title: Halogenated organic pollutants in particulate matters emitted during recycling of waste printed circuit boards in a typical e-waste workshop of Southern China.
abstract: 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 ofPPBDEs,PPCDD/Fs andPPBDD/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. BDEs-47, -99, and -209 were the dominant PBDE congeners, and the relatively high levels of octaand 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.
