Atmospheric aerosols are important for their effects on global climate change and human health. Volatile organic compounds emitted from mobile and natural sources into the atmosphere change through photochemical reactions into lower vapor pressure compounds, these compounds condense and produce aerosol. In this study, formation of secondary organic aerosol from toluene (as anthropogenic VOC) and isoprene (as biogenic VOC) was investigated using a 2.1 m3 smog chamber. In order to elucidate the effect of relative humidity on generated aerosol growth, toluene and mixtures of it and isoprene were irradiated for 6 hours. These results for photochemical reaction suggest that the relative humidity affects on the composition and growth of secondary generated organic aerosols.
