Photochemical smog is a mixture of air pollutants which have been chemically altered into further noxious compounds by exposure to sunlight. The main components of photochemical smog are nitrogen oxides, Volatile Organic Compounds (VOCs), tropospheric ozone, and PAN (peroxyacytyl nitrate).
Correspondingly, what does photochemical smog consist of?
Photochemical smog is the chemical reaction of sunlight, nitrogen oxides and volatile organic compounds in the atmosphere, which leaves airborne particles and ground-level ozone. This noxious mixture of air pollutants may include the following: Aldehydes. Nitrogen oxides, particularly nitric oxide and nitrogen dioxide.
What is photochemical smog made up of?
That mixture of bad chemicals is called photochemical smog. The chemicals in photochemical smog include nitrogen oxides, Volatile Organic Compounds (VOCs), ozone, and PAN (peroxyacytyl nitrate). Nitrogen oxides mostly come from the engines of cars and trucks.
What are some examples of primary pollutants?
- carbon monoxide (CO) odorless, colorless, poisonous gas.
- oxides of nitrogen (NOx, NO) NO - nitric oxide.
- sulfur oxides (SOx) SO2 - sulfur dioxide.
- volatile organic compounds (VOCs) highly reactive organic compounds.
- particulate matter (dust, ash, salt particles) bad for your lungs.
