Introduction to the Great Smog of London
The Great Smog of London, also known as the Big Smoke, was a severe air pollution event that took place from December 5 to December 9, 1952. During this period, a thick, choking fog enveloped the city, causing respiratory problems, disrupting transportation, and claiming thousands of lives. The smog was so dense that it reduced visibility to just a few feet, making it difficult for people to navigate the streets. The disaster was a wake-up call for the British government, leading to the implementation of stricter air pollution controls and the eventual passage of the Clean Air Act in 1956.
Causes of the Great Smog
The Great Smog of London was caused by a combination of factors, including weather conditions, industrial pollution, and domestic coal burning. A high-pressure system had settled over the city, creating a temperature inversion that trapped cold air close to the ground. This led to a buildup of pollutants, including sulfur dioxide, nitrogen oxides, and particulate matter, which were emitted by factories, power plants, and homes burning coal for heat. The resulting smog was a toxic mixture of these pollutants, which had devastating effects on the health of London’s residents.
The Role of Sulfur Dioxide
Sulfur dioxide (SO2) was a key pollutant responsible for the Great Smog of London. SO2 is a colorless, odorless gas that is emitted when fossil fuels, such as coal and oil, are burned. In the presence of water and oxygen, SO2 can react to form sulfuric acid, which can cause respiratory problems and damage to buildings and vegetation. During the Great Smog, the high concentrations of SO2 in the air led to the formation of sulfuric acid, which contributed to the smog’s toxic effects.
