  • 摘要: 为探讨石家庄市冬季道路积尘中PM2.5与PM10的碳组分污染特征和来源，利用移动式采样法对市区不同类型铺装道路积尘进行收集，用热光碳分析仪测定样品中有机碳（OC）和元素碳（EC）的含量并分析其特征.结果表明，OC、EC在PM2.5中的平均质量浓度为166.54 mg·g-1、25.35 mg·g-1，在PM10中的平均质量浓度为118.31 mg·g-1、20.3 mg·g-1，总碳（TC）占PM2.5中百分比为19.2%，占PM10 13.9%，表明碳组分更容易富集到细粒径颗粒物上；相关性分析表明OC、EC来源大致相同；8个碳组分中OC3的百分含量最高，OC4次之，EC3最低；主成分分析及OC、EC相关分析结果表明冬季道路积尘中的碳主要来自于机动车尾气排放和大气降尘中的燃煤成分.
    Abstract: To reveal the characteristics and sources of carbonaceous components in PM2.5 and PM10 of paved road dust in Shijiazhuang during winter, dust samples were collected from 4 different types of roads in Jan.2015, and were dried, sieved, weighed, particle size analyzed, and re-suspended. Then organic carbon (OC) and elemental carbon (EC) were analyzed by using thermal/optical carbon analyzer. Results showed that the average mass concentrations of OC and EC in PM2.5 were 166.54 mg·g-1 and 25.35 mg·g-1, while those in PM10 were 118.31 mg·g-1 and 20.3 mg·g-1. Percentage of total carbon(TC) in PM2.5 was 19.2%, while 13.9% in PM10. It indicated that carbon component enrich easihy in fine particulate matter. Correlation analysis showed that the sources of OC and EC were approximately similar. The percentage of OC3 is the highest among 8 carbon components, then OC4, while EC3 has the lowest percentage. Through the principle component analysis, it was found that the carbon components pollution mainly come from vehicle exhaust and deposition of airborne dust with coal combustion.

摘要: 为探讨石家庄市冬季道路积尘中PM2.5与PM10的碳组分污染特征和来源，利用移动式采样法对市区不同类型铺装道路积尘进行收集，用热光碳分析仪测定样品中有机碳（OC）和元素碳（EC）的含量并分析其特征.结果表明，OC、EC在PM2.5中的平均质量浓度为166.54 mg·g-1、25.35 mg·g-1，在PM10中的平均质量浓度为118.31 mg·g-1、20.3 mg·g-1，总碳（TC）占PM2.5中百分比为19.2%，占PM10 13.9%，表明碳组分更容易富集到细粒径颗粒物上；相关性分析表明OC、EC来源大致相同；8个碳组分中OC3的百分含量最高，OC4次之，EC3最低；主成分分析及OC、EC相关分析结果表明冬季道路积尘中的碳主要来自于机动车尾气排放和大气降尘中的燃煤成分.
