摘要
含碳气溶胶是细颗粒物的重要组成部分之一,对气候变化和人体健康具有重要影响。识别和定量细颗粒物来源贡献是制定城市和区域空气质量改善措施的基础。天然放射性碳同位素(^(14)C)作为生物源示踪剂,可以有效地用于大气颗粒物来源分析,量化生物源和化石源相对贡献。尤其近十多年来,伴随着加速器质谱灵敏度的提高,^(14)C技术在大气颗粒物来源方面的应用越来越广泛。文中介绍了^(14)C在大气颗粒物不同含碳组分、单体分子化合物来源分析上的应用,并提出了国内研究应加强的领域和利用^(14)C技术研究大气颗粒物来源的发展趋势。
Carbonaceous particles are a major component of the fine aerosol and it plays an increasingly important role in climate and human health. The identification and quantification of the sources is necessary to improve the air quality and develop targeted control policy and measures. Radiocarbon（^（14）C） has become a unique and powerful tracer in source apportionment of atmospheric carbonaceous particles, as ^（14）C measurements enable a distinction between contemporary and fossil carbon. As Accelerator Mass Spectrometry sensitivity improves, ^（14）C technology has be widely applied in the study for source apportionment of atmospheric aerosols. This paper reviewed the development of different carbonaceous fraction for ^（14）C measurement and compiles the results from ^（14）C-based source apportionment. Then the review concluded with some comments on current issues and future prospects using ^（14）C as a tracer to determine the sources of atmospheric particles.
