Nitric acid is ubiquitous in the atmosphere, as a sequestering agent for NOx and HOx. Its primary fate in the lower atmosphere is to dissolve into the aqueous phase; nitrate is also present in atmospheric aerosols and urban films. Illumination of aqueous systems containing nitrate and PAH with actinic radiation gives rise to a rapid loss of the PAH. The results of kinetic and product identification studies of this process taking place on the water and ice surfaces are presented. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
