摘要：

The hydroxylated PBDEs (OH-PBDEs) and brominated phenolic compounds in aerosol samples from a printed circuit boards recycling workshop were characterized. The results show that OH-PBDEs, which are naturally occurring compounds or metabolism of PBDEs, could also be emitted from the e-waste recycling. Five OH-PBDEs, several unidentified mono-OH-PBDE and di-OH-PBDE congeners were detected. The concentration of Sigma OH-PBDEs was 1.74-4.22 ng m(-3) (average of 2.66 ng m(-3)), with 6-OH-BDE-47 (0.329 ng m(-3)) as the most abundant identified congener. The total concentration of di- to tri-brominated phenols (BPs) was 18.8-32.0 ng m(-3) (average of 26.3 ng m(-3)) with 2,4,6-triBP as the most abundant congener. These findings suggest that the recycling of printed circuit boards represent a strong source of OH-PBDEs and BPs to the atmosphere. Additionally, some phenolic compounds including brominated bisphenol A, hydroxylated polybrominated biphenyl species and etc. were also identified. (c) 2013 Elsevier Ltd. All rights reserved.
