Abstract

The auto exhaust was irradiated with xenon light or solar light under static conditions, and the concentration changes of hydrocarbons, nitrogen oxides, formaldehyde and irradiation products were analysed. The concentrations of each component were determined by hydrogen flame ionization gas chromatography for hydrocarbons, and colormetry for nitrogen oxides and formaldehyde, and electron capture gas chromatography for irradiation products, respectively. From these experiments, it was noticed that the concentrations of hydrocarbons and nitrogen oxides decreased, whereas that of formaldehyde increased. The irradiation products were also found to be methyl nitrite, ethyl nitrite, methyl nitrate, ethyl nitrate, n-propyl nitrate, isobutyl nitrate, biacetyl and PAN. Therefore these photochemical reactions of auto exhaust were assumed to occur in the atomosphere.
