Abstract
Biogenic volatile organic compounds (BVOCs) which offer high reactivity are important precursors for the formation of ozone (O3) and secondary organic aerosols (SOA), then leading to air pollution. In order to explore the potential correlation between BVOCs and O3 and SOA, and to screen out better tree species for urban greening, in this paper, 32 tree species were selected to carry out related experiments. The results showed that: hydrocarbons, alcohols, and aldehydes were significantly correlated with SOA generation, and ketone, ester, hydrocarbons and alcohols also showed significant relationship with O3. Analyzed by UPGMA cluster, Ailanthus altissima, Acer truncatum, Rhus typhina, Prunus cerasifera f. atropurpurea, Prunus persica f. Duplex and Cerasus serrulata var. lannesiana were found weak correlation with O3 and SOA generation, while Salix matsudana, Populus tomentosa and Salix matsudana f pendula were strongly related.
