London-type smog is caused mainly by air pollution due to combustion of coal and emission of sulphur dioxide and dust. Photochemical smog is a type of air pollution produced when sunlight acts upon motor vehicle exhaust gases to form harmful substances.
There are two major types of smog: photochemical and industrial smog. Photochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form particulate matter and tropospheric ozone. The air pollutants that are most responsible for this type of smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs). Photochemical is especially a problem in areas with many cars, coal-burning power plants, and the right weather conditions. Los Angeles, CA is a city that often has to deal with photochemical smog.
New Zeland is famous for its photochemical smog.

Photochemical smog is a type of smog made when hydrocarbons and nitrogen oxides mix with sunlight.
Photochemical smog can occur most anywhere. London-type smog comes from factories and the burning of coal and fossil fuels, where photochemical smog comes from hydrocarbons and nitrogen oxides mixing with sunlight.
New Delhi, the capital of India, is famous for its high levels of photochemical smog, especially during the winter months. This is mainly due to vehicle emissions, industrial pollution, and crop burning in the neighboring states.
Photochemical smog is formed from fossil fuel pollutants, like emissions from vehicles and industrial processes, reacting in the presence of sunlight. This type of smog is characterized by high levels of ozone and other harmful pollutants that can have negative effects on human health and the environment.
photochemical
Smog from coal fired power plants and similar is the smog "Classic" that has been with us since the start of the industrial revolution. It is sulphur dioxide and particulate in normal fog. Photochemical smog results from the action of ultraviolet light on NOx created during combustion (mostly in internal combustion engines) and reactive hydrocarbons from hydrocarbon incomplete combustion. The reaction products include:AldehydesNitrogen oxides, such as nitrogen dioxidePeroxyacyl nitratesTropospheric ozoneVolatile organic compounds

Photochemical smog is caused by the mixing of hydrocarbons and NOx in the presence of sunlight. Smog may be controlled by: * Controlling industrial emissions of the precursors * Reducing automobile emissions by reducing traffic or increasing pollution control
