| 中文摘要 |
| 对广州市不同功能区秋季大气颗粒物显微组分和优控多环芳烃(PAH)的研究表明,颗粒物显微组分主要是碳球、微粒有机质、有机质碎屑、各种矿物、生物碎屑等,不同功能区颗粒物组分的组合有所差异,它们主要来源于人为、地质和生物成因。研究区检出的美国环保局(USEPA)提出的优控PAH为15种,其浓度为27.38-228.56ng/m3,且随功能区的不同而变化。碳球、微粒有机质和有机质碎屑百分含量与优控多环芳烃浓度有很好的相关性。 |
| 英文摘要 |
| Characteristic of micro-compositions and concentrations of preceding controlled PAH(PCPAH) in atmospheric particles collected from different function zones of Guangzhou in autumn were studied in this paper.It was indicated that atmospheric individual particles are mainly composed of carbonaceous spheroids,organic micro-particulate,organic clasts,various minerals and bioclasts,which varied with function zones and came from anthropogenic,geogenic and biogenic origins.Fifteen PCPAH published by USEPA are detected in atmospheric particles and their concentrations varied with function zones are 27.38—228.56ng/m3.It was discovered that concentrations of PCPAH have well good correlation with the percentages of 3 compositions,carbonaceous spheroids,organic microparticulate and organic clasts. |
