How Many Died in London Smog?

By Alice Nichols

The London Smog of 1952 was one of the deadliest air pollution incidents in history. The smog, which lasted for five days, was a combination of smoke from coal-burning factories and fog that had settled over the city. This toxic mix created a thick blanket of smog that reduced visibility to just a few feet, making it impossible to see across the street.

How Many Died?

During the smog event, thousands of people fell ill due to respiratory issues, and it is estimated that up to 12,000 people died as a result of the pollution. This death toll is shocking and serves as a stark reminder of the dangers of air pollution.

The Causes

The primary cause of the London Smog was industrial pollution. In the 1950s, coal was still widely used as a source of energy in factories and homes. The coal burned in these places released large amounts of sulfur dioxide into the atmosphere, which combined with water vapor to form sulfuric acid.

Additionally, weather conditions caused this pollution to become trapped over London. A high-pressure system had settled over the city, creating an inversion layer that prevented polluted air from rising and dispersing.

The Effects

The London Smog had far-reaching effects on public health and policy. In response to this tragedy, Britain passed new legislation in 1956 known as the Clean Air Act. This law aimed to reduce air pollution by limiting emissions from factories and homes.

In addition to its impact on public policy, the London Smog also raised awareness about air pollution’s effects on human health. It served as a wake-up call for governments around the world to take action against air pollution.

Conclusion

In conclusion, thousands died during the London Smog event in 1952 due to respiratory illnesses caused by industrial pollution mixing with fog. This tragic incident brought global attention to the devastating effects of air pollution on human health, and it led to significant policy changes aimed at reducing emissions. It serves as a reminder that we must continue to prioritize clean air and sustainable energy sources to protect public health and the environment.
