N2 - Secondary organic tracer compounds for secondary organic aerosol (SOA) formed from isoprene, monoterpenes, β-caryophyllene, and toluene were identified and quantified in 51 samples collected at four sites in Hong Kong during the summer of 2006. The measured ambient concentrations of these tracer species, together with their laboratory-derived SOA mass fractions, were used to assess the SOC and SOA contributions of their respective VOC precursors. Monoterpenes and β-caryophyllene were significant SOA contributors in Hong Kong during the summer. This was consistent with the high annual monoterpene emissions observed in Hong Kong and also indicated an abundant β-caryophyllene emission in this area. Higher SOA concentrations and contributions to OC were observed on the days mainly influenced by regional sources due to elevated oxidant levels than those affected mainly by local sources. This is an abstract of a paper presented at the 101st AWMA Annual Conference and Exhibition (Portland, OR 6/24-27/2008).
