“…Peroxyacyl radicals react with nitrogen oxides to form peroxyacyl nitrates (2,16). Thus a close relationship might be expected to exist between the occurrence of the primary pollutants, nitrogen oxides and hydrocarbons, with that of the secondary pollutants, ozone and PAN.…”

“…6). This would suggest either that sufficient peroxyacyl radical existed to allow the generation of PAN to proceed after dark (16) or that an air mass moved from the downtown area of the city during the afternoon and returned in the evening to produce a~second PAN peak. Air moves along the river valley in Calgary in response to adiabatic heating and cooling.…”

“…Peroxyacetyl nitrate (PAN) and its homolog compounds (hereafter related to PANs, RC(O)OONO 2 ) are typically produced from photochemical processes involving nitrogen oxides (NO x,NO and NO 2 ) and volatile organic compounds (VOCs) (Aikin et al, 1982;Lonneman et al, 1976;Singh and Hanst, 1981). PANs are thermally unstable in the lower troposphere, but are quite stable in the upper troposphere and can be transported over long distances from the polluted continental regions into the remote troposphere (Honrath et al, 1996).…”

“…Peroxyacetyl nitrate (PAN) and its homologues (thereafter referred to PANs, RC(O)OONO 2 ) are particularly important secondary pollutants formed from photochemical reactions of volatile organic compounds (VOCs) in the presence of NO x [1][2][3][4]. These compounds are thermally unstable in the lower troposphere, but are quite stable in the mid-and upper troposphere and can be transported over long distances from the polluted continental regions into the remote troposphere [5].…”
