2、濃度及化學(xué)成分含量的測(cè)定;同時(shí)根據(jù)污染源調(diào)查的結(jié)果結(jié)合顆粒物化學(xué)組成特征分析,確定了土壤風(fēng)沙塵,燃煤塵,建筑塵,道路揚(yáng)塵,汽車尾氣塵,燃油塵,硫酸鹽和硝酸鹽等十幾種源類進(jìn)行研究,科學(xué)地采集了源樣品并進(jìn)行成分分析,同步建立了東莞市大氣顆粒物的源和受體成分譜的數(shù)據(jù)。在此基礎(chǔ)上建立了東莞市源解析的化學(xué)質(zhì)量平衡(c舳)受體模型。并利用CMB8.0模型進(jìn)行計(jì)算,得到各源類對(duì)大氣顆粒物PM。。濃度的貢獻(xiàn)率:土壤風(fēng)沙塵17.6%、燃煤煙塵23.6%、汽車尾氣塵13.9%、硫酸鹽9.4%、餐飲油煙15.5%、建筑水泥塵13.49%、硝酸鹽3.1%、海鹽3.3%:同時(shí)還運(yùn)用富集因子法和因子
3、分析法兩種數(shù)學(xué)分析方法對(duì)PM.。的主要來源進(jìn)行了初步的探討和分析,共鑒別出5種主要來源,并估算出這5種源的貢獻(xiàn)率分別為:土壤風(fēng)沙塵與垃圾焚燒煙塵22.5%,建筑水泥塵和燃煤塵25.5%,機(jī)動(dòng)車尾氣塵13.5%,餐飲油煙19.096,金屬加工類13.3%,其他源類6.2%。兩種結(jié)果表明,C腿和FA是比較可靠的源解析研究方法,解析的結(jié)果與東莞市的實(shí)際情況基本吻合.關(guān)鍵詞:大氣顆粒物;源解析;化學(xué)質(zhì)量平衡:因子分析;富集因子;污染控制對(duì)策Ⅱ東北大學(xué)碩士學(xué)位論文AbstractStudyonsourcesapportionment&controlcountermeasuresof
