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.
There hasn't been a smog in London for about 50 years.
London-type smog is caused mainly by air pollution due to combustion of coal and emission of sulfur dioxide and dust. London smog has humid, foggy, stagnant air.
Interesting and very difficult to put into x amount of letters.
The Great Fire of London did start in Puddings Lane.
Great Smog happened in 1952.
It was estimated that 4,000 people died and 100,000 were made ill
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.

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.
