A photochemical trajectory model has been used to examine the relative propensities of a wide variety of volatile organic compounds (VOCs) emitted by human activities to form secondary organic aerosol (SOA) under one set of highly idealised conditions representing northwest Europe. This study applied a detailed speciated VOC emission inventory and the Master Chemical Mechanism version 3.1 (MCM v3.1) gas phase chemistry, coupled with an optimised representation of gas-aerosol absorptive partitioning of 365 oxygenated chemical reaction product species. In all, SOA formation was estimated from the atmospheric oxidation of 113 emitted VOCs. A number of aromatic compounds, together with some alkanes and terpenes, showed significant propensities to form SOA. When these propensities were folded into a detailed speciated emission inventory, 15 organic compounds together accounted for 97% of the SOA formation potential of UK man made VOC emissions and 30 emission source categories accounted for 87% of this potential. After road transport and the chemical industry, SOA formation was dominated by the solvents sector which accounted for 28% of the SOA formation potential.
已使用光化学轨迹模型来研究在代表西北欧的一组高度理想化条件下，人类活动排放的各种挥发性有机化合物（VOC）形成二次有机气溶胶（SOA）的相对趋势。该研究应用了详细的特定 VOC 排放清单和主化学机制版本 3.1（MCM v3.1）气相化学，并结合了 365 种含氧化学反应产物物种的气体-气溶胶吸收分配的优化表示。总之，SOA 的形成是通过对 113 种排放 VOC 的大气氧化来估算的。一些芳香族化合物，以及一些烷烃和萜烯，显示出形成 SOA 的显著趋势。当这些趋势被纳入详细的特定排放清单中时，15 种有机化合物共同占英国人为 VOC 排放的 SOA 形成潜力的 97%，30 个排放源类别占该潜力的 87%。在道路运输和化学工业之后，SOA 的形成主要由溶剂部门主导，其占 SOA 形成潜力的 28%。
