The Henry's Law solubility and first order loss rates of PAN (peroxyacetic nitric anhydride, CH3C(O)OONO2) in a model non-polar solvent, n-octanol, were measured for a range of temperatures pertinent to the lower troposphere (273--298 ¿K). The solubility was found to be factors of 6 to 12 higher than those measured previously for pure water, ranging between 110 ¿ 7.5 M/atm at 273¿K and 34 ¿ 1.7 M/atm at 298¿K. The loss rates were found to vary from below 0.5 ¿ 10-5 sec-1 at 273¿K to 5.2 ¿ 1.9 ¿ 10-5 sec-1 at 298¿K. Several simple approaches were used to estimate that the uptake of PAN on organic aerosol has a negligible impact on ambient PAN concentrations.
