摘要/Abstract

摘要： 黑碳是大气气溶胶的重要组成部分，能够吸收太阳辐射产生温室效应，并对人体健康产生负面影响。选取了南京市的6个典型功能区，研究不同污染水平和不同季节下植物叶面颗粒物黑碳含量的时空分布特征，并将其与地面尘和表层土壤中的黑碳含量进行比较，探讨黑碳在多介质中的分布规律。结果表明：（1）城市植物叶面颗粒物的黑碳含量呈现冬季 > 秋季 > 春季≈夏季的季节变化特征；（2）工业区植物叶面颗粒物的黑碳含量最高，并与其他功能区的差异达显著水平；（3）城市植物叶面颗粒物黑碳含量越高，BC/OC值也越大，城市植物叶面颗粒物的黑碳主要来源于化石燃料的燃烧；（4）黑碳气溶胶通过植被表层到达地表的过程中其含量逐渐下降，植物叶面颗粒物可作为监测大气黑碳污染的有效手段。

Abstract: Black carbon has already become an important component of atmospheric pollutants which increases greenhouse effect and harms to human health. The spatial and temporal distribution characteristics of black carbon in foliar dust were studied in six different function zones in Nanjing and compared with surface dust and soils so as to investigate the distribution of black carbon in multi-medias. The results showed that the contents of black carbon in foliar dust varied greatly with seasons and rpeaked in winter. The contents of black carbon were significantly higher in industrial area than other functional zones. There was a highly significant correlation between black carbon and BC/OC, demonstrating that the accumulation of black carbon in foliar dust was strongly influenced by fossil fuels. The contents of black carbon in foliar dust were significantly higher than those in surface dust and soils of the same place, indicating that its concentration decreased gradually in the migration process from the atmosphere to the surface. Particulate matter on plant leaves can be used as an effective tool for monitoring atmospheric pollution such as black carbon.

Key words: urban plants, foliar dust, black carbon, spatial and temporal distribution
