摘    要:于2011年4月28日~5月18日对上海大气中颗粒物的质量浓度及细粒子中的化学组分进行了连续观测,获得了上海受春季沙尘天气影响下大气颗粒物质量浓度和主要化学组分特征.结果表明,沙尘天气中PM10和PM2.5的质量浓度显著高于非沙尘天,最高日均浓度分别达到787.2μg·m-3和139.5μg·m-3,PM2.5/PM10的均值为(32.9±14.6)%(15.6%~85.1%);总水溶性无机离子(TWSⅡ)占PM2.5的质量分数为(27.2±19.2)%(4.8%~80.8%),二次组分SNA(SO2-4、NO-3、NH+4)占TWSⅡ的(76.9±13.9)%(41.9%~94.2%),TWSⅡ和SNA对PM2.5的贡献均小于非沙尘天,而Ca2+的含量比却有明显上升.非沙尘天测得的OC/EC值高于强沙尘天,但低于弱沙尘天.此外分析还得到,沙尘中的高矿尘粒子具有酸性缓冲作用,使得沙尘天颗粒的碱性强于沙尘发生前.非沙尘天SO2-4、NO-3主要以NH4HSO4、(NH4)2SO4和NH4NO3的形式存在,沙尘天还会与其他矿物离子结合.

关 键 词:沙尘  颗粒物  化学组分  水溶性离子  离子形态
