| Abstract: | Diurnal air samples were collected from the E-waste dismantling region Guiyu and the underwear industry region Chendian. This was the first report to present the diurnal variation of PBDEs in the atmosphere. The average concentrations of 11 PBDE congeners were 11,742 pg m−3 in the daytime, and 4830 pg m−3 at night in Guiyu, while the concentrations were lower in Chendian with 376 pg m−3 in the daytime, and 237 pg m−3 at night. BDE-209 accounted for 22% and 31.3% of the total PBDEs in Guiyu and Chendian, respectively. The diurnal variation trends of BDE-47, -99, -153, -183, and -209 were also analyzed in detail in the two regions. |
