Polybrominated diphenyl ethers (PBDEs) in dust samples from Czech households

Popis výsledku v původním jazyce

Polybrominated diphenyl ethers (PBDEs), a wide group of additive flame retardants (BFRs), have been intensively used in many common products to accomplish the fire safety standards. Due to their release into the surrounding environment humans´ exposure to these harmful chemicals may occur in various ways, inhalation of indoor dust with adsorbed PBDEs represents one of them. To assess the extent of contamination dust samples collected in 25 Czech households were analyzed for 16 PBDE most common congenersusing pressurized liquid extraction (PLE) for their isolation and gas chromatography coupled to negative chemical ionization mass spectrometry (GC-MS-NCI) with quadrupole analyzer for identification and quantification. The concentrations of total PBDEsranged between 81 and 3828 ng/g. Without any exception the dominating congener was no. 209. This deca-BDE contributed to the total amount of PBDEs by 73%, other relatively abundant congeners were BDE 99 (8%), BDE 206 (7%), BDE 207 (6%) an
