  • 摘要: 为研究武汉市道路尘中碳组分污染特征及来源，于2018年5月在武汉市青山区采集道路尘样品，用热光碳分析仪测定样品中有机碳（OC）、元素碳（EC）、烟炱（soot）和焦炭（char）含量，并使用特征比值法、相关分析及主成分分析法对道路尘碳组分污染特征和来源进行探讨分析.结果表明，道路尘中OC、EC、soot和char含量平均值分别为1.29、2.21、2.04、0.17 g·kg-1，说明不同碳组分含量存在较大的空间变异性.相关性分析表明OC和EC的来源存在一定差异，且EC主要贡献来源是soot.OC/EC和char/soot比值和主成分分析结果表明，武汉市青山区道路尘中碳组分主要来源于机动车尾气和燃煤排放，也可能受到生物质燃烧的影响.
    Abstract: In order to study the pollution characteristics and sources of carbon components in road dust in Wuhan City, dust samples were collected in Qingshan District, Wuhan City in May 2018. The organic carbon (OC), elemental carbon (EC), char, and soot contents of road dust samples were determined with a thermo-optical carbon analyzer. The sources of carbonaceous fraction in the dust samples were investigated by OC/EC and char/soot ratios, correlation analysis, and principal component analysis method. The results showed that the average concentrations of OC, EC, soot, and char in road dusts were 1.29, 2.21, 2.04, and 0.17 g·kg-1, respectively, indicating that there was a large spatial variability in the content of different carbon components. Correlation analysis showed that there were certain differences between the sources of OC and EC, and the main contribution source of EC was Soot. The results of OC/EC and char/soot ratios and principal component analysis showed that the pollution source of carbonaceous components of road dust in Qingshan District of Wuhan City mainly come from motor vehicle exhaust and coal combustion, and meight also be affected by emissions from biomass burning.

摘要: 为研究武汉市道路尘中碳组分污染特征及来源，于2018年5月在武汉市青山区采集道路尘样品，用热光碳分析仪测定样品中有机碳（OC）、元素碳（EC）、烟炱（soot）和焦炭（char）含量，并使用特征比值法、相关分析及主成分分析法对道路尘碳组分污染特征和来源进行探讨分析.结果表明，道路尘中OC、EC、soot和char含量平均值分别为1.29、2.21、2.04、0.17 g·kg-1，说明不同碳组分含量存在较大的空间变异性.相关性分析表明OC和EC的来源存在一定差异，且EC主要贡献来源是soot.OC/EC和char/soot比值和主成分分析结果表明，武汉市青山区道路尘中碳组分主要来源于机动车尾气和燃煤排放，也可能受到生物质燃烧的影响.
