Secondary organic aerosol (SOA) produced by ozonolysis of styrene and other alkene compounds is a major part of fine particles in urban atmospheres. The atmospheric ozonolysis process of styrene is simulated in a smog chamber, and the formed SOA particles are detected on-line by a synchronous radiation vacuum ultraviolet photoionization mass spectrometer (VUV-PIMS) in this study. Through molecular ion peaks in the photonionization mass spectra of SOA and the corresponding photoionization efficiency curve, combined with off-line measurement verification of ultraviolet visible and infrared absorption spectra, it is determined that formaldehyde, formic acid, benzene, phenol, benzaldehyde, and benzoic acid are the main constituents of styrene SOA. These provide new information for studying the atmospheric ozonolysis oxidation mechanism of styrene. VUV-PIMS can get over complicated sample preparation procedures, secondary pollution, and other shortcomings of the off-line method and is a useful instrument to measure constituents and unveil the formation process of SOA particles.

“…Styrene+OH also forms benzoic acid (C 7 H 6 O 2 ) and C 8 H 8 O 2 . 22 Only three identifiable products were found in the EESI+ data for the furfural + OH reaction. Two products, C 5 H 4 O 3 and C 5 H 4 O 4 , were identified based on the mechanism in Zhao and Wang.…”

“…Styrene Y SOA is compared in Figure 4g with literature reports for both high and low NO x . Yu et al 22 reported higher Y SOA under low NO x (0.25 at [OA] ∼ 400 μg m −3 ) vs high NO x conditions (0.01 at [OA] ∼ 15 μg m −3 ). However, the low NO x case is not directly comparable to our study, while the high NO x case is at the lower limit of our OA range.…”

“…SOA yields for the phenolic species and styrene have been measured in atmospheric chambers. − To our knowledge, only one study has reported an SOA yield for furfural, and no studies have reported a measured SOA yield for methyl furfural. None of the studies cover the commonly observed high OA concentrations in BB plumes (>100 μg m –3 ).…”

“…SOA yields depend strongly on the total OA available for gas ↔ particle partitioning, 22,24−27 so quantifying the [OA] dependence of Y SOA is essential for modeling SOA under real-world conditions. In particular, as BB smoke ages and dilutes, the concentration of OA decreases from ∼2000 to 10 μg m −3 and less.…”

Wildfires are increasing in frequency and intensity, with increasing impacts on air quality and climate. A main component of smoke is biomass-burning organic aerosol, BBOA, including both primary OA (POA) and secondary OA (SOA). Here, we provide wildfire-relevant SOA yields for the reactions of 5 BB volatile organic compounds (VOCs) that have been predicted to lead to substantial SOA formation (phenol, catechol, styrene, furfural, and methyl furfural). Reactions were conducted in a large Teflon chamber with OH under high-NO conditions. We focus specifically on providing SOA yields and volatility basis sets (VBSs) that can be applied to ambient data, including at high OA concentrations in large plumes. We introduce a new method for obtaining VBSs while accounting for Teflon environmental chamber wall effects and for changes in temperature during experiments. Vapor wall loss corrections increase SOA by ∼30% across different systems. The SOA from this work is estimated to evaporate faster upon dilution than POA. We also analyze mass spectra from particle-phase measurements, which confirm the presence of SOA species identified by other researchers, and report nitrocatechol mass yields for phenol (38%) and styrene (0.45%).
