中国特大城市气溶胶的理化特性、来源及其形成机制
发布时间：2022-12-11 15:03
本博士论文利用2003-2008期间在上海、北京、青岛等大城市以及在榆林、多伦、乌鲁木齐、塔中等沙尘源区共七处采样点近五年的气溶胶监测数据,采用富集系数、元素／离子特征比、后向轨迹以及包括因子分析和相关性分析在内的多种统计学析方法,系统全面地研究了以上海为代表的中国特大城市气溶胶的化学组成、时空分布、粒径变化、存在形式、来源、形成机制及其与长途传输而来的沙尘气溶胶的相互混合和组分转化而产生的对区域大气环境质量的重大影响。本研究的主要成果有： 1.深刻揭示了高浓度细颗粒物、长时间灰霾和严重酸雨是上海空气污染的三个典型特征。从2001年到2009年间,每年灰霾发生的天数都超过了150天。在过去的十几年中,上海降水的pH值呈现出剧烈的下降趋势,年平均酸度提高了20多倍。细颗粒物PM25的年平均浓度高达0.050-0.059mg/m3,超过国际卫生组织年平均值标准0.015 mg/m3的3-4倍。2004年PM2.5/TSP的年平均值达到了0.41,到2007年则达到了0.53,呈逐年增长趋势。说明了上海的细颗粒物污染程度极其严重。 2.详细阐明了上海气溶胶在不同季节的不同...
