Air particle samples collected from a typical workshop of Southern China engaged in recycling waste printed circuit boards were analyzed for PBDEs, PCDD/Fs, and PBDD/Fs. The concentrations and profiles of these compounds were presented. Concentrations of Sigma PBDEs, Sigma PCDD/Fs and Sigma PBDD/Fs in this workshop were 948 ng m(-3), 317 pg m(-3) (14.5 pg WHO-TEQ m(-3)) and 481 pg m(-3) (91.3 pg I-TEQ m(-3)), respectively. BDE5-47, -99, and -209 were the dominant PBDE congeners, and the relatively high levels of octa- and nona-BDEs might be generated from the degradation of BDE-209. The levels of 2,3,7,8-PCDD/Fs and 2,3,7,8-PBDD/Fs were much higher than those in the atmospheric environment, and concentrations of PBDD/Fs were higher than those of PCDD/Fs. These findings suggest that the primitive recycling method represents a strong source of halogenated organic pollutants to the ambient atmosphere of an e-waste recycling locale.
