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.
Industrial smog occurs when the smoke and sulfur dioxide produced from burning coal merges with fog and creates a yellowish-brown-colored haze close to ground level.
Photochemical smog forms as the result of increased usage of all fossil fuels, including gasoline and the burning of trees and organic waste. When the primary pollutants from these react with sunlight, they also form hazardous secondary pollutants.
london tpe smog forms from coal and smoke filled air. photochemical smog forms by sunlight mixing with pollutants such as hydrocarbons and nitrogen oxides.
Photochemical smog takes place with the presence of sunlight. London type of smog is caused by air pollution due to combustion of coal.
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 is caused by the action on chemicals of sunlight.
photochemical smog is formed by a complex process . photochemical smog irritates breathing passages, plants, and damage rubber,plants,and some plastics
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.
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
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
