英文摘要: Cis-3-hexen-1-ol (cis-HXO) is a green leaf volatile emitted from plants under stress and belongs to an important class of biogenic volatile organic compounds. In this study, we have investigated the potential formation of organosulfates (OSs) from the hydroxyl radical (OH)-initiated oxidation and ozonolysis of cis-HXO using either non-acidified or acidified sulfate seed aerosols under different relative humidity (RH) conditions. For selected ozonolysis experiments, an OH scavenger was utilized. Ultra performance liquid chromatography interfaced to high-resolution quadrupole time-of-flight mass spectrometry with electrospray ionization (UPLC/ESI-HR-Q-TOFMS) was used to characterize cis-HXO-derived secondary organic aerosol (SOA) formation. Chemical characterization of cis-HXO-derived SOA products reveals that OSs were generated in significant quantity from multiphase chemistry of gas-phase oxidation products of cis-HXO. Ambient fine aerosol (PM2.5) samples collected from Rio de Janeiro, Brazil, were also analyzed. Seven cis-HXO-derived OSs identified in the lab study with molecular weights 154, 186, 170, 210, 212, 226 and 270 were also found in the PM2.5 samples collected in Brazil. This study provides direct evidence that the oxidation of cis-HXO by OH and O3 yields biogenic SOA through the formation of polar OSs. © 2017 Elsevier Ltd Citation statistics:
