摘要:
碳质气溶胶是大气气溶胶的重要组成部分,能够影响太阳辐射在大气层中的正常传播,与气候变化、空气污染和人类健康等关乎人类可持续发展的重要问题密切相关。大气环境中的碳质气溶胶主要包含有机碳和元素碳,其中有机碳可分为水溶性有机碳和非水溶性有机碳。碳质气溶胶的来源及其形成转化过程是目前大气环境科学领域最为重要的研究方向之一。放射性碳同位素比值(Δ14C)在碳质气溶胶源解析上具有优势,是目前唯一可以量化化石源和生物源在不同类别碳质组分中贡献大小的手段。在系统总结国内外放射性碳同位素技术在碳质气溶胶源解析上的最新研究进展的基础上,详细阐述了放射性碳同位素比值在碳质气溶胶源解析上的应用原理,深入探究了放射性碳同位素比值在碳质组分中的研究进展,重点分析了单体分子放射性碳同位素分析在碳质气溶胶中的发展和应用。最后,对放射性碳同位素比值与稳定碳同位素比值(δ13C)联用,以及单体分子标志物的放射性碳同位素比值研究进行了展望,为碳质气溶胶的来源解析和气溶胶化学过程研究提供参考依据。
Abstract:
Carbonaceous aerosols that are composed of a complex mixture of organic carbon(OC)and elemental carbon(EC),have severe impacts on the Earths climate system,air pollution and human health.OC consists of both water soluble organic carbon(WSOC)and water insoluble organic carbon(WIOC).They are directly emitted from primary anthropogenic and natural sources such as fossil fuel combustion,biomass burning and biological materials and produced by photo-oxidation reactions of gaseous organic species in the atmosphere,whereas the EC emits directly from only combustion sources. However,the apportionment of various source contributions to carbonaceous aerosols is not clear due to their complexity and lack of analytical techniques.That is why,the identification of origins and/or formation processes of carbonaceous components including EC in the given atmospheric environment has become an important research area in the field of atmospheric science.Because the measurement of radiocarbon isotope ratio(Δ14C)can distinguish the fossil and biogenic carbon content in the given samples,this technique has been considered as an unique tool in quantifying the contributions of various carbonaceous components from different sources.Based on this,the principle and application of 14C in the source apportionment of fossil and contemporary carbon in carbonaceous aerosols are introduced in detail,and the results of 14C-based source apportionment of various carbonaceous components(OC,WSOC,WIOC and EC)reported in the literature in recent times are systematically summarized. Furthermore,the compound-specific radiocarbon analysis is deeply explored,which provides better insights on the sources of organic aerosols and thus,reduces the uncertainty in their apportionment.Finally,the prospects of the combined use of Δ14C and stable carbon isotope ratio(δ13C)together with specific molecular markers are described to better identify the origins and chemical processes of organic aerosols in the atmosphere.
