摘　　要：为了研究石家庄市大气颗粒物TSP,PM_(10)以及PM_(2.5)中的主要成分,在不同季节分别采集了该市6个点位的颗粒物样品,对其主要成分的浓度与含量进行了分析。研究表明,TSP,PM_(10)以及PM_(2.5)中的主要成分为SO^(2-)_4,NO^-_3,NH^+_4,Al,Si,Fe,OC,EC等,这些主要成分在各粒径中呈现季节性变化的特点。春季以扬尘污染为主,冬季燃煤污染显著,夏秋季为复合型污染。市区6个点位主要成分的变化规律基本一致,"西南高教"与"西北水源"的颗粒物污染较为严重,可能与其周围污染源分布有关。In order to study the major components of atmospheric particulates TSP,PM10 and PM2.5in Shijiazhuang City,the particulate samples are collected at six points in Shijiazhuang City in every season,and the concentration and content of major components are analyzed.The Research shows that the major components of TSP,PM10 and PM2.5are SO4^2-,NO3^-,NH4^＋,Al,Si,Fe,OC/EC,and so on,and the major components varies with the season.In spring,the dust pollution is the main pollution component;in winter,the pollution of coal combustion is significant;in summer and autumn,it is composite pollution.The change rule of the major components at the six points is basically the same,while the pollution at South-west-gaojiao and North-west-headwaters is more serious,which may be related to the distribution of pollution sources.
