| 摘 要： | 研究了北京市2000年采暖期和非采暖期2个典型代表月(6月和12月)不同粒径颗粒物的质量浓度特征以及不同粒径颗粒物中ρ(PAHs)分布特征,并同时利用比值法和化学质量平衡(CMB)受体模型对可吸入颗粒物(PM10)中PAHs的来源进行识别和解析.研究结果表明:北京市采暖期ρ(颗粒物)明显高于非采暖期;采暖期和非采暖期不同粒径颗粒物的比例有差别,采暖期、非采暖期ρ(PM10)分别约占ρ(TSP)的0.662和0.734;PAHs具有更明显富集于细颗粒物中的特征;源解析结果表明燃煤污染和机动车污染是PM10中PAHs的最主要来源.

| Abstract: | Mass concentrations characteristics of airborne particulates of different sizes and mass concentration distribution of PAHs in airborne particulates of different sizes in Beijing in two typical months, June and December 2000, representing non-heating and heating seasons, were investigated. Source identification and apportiontment of PAHs was processed by both ratio method and CMB receptor model for the inhalable particulates (PM_(10((. The results show that mass concentration of particulates in Beijing was much higher in heating season than that in non-heating season. The mass proportions of particulates of various sizes between different seasons were different. The proportion of PM_(10( in total particulate matters was 0.662 in heating season and 0.734 in non-heating season. PAHs were much enriched in fine particulates. Results of source apportiontment show that coal burning and vehicle emissions are the major sources of PAHs in PM_(10(. |
