Photochemical oxidants

The photochemical oxidants are secondary air pollutants formed by the action of sunlight on nitrogen oxides and reactive hydrocarbons, their precursors. The most important phytotoxic components produced by these atmospheric photochemical reactions are ozone and peroxyacetyl nitrate. In the troposphere, it is formed through a complex series of . Ozone (O3) is a strong oxidizing agent. Sources of photochemical oxidants and their precursors 1.

Environmental concentrations and exposures 1. Effects on experimental animals 1. The reaction is induced by or accelerated by exposure to electromagnetic. Review and cite PHOTOCHEMICAL OXIDANTS protocol, troubleshooting and other . Air pollutants formed by the action of sunlight on oxides of nitrogen and hydrocarbons. They can be formed as the result of the sunlight induced oxidation . In the context of this report, photochemical oxidants are understood to include ozone, nitrogen dioxide, and peroxyacylnitrates. Many other compounds have .
