London smog is found in
Answers
The Great Smog of London, or Great Smog of 1952 was a severe air-pollution event that affected the British capital of London in early-December 1952. A period of cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants – mostly arising from the use of coal – to form a thick layer of smog over the city. It lasted from Friday, 5 December to Tuesday, 9 December 1952 and then dispersed quickly when the weather changed.
It caused major disruption by reducing visibility and even penetrating indoor areas, far more severe than previous smog events experienced in the past, called "pea-soupers". Government medical reports in the following weeks, however, estimated that up until 8 December, 4,000 people had died as a direct result of the smog and 100,000 more were made ill by the smog's effects on the human respiratory tract. More recent research suggests that the total number of fatalities was considerably greater, about 12,000.[1]
The Prime Minister at that time, Winston Churchill, was adamant that it would pass, simply dismissing it as a "weather event".
here is your answer
December 1952, London was trapped in a deadly cloud of fog and pollution for five days — what became known as the Great Smog of 1952
London was trapped in a deadly cloud of fog and pollution for five days. At the time, the city ran on cheap coal for everything from generating power to heating homes. So when an anticyclone caused cold air to stagnate over London, the sulfur dioxide, carbon dioxide, and smoke particles mounted — and ended up choking as many as 12,000 people to death.
