Summary

We investigated total suspended particles (TSP) collected from central Alaska, USA for molecular compositions of secondary organic aerosol (SOA) derived from the oxidation of biogenic volatile organic compounds (BVOCs). Isoprene-, α-/β-pinene- and β-caryophyllene-SOA tracers were determined using gas chromatography-mass spectrometry. The concentration ranges of isoprene, α-/β-pinene and β-caryophyllene oxidation products were 0.02–18.6 ng m−3 (ave. 4.14 ng m−3), 0.42–8.24 ng m−3 (2.01 ng m−3) and 0.10–9 ng m−3 (1.53 ng m−3), respectively. Isoprene-SOA tracers showed higher concentrations in summer (ave. 8.77 ng m−3), whereas α-/β-pinene- and β-caryophyllene-SOA tracers exhibited highest levels in spring (3.55 ng m−3) and winter (4.04 [...]
