Nitronaphthalenes atmospheric formation

Nitroarenes were formed under laboratory conditions when PAH reacted with gas-phase OH radical (in presence of NO ) and N2O540 45. The atmospheric nitroarene formation rate depends upon the concentration of the individual species N2O5-NO3-NO2 An analogous reaction sequence occurs when PAH reacts in N2O5-NO3-NO2 systems46. Naphthalene reacts with NO3 radical forms NO3-naphthalene adduct, which dissociates or reacts with NO2 to form nitronaphthalene and other products as shown in Figure 6.
