Parameterization of contribution to secondary organic aerosol (SOA) formation from ambient volatile organic compounds (VOCs)
大气中挥发性有机物(VOCs)对二次有机气溶胶(SOA)生成贡献的参数化估算

Secondary organic aerosol (SOA) is a very important portion in mass concentration of ambient fine particles (PM2.5), and the volatile organic compounds (VOCs) are one of the most important precursors for SOA formation.Considering the complexity of the processes from the VOCs conversion to SOA production, the parameterization is a practical approach in estimating SOA formation potential, and hence in identifying the relative contributions of various VOC species to fine particles.Two estimation methods were introduced in this study, namely 2-products method and the volatility basis-set method, and the estimation results from recent literatures were compared.This work also discussed the existing problems in current parameterization methods.More attentions and detailed investigations should be paid in accurate quantification of VOC-to-SOA transformation in future atmospheric chemistry studies.
