Naphthalene and biphenyl are two polycyclic aromatic hydrocarbons (PAH) present in ambient air, and their atmospheric chemical removal processes are known to be via gas-phase reactions with the OH radical and with N/sub 2/O/sub 5/. The kinetics of the gas-phase reaction of N/sub 2/O/sub 5/ with naphthalene and biphenyl have been investigated, and the products of their reactions with the OH radical in the presence of NO/sub x/ and with N/sub 2/O/sub 5/ have been studied. The rate constant for the reaction of naphthalene with N/sub 2/O/sub 5/ at 298 +- 2 K was determined to be (1.4 +- 0.2) x 10/sup -17/ cm/sup 3/ molecule/sup -1/ s/sup -1/. The 1- and 2-nitronaphthalene products formed in the reactions of naphthalene with N/sub 2/O/sub 5/ and with the OH radical in the presence of NO/sub x/ were determined to have yields of 0.153 +- 0.022 and 0.0032 +- 0.0028 for 1-nitronaphthalene, respectively, and 0.069 +- 0.021 and 0.0027 +- 0.0034 for 2-nitronaphthalene, respectively. The OH radical initiated reaction of naphthalene also produced the 1- and 2-naphthols. Biphenyl was observed to react only with the OH radical, with 2-hydroxybiphenyl (yield 0.204 +- 0.078) and 3-nitrobiphenyl (yield 0.047 +- 0.034) being the major products identified and quantified. The nitroarene products and yields are consistent with ambient air measurements and suggest that many, if not most, of the nitroarenes observed in ambient air are formed from their parent PAH via atmospheric reactions
