文摘

Atmospheric PCBs and PBDEs were measured at the Chinese Great Wall Station, West Antarctica during 2011–2014. Nonracemic residues were commonly observed for chiral PCBs. Significant temperature dependence was observed for lighter PCBs (excluding PCB-11) in 2011 and 2012. The gas/particle partitioning behavior was evaluated by the steady-state-based model and equilibrium-state-based model.
