Aerosols produced from the oxidation of volatile/semi-volatile organic compounds (VOCs/SVOCs), known as secondary organic aerosol (SOA), account for a significant fraction of atmospheric airborne particles. This paper reviews the current understanding of SOA formation from gas-phase oxidation with a focus on anthropogenic precursors and their reaction products from atmospheric simulation chamber studies. The review summarises the major reaction products derived from main groups of SOA precursors (e.g., alkanes, aromatics), SOA yields and the factors controlling SOA formation. We highlight that lab-derived SOA yield depends strongly upon, not only the concentrations of SOA precursors and oxidants but also simulation conditions.

挥发性/半挥发性有机化合物 (VOCs/SVOCs) 氧化产生的气溶胶，称为二次有机气溶胶 (SOA)，占大气空气悬浮颗粒的很大一部分。本文回顾了目前对气相氧化形成 SOA 的认识，重点关注大气模拟室研究中的人为前体及其反应产物。该综述总结了源自 SOA 前体主要组（例如，烷烃、芳烃）的主要反应产物、SOA 产率和控制 SOA 形成的因素。我们强调实验室衍生的 SOA 产率不仅取决于 SOA 前体和氧化剂的浓度，还取决于模拟条件。
