Özet

Factors influencing the diurnal atmospheric concentrations and soil-air exchange of polybrominated diphenyl ethers (PBDEs) were investigated at an e-waste recycling site in China during winter and summer. Total PBDE concentrations in winter and summer were 11.0e42.4 and 120e431 pg/m3 in the gaseous phase and 13.3e234 and 69.0e208 pg/m3 in the particulate phase, respectively. Total PBDE concentrations in the e-waste contaminated and nearby soils were 869 and 611 ng/g in winter and 2130 and 31 ng/g in summer, respectively. Concentrations in the gaseous phase were significantly higher in summer than in winter, but concentrations in the particle phase were comparable between winter and summer. Because of the influence of occasional accidental inputs, no apparent diurnal variations were found for PBDEs in either the particle or gaseous phase. Both temperatures and local emissions affected air concentrations of PBDEs in this area. The estimated directions of soil-air exchange of PBDEs suggest that the e-waste contaminated soil generally acted as a secondary source of several low brominated PBDEs, while the nearby soil acted as a secondary source of BDE28. The diurnal variation of atmospheric concentrations of PBDEs is not strong enough to alter the soil-air exchange direction.
