Preliminary results on polybrominated diphenyl ether contamination status in Croatian households and insights into children's exposure

PBDEs Found in House Dust Impact Human Lung Epithelial Cell Homeostasis

“…Commercial standards of BDE-28 (2,4,4 - Each PBDE congener was reconstituted in methanol (J. T. Baker, Derventer, The Netherlands) at a concentration of 500 µg mL −1 and diluted further for experimental purposes. An extract of real house dust in n-hexane containing a total PBDE concentration of 17 µg mL −1 [19] was also reconstituted in methanol to obtain a final concentration of 340 µg mL −1 and was diluted further, according to the needs of the experiment.…”

“…Assessments of the effects of PBDEs on the human respiratory system are scarce and limited to only three congeners: BDE-47, -99 and -209 [9,14,17,18]. However, a recently analyzed house dust sample from Zagreb, Croatia, pointed to the presence of several other congeners contributing to higher overall PBDE concentrations [19]. In the most contaminated dust sample, the sum of seven PBDE congeners exceeded 17 µg g −1 dust.…”

Polybrominated diphenyl ethers and polycyclic aromatic hydrocarbons in dust from different indoor environments in Zagreb, Croatia: Levels and human exposure assessment

“…Calculations of EDI values (ng kg −1 bw day −1 ) were performed as in our previous paper 12 using the same equations: where γ dust is the mass fraction of the targeted PBDE congener or ΣPBDE measured in dust samples (ng g −1 dust), while HEF represents the indoor exposure fraction, that is, the fraction of the day spent in each microenvironment. All the remaining parameters used in these equations are explained in Supplementary data (Table S3).…”

“…For some areas, including Croatia, data are very scarce. To date, the data reported by our research group [11][12][13] refer to PBDEs in dust from homes, while there are no data for other indoor locations. Additionally, PAHs have mainly been investigated in outdoor environments (air, soil, road dust), and much less in indoor dust, and for Croatia, there are no data on PAHs in indoor dust of any kind.…”
