Short summary
In this work, we found that acrolein, the smallest α,β-unsaturated aldehyde, has the potential to form light-absorbing heterocyclic secondary organic aerosol. In the gaseous phase, acrolein can react with gaseous ammonia, forming 3-picoline. In the liquid phase, the dissolved acrolein can react with ammonium to form higher molecular-weight pyridinium compounds. All the pyridinium compounds can increase the light absorptivity of aerosol particles.
