The Great Smog Of London

The Great Smog of London, also known as the Big Smoke, was a severe air pollution event that

occurred in London, England, in December 1952. It was one of the deadliest environmental disasters in history and had a big impact on public health.

 

The smog event lasted for five days, from December 5 to December 9, 1952. It was characterized by a combination of cold weather, fog, and a high concentration of pollutants in the air, primarily from coal burning for domestic heating and industrial activities. The smoke and sulfur dioxide emissions from coal combustion mixed with the fog to create a thick, yellowish smog that blanketed the city.

The smog severely affected visibility, causing traffic accidents and disrupting transportation. The high levels of pollutants, particularly sulfur dioxide and particulate matter, led to respiratory problems and exacerbated existing health conditions. Thousands of people fell ill, and the smog is estimated to have caused the premature deaths of at least 4,000 people in the short term. Long-term effects on health, such as respiratory diseases, were also observed.

The Great Smog of London served as a wake-up call regarding the dangers of air pollution and its impact on public health. It led to significant changes in environmental legislation and policies. The Clean Air Act was passed in 1956, which introduced measures to control and reduce air pollution, including the relocation of power stations away from urban areas and the promotion of smokeless fuels.

The event also raised awareness about the need for international cooperation on environmental issues. The Great Smog of London influenced discussions on air pollution and led to the establishment of the first international air pollution conference in 1955.

Overall, the Great Smog of London was a tragic event that had a lasting impact on public health, urban planning, and environmental policy. It served as a catalyst for significant changes in pollution control measures and contributed to the recognition of air pollution as a global environmental issue.
