Photochemical oxidants definition

Photochemical oxidants means an air pollutant, which is formed by the action of sunlight on oxides of nitrogen and hydrocarbons.
Photochemical oxidants means substances produced in the atmosphere where as a result of exposure of certain active chemical compounds, principally the hydrocarbons and nitrogen oxides, to sunlight. For the purpose of these standards, the photochemical oxidants shall include the ozone, peroxyacyl nitrates, organic peroxides and other oxidants which contribute to the increase of oxidants concentration as measured by the method specified in paragraph C of Article 11.
