Photochemical smog is a type of air pollution that is formed by the reaction of sunlight with nitrogen oxides and volatile organic compounds (VOCs) in the atmosphere. Ozone is a secondary pollutant that is formed in the troposphere as a result of this chemical reaction. When nitrogen oxides and VOCs are present in the atmosphere, sunlight causes them to react and produce ozone, which is a major component of photochemical smog. Carbon dioxide and sulfur dioxide are not directly involved in the formation of photochemical smog in the troposphere. Nitrogen oxides are one of the primary components of photochemical smog along with VOCs.
