Nitrogen-containing secondary organic aerosol formation by acrolein reaction with ammonia/ammonium

Secondary organic aerosol formation

Introduction Conclusions References

Nitrogen-containing organic compounds and oligomers in secondary organic aerosol formed by photooxidation of isoprene.

Electrospray ionization high-resolution mass spectrometry (ESI HR-MS) was used to probe molecular structures of oligomers in secondary organic aerosol (SOA) generated in laboratory experiments on isoprene photooxidation at low- and high-NO(x) conditions. Approximately 80-90% of the observed products are oligomers and up to 33% by number are nitrogen-containing organic compounds (NOC). We observ...

Secondary organic aerosol formation from isoprene photooxidation.

Recent work has shown that the atmospheric oxidation of isoprene (2-methyl-1,3-butadiene, C5H8) leads to the formation of secondary organic aerosol (SOA). In this study, the mechanism of SOA formation by isoprene photooxidation is comprehensively investigated, by measurements of SOA yields over a range of experimental conditions, namely isoprene and NOx concentrations. Hydrogen peroxide is used...
