Short summary
The trace gas peroxypropionyl nitrate (PPN) is generated in photochemical smog, phytotoxic, a strong eye irritant, and possibly mutagenic. Here, its solubility and reactivity in water and in octanol were investigated using a bubble flow apparatus, yielding its Henry's law constant and octanol–water partition coefficient (Kow). The results allow the fate of PPN to be more accurately constrained in atmospheric chemical transport models, including its uptake on clouds, organic aerosol, and leaves.
