Photochemical ozone and aerosols: models of their precursor relationships with gaseous pollutants

The paper reports results of a smog-chamber study of the relationship among photochemically derived ozone and aerosols and their gaseous precursors. Emphasis is given to the effects of irradiation time and the initial concentrations of nitrogen oxide and total NMHC on the development of ozone and aerosols. The models indicate that the concentrations of aerosols and ozone all go through maxima with respect to initial nitrogen oxide. At 2h, nitrogen oxide strongly inhibits formation, but this effect diminishes as irradiation time increases.
