發(fā)布時間:2022-12-11 15:03
本博士論文利用2003-2008期間在上海、北京、青島等大城市以及在榆林、多倫、烏魯木齊、塔中等沙塵源區(qū)共七處采樣點近五年的氣溶膠監(jiān)測數(shù)據(jù),采用富集系數(shù)、元素/離子特征比、后向軌跡以及包括因子分析和相關(guān)性分析在內(nèi)的多種統(tǒng)計學析方法,系統(tǒng)全面地研究了以上海為代表的中國特大城市氣溶膠的化學組成、時空分布、粒徑變化、存在形式、來源、形成機制及其與長途傳輸而來的沙塵氣溶膠的相互混合和組分轉(zhuǎn)化而產(chǎn)生的對區(qū)域大氣環(huán)境質(zhì)量的重大影響。本研究的主要成果有: 1.深刻揭示了高濃度細顆粒物、長時間灰霾和嚴重酸雨是上?諝馕廴镜娜齻典型特征。從2001年到2009年間,每年灰霾發(fā)生的天數(shù)都超過了150天。在過去的十幾年中,上海降水的pH值呈現(xiàn)出劇烈的下降趨勢,年平均酸度提高了20多倍。細顆粒物PM25的年平均濃度高達0.050-0.059mg/m3,超過國際衛(wèi)生組織年平均值標準0.015 mg/m3的3-4倍。2004年P(guān)M2.5/TSP的年平均值達到了0.41,到2007年則達到了0.53,呈逐年增長趨勢。說明了上海的細顆粒物污染程度極其嚴重。 2.詳細闡明了上海氣溶膠在不同季節(jié)的不同...
