During the Great Smog of 1952 in London, which lasted for several days in December, millions of people were affected by severe air pollution caused by coal burning and weather conditions. Many stayed indoors to avoid the toxic air, while public transport ground to a halt. In response to the disaster, which led to thousands of premature deaths, the British government implemented the Clean Air Act of 1956, which aimed to reduce smoke emissions and improve air quality through regulations on coal burning and the establishment of smokeless zones.

Smog.
because of all of the smog (pollution)
Large cities often face serious smog problems due to high levels of vehicle emissions and industrial pollution, both of which release significant amounts of pollutants into the atmosphere. Additionally, geographical factors such as temperature inversions can trap these pollutants close to the ground, exacerbating air quality issues. Urban density and limited green spaces further contribute to the accumulation of smog, making it difficult for cities to disperse harmful particles.
It was estimated that 4,000 people died and 100,000 were made ill
Great Smog happened in 1952.
In the Great Smog of 1952 in London, it is estimated that around 12,000 people died prematurely due to the effects of the smog. The exact number of deaths directly caused by the smog is difficult to determine, as many deaths were attributed to respiratory issues exacerbated by the pollution.

It no longer exists/happens but in the days when London houses used coal fires to heat homes, the coal smoke mixed with normal fog to produce what was called "smog" (smoke and fog). It was very thick and very bad for health. London no longer has "smog" events because it no longer allows chimneys to emit smoke.
Smoke and fog
'Snog' is a combination of the words smoke and fog. London used to be a huge manufacturing centre with coal-fired factories belching smoke into the atmosphere and most people heated their houses with coal fires in the days before central heating. The last great smog was in 1961 after the passing of the Clean Air Act which restricted people and businesses in the type of fuel that they could burn.
The duration of smog events can vary significantly depending on the specific incident and location. For example, the Great Smog of London in December 1952 lasted about five days, while other smog occurrences may last from a few hours to several days. Factors such as weather conditions, pollution sources, and geographic features all influence how long smog persists.
The Great London Smog (SMoke + fOG) was the result of coal smoke from fired heating during an unusual cold period combining with the heavy fogs of London. Although smog was not uncommon in London this was an unprecedented event, it lasted from Friday 5 December to Tuesday 9 December 1952. The coal smoke contained sulfur dioxide ans a well as organic (coal tar) compounds which made the mixture acidic and resulted in breathing problems for many. About 4,000 people were known to have died as a result of the fog, this estimate could be considerably loweer than the actual number.
Classical smog was first discovered in London, England, during the early 20th century. The term became widely used following severe air pollution events, particularly the Great Smog of 1952, which resulted from a combination of industrial emissions and weather conditions. This smog was characterized by a dense mixture of smoke and fog, highlighting the health risks associated with air pollution.
Smog, a combination of smoke and fog, was first identified as a significant environmental issue in the early 20th century. The term itself gained prominence in the 1900s, particularly in London, where severe air pollution incidents, such as the Great Smog of 1952, highlighted its dangers. This event led to increased awareness and regulatory measures regarding air quality and pollution.
There hasn't been a smog in London for about 50 years.
