TL;DR: In this paper, a chemical mass balance receptor model based on organic compounds was developed that relates sours; contributions to airborne fine particle mass concentrations and revealed source contributions to the concentrations of specific organic compounds.

TL;DR: The major organic components of smoke particles from biomass burning are monosaccharide derivatives from the breakdown of cellulose, accompanied by generally lesser amounts of straight-chain, aliphatic and oxygenated compounds and terpenoids from vegetation waxes, resins/gums, and other biopolymers.

TL;DR: The contribution of wood smoke to the ambient concentrations of benzene, ethene, and acetylene could lead to an overestimate of the contribution of motor vehicle tailpipe exhaust to atmospheric VOC concentrations.

TL;DR: Gas- and particle-phase organic compounds present in the tailpipe emissions from an in-use fleet of gasoline-powered automobiles and light-duty trucks were quantified using a two-stage dilution source sampling system and six isoprenoids and two tricyclic terpanes have been identified as potential tracers for gasoline- powered motor vehicle emissions.

TL;DR: In this article, a two-stage dilution source sampling system was used to quantify gas and particle-phase tailpipe emissions from late-model medium duty diesel trucks using a two stage dilution sampling system.
