TL;DR: Organosulfate formation was observed only under acidic conditions for both monoterpene oxides and, to a lesser extent, campholenic aldehyde, indicating that epoxides most likely serve as precursors for some of the organosulfates reported from both ambient and laboratory SOA samples.

TL;DR: In this article, a one-year set of atmospheric PM10 filter samples that were collected at a rural background site in Hamme, Belgium was used to determine four groups of nitro-aromatic compounds (with molecular weights (MWs) of 139, 155, 169, and 183), a-pinene-related nitrooxy-organosulfates (MW 295), and the resin acid dehydroabietic acid (DHAA, MW 300) were quantified using liquid chromatography combined with negative ion electrospray ionization mass spectrometry

TL;DR: A more complete structural characterization of polar organosulfates that originate from isoprene secondary organic aerosol was achieved, and an important atmospheric finding is the presence of anorganosulfate that is related to methyl vinyl ketone, a major gas-phase oxidation product ofIsoprene.

TL;DR: In this paper, the green leaf volatiles 3-Z-hexenal serves as a precursor for biogenic secondary organic aersol through the formation of polar organosulfates (Os) with molecular weight (MW) 226.
