| 摘 要： | 采集广州五山、荔湾(2002-06-12～2003-06-31)2个采样点共112个PM10样品进行了GC/MS分析,结果表明2采样点全年多环芳烃浓度范围为8.11～106.26 ng·m-3,呈现出夏季低冬季高的特征.PAHs化合物的相对分布也呈明显的季节变化,5～6环PAHs的比重夏季比冬季高,而3～4环PAHs的比重冬季比夏季高.冬季PAHs可分为2种模式,不同模式之间PAHs的浓度和分布特征有明显的差异.统计结果表明,广州市多环芳烃浓度变化主要受气象条件的影响,风速(当温度＜20℃时)和温度(当温度＞20℃时)是影响多环芳烃浓度最主要的因素.此外,本研究还表明,汽车尾气排放是广州市大气颗粒物多环芳烃污染最主要的污染来源.
