A typical petrochemical industrial area was selected as the research object, and particulate phase and gas phase samples of intermediate-volatility organic compounds (IVOCs) were collected in the air of the plant area in summer (July and August in 2021) to explore the pollution characteristics of IVOCs emission from petrochemical industrial sources and estimate their corresponding SOA (secondary organic aerosols) formation potential. The results show that, 1) the average concentration of IVOCs particle phase in typical petrochemical area is 4.22±1.54 μg/m3, and the average concentration of IVOCs gas phase is 108.87±78.93 μg/m3. The average concentration of IVOCs during the day is higher than that at night both in the gas phase and in the particle phase. 2) The n-alkanes in gas phase are concentrated from C12 to C22, while the n-alkanes in particle phase are concentrated from C22 to C35. The gas phase of polycyclic aromatic hydrocarbons is concentrated in naphthalene and phenanthrene, and the particle phase is concentrated in fluorene. 3) The IVOCs in the petrochemical industrial zone are quantitatively disassembled. The concentration is mainly concentrated in the interval B18–B21. The mass concentration sum of these four zones accounts for 60.41% of the total mass of IVOCs.

选择典型石化工业区为研究对象, 采集夏季(2021年7—8月)厂区空气IVOCs颗粒相及气相样品, 探讨石化工业源排放IVOCs的污染特征, 并估算其SOA生成潜势, 得到如下结果。1) 典型石化工业区的 IVOCs颗粒相的平均浓度为4.22±1.54 μg/m3, 气相的平均浓度为 108.87±78.93 μg/m3。不论是在气相中还是在颗粒相中, IVOCs白天的平均浓度均高于夜间。2) 气相的正构烷烃集中在C12~C22 区间, 而颗粒相的正构烷烃集中在C22~C35区间。多环芳烃气相集中在萘和菲, 颗粒相集中在芴。3) 对石化工业区的IVOCs进行定量拆解, 其浓度集中在B18~B21区间, 4个分区的质量浓度加和占总体IVOCs质量的60.41%。
