Short summary
Particulate active metallic oxides in dust were proposed to influence the photochemical reactions of ambient volatile organic compounds (VOCs). A case study investigated the origin and transformation of VOCs during a windblown dust-to-haze pollution episode. In the dust event, a sharp decrease in VOC loading and aging of their components was observed. An increase in Ti and Fe and a fast decrease in trans-/cis-2-butene ratios demonstrated that dust can accelerate the oxidation of ambient VOCs.
