Abstract

A flow tube reactor was used to simulate the reaction of toluene and OH radical in the presence of NO_x_.The products formed in gas phase and particle phase under different relative humidity conditions (17.5%, 35%, 50%, 70%) were determined. The yields of detected products and organic carbon (OC) in the gas and particle phases were reported. The present study show that the relative humidity not only affects the ratio of the reaction pathway of toluene and×OH but also the yield and oxidation degree of the product.

Key words： relative humidity toluene gas phase product secondary organic aerosol yield
