The aim was to acquire information about the concentrations, gas/particle partitioning and distribution of polybrominated diphenyt ethers (PBDEs). 11 congeners PBDEs were detected with GC-NCI-MS. The results showed that E-waste dismantling has resulted in serious pollution and the PBDE concentrations (from tri-to deca-BDE) ranged from 51.1 pg·m-3 to 2685 pg·m-3 (mean:830 pg·m-3), while the PBDE concentrations (from tri-to deca-BDE) in S were in the range of 1.00 pg·m-3 to 98.9 pg·m-3 (mean: 28.7 pg·m-3). The gas/particle partitioning of PBDEs exhibited a strong dependence on bromine number. Low-brominated PBDEs tend to have a higher concentration in the gas-phase while highly brominated PBDEs are mostly associated with the particulate. The mass distribution of PBDEs in E (including vapor-phase and particulate-phase) was dominated by penta-BDE, accounting for 54.3% of the total PBDEs, followed by deca-BDE, accounting for 23.8%. This pollution characters validated that the E-waste did not only come from Asia, but also from North America and Europe. ER -
