PANs are a secondary pollutant since they form in the atmosphere after the emission of primary pollutants. Dr. Emily Fischer uses these data to better understand how pollutants move in the lower atmosphere. Data Access. These pollutants cause acid rain. Peroxyacetyl nitrate (PAN) is formed via the oxidation or photolysis of oxygenated volatile organic compounds (oVOCs) in the presence of NO 2 [1-2].PAN is phytotoxic in high concentrations [3-4], and is a powerful lachrymator formed in photochemical air pollution [5-6].It can allow NO x to be sequestered and transported over long distances and then be released under high . PAN influenced the plant water potential of PAN-sensitive 'Provider' resulting in visible wilting and reduced soil moisture content. The reaction of acetaldehyde with the OH free radical in urban atmospheres leads directly to the formation of the peroxyacetyl radical which in turn reacts with NO2 to form peroxyacetyl nitrate (2).
