Development of ph otochemical smog is typically associated wit! h specific climatical conditions and centers of high people density. Cities like Los Angeles, New York, Sydney, and Vancouver frequently touch episodes of photochemical smog. cardinal way in which the production of photochemical smog is initiated is with the photochemical reaction of nitrogen dioxide (NO2) to form oz maven. at that turn out are many sources of photochemical smog, including vehicle engines (the number peerless cause of photochemical...
