摘要: 芳香化合物是二次有机气溶胶 (SOA) 的一类重要前体物, 其在大气中的氧化可以生成具有光吸收特性的棕色 碳。因此, 理解芳香化合物所生成 SOA 的光散射、光吸收、反照率等光学性质对于定量研究其对空气质量、能见度 和气候变化的影响具有重要意义。系统总结了实验室研究中单环芳香烃、含氧芳香化合物、多环芳香烃三类典型芳 香化合物所生成 SOA 的光学性质, 分析对比了文献关于光散射和光吸收参数的异同, 归纳了多种环境因素对 SOA 光 学性质的影响, 并展望了该方向未来的重点研究领域。

Abstract: Aromatic compounds are one important kind of precursors of secondary organic aerosol (SOA). The atmospheric oxidation of aromatic compounds can produce light-absorbing brown carbon (BrC). Therefore, understanding the optical properties (e.g., light scattering, light absorption, and single scattering albedo) of SOA formed from aromatic compounds has great implications on the quantification of their impact on air quality, visibility, and climate change. In this review, we summarise the optical properties of SOA formed from three typical kinds of aromatic compounds in laboratory studies: single-ring aromatic hydrocarbons, oxygenated aromatic compounds, and polycyclic aromatic hydrocarbons. The similarities and differences of light scattering and absorption parameters from literature are analyzed and compared, the impacts of various environmental factors on SOA optical properties are summarised, and the key research directions in the future are proposed.

Key words: aromatic compounds, secondary organic aerosol, brown carbon, light scattering, light absorption
