Document Summary

Chemical reactions are constantly occurring in the atmosphere- this is normal. But with the introduction of smog"s primary pollutants, sun energy (hv), and heat, new oxidizing reactions start up that create smog"s secondary pollutants. fossil fuel combustion, solvent use. No2 + hv no + o (oxygen radical formation. O + rc rco + o2 rco3 (peroxide radical formation from hydrocarbons; similar reactions occur with vocs) cycles repeat. O3 + no no2 + o2 (nitrogen dioxide formation) via sun energy) Rco3 + no no2 + rco2 (nitrogen dioxide formation) smog occurs most frequently in summer. From fossil fuel combustion & chemical solvent use: nitrogen oxides (no, no2, hydrocarbons (rc, volatile organic compounds (vocs) Formed via reactions between primary pollutants: ozone (o3, peroxyalkyl nitrate (pan, acids (including nitric and nitrous acids, other oxidant compounds (e. g. , alkyl nitrite) Smog formation takes time and moves with the air mass
