Indoor deposition flux and congener profiles of polybrominated diphenyl ethers (PBDEs) in Shanghai, China

Indoor dry deposition of eight homes and offices in the urban area of Shanghai, China were sampled with clean glass plate during July to August of 2008 to study the indoor deposition flux and congener profiles of polybrominated diphenyl ethers (PBDEs). 16 PBDEs congeners which including BDE-17, -28,...

Summary:Indoor dry deposition of eight homes and offices in the urban area of Shanghai, China were sampled with clean glass plate during July to August of 2008 to study the indoor deposition flux and congener profiles of polybrominated diphenyl ethers (PBDEs). 16 PBDEs congeners which including BDE-17, -28, -71, 47, -66, -77, -100, -99, -85, -118, -154, -153, -138, -183, -190 and BDE-209 were measured by GC-MS with negative chemical ionization (NCI) in selected ion monitoring (SIM) mode. The particulate deposition flux of PBDEs in homes and offices were (10.9 +/- 8.2) and (14.2 +/- 11.9) ng x (m2 x d)(-1) respectively. Deca-BDE (BDE-209) was the major compound, accounting for 88.2% -99.2% of the quantified PBDEs. The particulate deposition flux in the offices [(3.1 +/- 2.0) mg x (m2 x d)(-1)] was relatively lower than that of homes, but the concentration of PBDEs in the particles [(3361.6 +/- 1987.4) ng x g(-1)] was significantly higher than that of homes [(1169.1 +/- 647.1) ng x g(-1)]. The concentration of PBDEs in
