Classical smog, also known as London smog, is primarily caused by the burning of coal and other fossil fuels. It is characterized by a thick, grayish fog that contains high levels of sulfur dioxide and particulate matter.
Smog are of two types, classical or London Smog, and Photochemical Smog. Both smog comprise toxic pollutants and are reason of high mortality in areas, where such smog are common feature. London Smog/Classical Smog. Historical Perspective.
Q. Assertion :Classical smog is oxidising smog whereas photochemical smog is reducing smog. Reason: Classical smog occurs in warm, dru and sunny climate whereas photochemical smog occurs in cool humid climate.
At least two distinct types of smog are recognized: Classical smog and photochemical smog. Classical smog is also known as sulfurous smog or London smog. Sulfurous smog, which results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal .
Dec 14, 2021 · There are two main types of smog: classical smog and photochemical smog. Classical Smog: Also known as "London smog" or "sulfurous smog," classical smog is primarily composed of sulfur dioxide (SO2) and particulate matter. It occurs in cities where coal is burned for heating and industrial purposes.

Jul 13, 2024 · At least two distinct types of smog are recognized: sulfurous smog and photochemical smog. Sulfurous smog, which is also called “London smog,” results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal.
Classical smog. This is the typical form of smog found in areas which have a humid climate. It is a mixture of smoke, fog and sulphur dioxide. This smog acts as a reducing agent in atmospheric pollution and hence it is also known as reducing smog. Photochemical smog. This type of smog is prevalent in dry and sunny areas of the world.
Oct 19, 2023 · Smog is air pollution that reduces visibility. The term "smog" was first used in the early 1900s to describe a mix of smoke and fog. The smoke usually came from burning coal. Smog was common in industrial areas, and remains a familiar sight in some cities today. Today, most of the smog we see is photochemical smog.
Feb 2, 2023 · Photochemical smog, also known as ‘summer smog,’ is formed when ultraviolet (UV) light from the sun reacts with nitrogen oxides (NOx) and volatile organic compounds (VOCs). It is visible as a yellow-brown haze during the morning and in the afternoon.
