Abstract
Numerous laboratory experiments have been performed in an attempt to mimic
atmospheric secondary organic aerosol (SOA) formation. However, it is still
unclear how close the aerosol particles generated in laboratory experiments
resemble atmospheric SOA with respect to their detailed chemical
composition. In this study, we generated SOA in a simulation chamber from
the ozonolysis of α-pinene and a biogenic volatile organic compound
(BVOC) mixture containing α- and β-pinene, Δ3-carene, and isoprene. The detailed molecular composition of
laboratory-generated SOA was compared with that of background ambient
aerosol collected at a boreal forest site (Hyytiälä, Finland) and an
urban location (Cork, Ireland) using direct infusion nanoelectrospray
ultrahigh-resolution mass spectrometry. Kendrick mass defect and van
Krevelen approaches were used to identify and compare compound classes and
distributions of the detected species. The laboratory-generated SOA
contained a distinguishable group of dimers that was not observed in the
ambient samples. The presence of dimers was found to be less pronounced in
the SOA from the BVOC mixtures when compared to the one component precursor
system. The molecular composition of SOA from both the BVOC mixture and
α-pinene represented the overall composition of the ambient sample
from the boreal forest site reasonably well, with 72.3 ± 2.5%
(n = 3) and 69.1 ± 3.0% (n = 3) common ions, respectively. In
contrast, large differences were found between the laboratory-generated BVOC
samples and the ambient urban sample. To our knowledge this is the first
direct comparison of molecular composition of laboratory-generated SOA from
BVOC mixtures and ambient samples.
