Corrosionpedia explains Photochemical Oxidant

Examples of photochemical oxidants are:

  • Ozone
  • Hydrogen peroxide
  • Peroxyacetyle nitrate

These compounds are hazardous air pollutants and are the fundamental reactants required for the formation of smog. Generally, photochemical oxidants are chemical or physical contaminants that may be responsible for the onset of significant health problems. These pollutants may be the byproducts of corrosion activities such as rust or particulate matter.

Strict industrial guidelines are in place to prevent accidents from occurring when working with or producing hazardous photochemical oxidants.
