How Many Died in the Great Smog of London?

By Alice Nichols

The Great Smog of London was a severe air pollution event that occurred in December 1952. It lasted for almost a week and caused an estimated 4,000 deaths in the city. The smog was so thick that it reduced visibility to just a few meters, disrupted transportation, and forced people to stay indoors.

What Caused the Great Smog of London?

The Great Smog of London was caused by a combination of factors, including weather conditions and human activities. The weather conditions at the time were perfect for trapping pollutants in the air. A high-pressure system had settled over London, which created an inversion layer that prevented the polluted air from rising and dispersing.

Human activities also played a significant role in causing the smog. At that time, most households in London relied on coal for heating and cooking.

Coal-powered factories and power plants also contributed to the pollution. The use of low-quality coal with high sulfur content exacerbated the problem.

How Many People Died?

The exact number of people who died as a result of the Great Smog is difficult to determine due to various factors such as delayed onset of symptoms, underreporting, etc. However, estimates suggest that around 4,000 people died during and after the smog event.

The Immediate Impact

In the immediate aftermath of the smog event, hospitals were overwhelmed with patients suffering from respiratory problems such as bronchitis, pneumonia, and asthma attacks. The death toll continued to rise for weeks after the smog cleared as many people developed complications from exposure to pollutants.

The Long-Term Impact

The Great Smog of London led to significant changes in legislation aimed at reducing air pollution levels in cities across Europe. In 1956, Parliament passed the Clean Air Act which banned coal burning in urban areas and required industries to reduce emissions.

  • Long-Term Health Effects: The long-term effects of exposure to air pollution from the Great Smog of London are still being studied. Research has linked air pollution to a range of health problems, including lung cancer, heart disease, and respiratory illnesses.
  • Economic Impact: The Great Smog of London had a significant economic impact on the city. It disrupted transportation, closed schools and businesses, and caused damage to buildings and infrastructure.

Conclusion

The Great Smog of London was a tragic event that highlighted the dangers of air pollution. It led to significant changes in legislation aimed at reducing pollution levels in cities across Europe.

However, the long-term effects of the smog are still being felt today, with research linking air pollution to a range of health problems. It is crucial that we continue to take steps to reduce our impact on the environment and protect public health.
