氯代和溴代多环芳烃（Cl/Br-PAHs）是雾霾相关颗粒物（PM）中的一类新的半挥发性有机污染物。它们在PM组分中的气相颗粒相分配和分布还不清楚。澄清将增加对氯/溴多环芳烃的大气行为和健康风险的理解。在这项研究中，气相和4个PM相（空气动力学直径（d（ae））> 10 μ m，2.5-10 μ m，1.0-2.5 μ m，
Chlorinated and brominated polycyclic aromatic hydrocarbons (Cl/Br-PAHs) are emerging semi-volatile organic pollutants in haze-associated particulate matter (PM). Their gas particle phase partitioning and distribution among PM fractions have not been clarified. Clarification would increase understanding of atmospheric behavior and health risks of Cl/Br-PAHs. In this study, samples of the gas phase and 4 PM phases (aerodynamic diameters (d(ae)) > 10 mu m, 2.5-10 mu m, 1.0-2.5 mu m, and
