Abstract:

Preliminary experiments were performed in an environmental smog chamber to study the influence of relative humidity and the presence of certain aerosols on the formation of photochemical aerosols and cloud condensation nuclei. The specific gaseous reactants chosen for this study were SO2 and the combination of propylene and NO2. The photooxidation of some key pollutants and the accompanying aerosol formation was observed under different humidity regimes. The subsequent interaction of the moisture with the photochemical aerosol under fog forming conditions was investigated.
