摘要
大气颗粒物吸湿性是反映颗粒物理化性质的重要指标,吸湿性研究对深入了解颗粒物的环境和健康效应具有重要意义.总结了国外近年来大气颗粒物吸湿性研究进展:①典型的大气颗粒物吸湿性分析方法为H-TDMA(吸湿性串联差分电迁移率粒径分析仪)系统及其优化方法.②大气颗粒物吸湿性呈单峰、双峰甚至多峰分布;根据Gf(吸湿性生长因子)随粒径变化的模式,可将大气颗粒物分为强吸湿性和弱吸湿性2类,也可分为纯不溶性、混合不溶性、混合可溶性和纯可溶性4类.③城市背景点颗粒物的Gf比城市观测点高;城市观测点的颗粒物Gf分布呈夏季高、冬季低,白天高、晚上低的特征.④颗粒物吸湿性与其化学组成和形态密切相关,纯可溶性盐颗粒物的Gf通常较高.⑤柴油燃烧源新排放的颗粒物属于弱吸湿性颗粒物,Gf非常小,但在其表面老化后或随燃料中硫含量的增加Gf会明显变大.⑥生物质燃烧排放颗粒物的Gf相对较高,但存在区域差异性.针对国内大气颗粒物吸湿性研究现状,提出了未来重点研究方向.
