overheating due to the accumulated dust between the plug and the wall outlet [41]. About the other 12 nBFRs, BTBPE average values were higher than other studies [32,33,38,42] and HBB showed average values about ten times higher than the literature values [33,36,38,42]. TBP and TBPH were detected in all samples, in agreement with other studies (100% of samples incidence) [32,43].…”

“…Similar to PCBs, ΣBDEs was higher in electronic and mechanical workshops (D4 and D5). BDE 209 is the most widespread BDE and it was found in high concentrations in several studies [36][37][38]. In our work, BDE 209 was detected only in one sample (D5) and it represented the most concentrated (2368.0 ng/g) compound among BDEs investigated.…”

“…In this study, TBBPA was not detected in the other samples, possibly because of the high LOD of our method (124.1 ng/g). D4 concentration was two orders of magnitude higher compared to TBBPA concentrations in other indoor dust studies [9,36,39]. However, high TBBPA concentrations were found in workplaces where similar activities were carried out, such as dismantling of electronic devices in recycling plants [40].…”

The occurrence of halogenated organic pollutants in indoor dust can be high due to the presence of textile, electronic devices, furniture, and building materials treated with these chemicals. In this explorative study, we focused on emerging organic pollutants, such as novel brominated flame retardants (nBFRs) and some perfluoroalkyl substances, together with legacy polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (BDEs) in settled dust collected in houses and workplaces such as one office and two electrotechnical and mechanical workshops. The total contribution of the investigated pollutants was lower in house and in office dusts except for few nBFRs (such as bis (2-ethylhexyl)-3,4,5,6-tetrabromo-phthalate at a concentration of 464.5 ng/g in a house and hexachlorocyclopentadienyldibromocyclooctane at 40.4 ng/g in the office), whereas in electrotechnical and mechanical workshops a high incidence of PCBs, BDEs, and nBFRs occurred (for example, BDE 209 at a concentration of 2368.0 ng/g and tetrabromobisphenol A at 32,320.1 ng/g in electrotechnical and mechanical workshops). Estimated daily intakes were also calculated, showing that domestic and occupational environments can lead to a similar contribution in terms of human exposure. The higher exposure contribution was associated to nBFRs, whose EDIs were in the range of 3968.2–555,694.2 pg/kg bw/day. To provide a complete view about the indoor contamination, in this investigation, we also included polycyclic aromatic hydrocarbons (PAHs) and their oxygenated and nitrated derivatives. Definitely, dust collection represents a simple, fast, and cost-effective sampling and dust contamination level can be a useful indicator of environment healthiness. Besides, the presented method can be a smart tool to provide a time and money saving technique to characterize 99 pollutants thanks to a single sample treatment.

“…It is noteworthy that the Σ PBDE value in D5, strongly affected by the PBDE 209, was detected in the highest concentration among the PBDEs. PBDE 209 is the most widespread PBDE, found in high concentration in several studies [14][15][16].…”

In indoor environments, the concentration of halogenated organic pollutants in dust can be high due to the presence of products treated with these chemicals. In this study, we monitored emerging organic pollutants, such as novel brominated flame retardants (nBFRs) and some perfluoroalkyl substances (PFAS), together with legacy polychlorinated biphenyls (PCB) and polybrominated diphenyl ethers (PBDEs) in settled dust collected in five different (domestic and occupational) environments. In workplaces, a high incidence of PCBs, PBDEs and nBFRs occurred. Dust collection represents a simple, fast and cost-effective sampling and dust contamination level can be a useful indicator of environment healthiness.
