摘要: Atmospheric PCDD/Fs and dl-PCBs samples were collected in Hochiminh city, Vietnam to address the effect of meteorological parameters, especially rainfall, on occurrence gas/particle partitioning these persistent organic pollutants. The results indicate that concentrations industrial site are higher than those measured commercial rural sites during both rainy dry seasons. In terms mass concentration, ambient PCDD/F levels season significantly while dl-PCB do not vary between difference could be attributed different characteristics dl-PCBs. found mainly distributed particle phase dl- PCBs predominantly gas Additionally, Junge-Pankow Harner-Bidleman models applied better understand pollutants atmosphere. As a results, under non-equilibrium condition, tend reach equilibrium easier there no clear trend for model performs evaluating prediction
