dc.description.abstract多环芳烃(PolycyclicAromaticHydrocarbons,简称PAHs)是一类半挥发性有毒有机物,一旦排放进入大气,就会在气相和颗粒相之间进行分配,其中高分子量PAHs主要以颗粒相形式存在,低分子量PAHs则主要以气相形式存在。吸附于气溶胶上的PAHs在大气迁移过程中,可由干湿沉降和光降解从大气中清除,其中PAHs的光降解速率受PAHs本身的性质及颗粒基质组成所影响。气溶胶颗粒中存在的光敏剂如4-甲基邻苯二酚、愈创木酚(又称2-甲氧基酚)、紫丁香醇(又称2,6-二甲氧基苯酚)可在一定程度上改变PAHs的光解速率,进而影响PAHs的大气停留时间和迁移距离。 本研究以蒽(Anthr...
dc.description.abstractPolycyclic aromatic hydrocarbons (PAHs) are identified to be one of the major toxic air pollutants in urban. When PAHs enter into aerosol, it will be distributed between gas phase and particles phase. PAHs mainly exist in the particle phase with high molecular weight, while exist in the gas phase with low molecular weight. When PAHs are absorbed in aerosol, they will be cleared from the atmosphere...
