What was the Great Smog of London?

Back

The Great Smog of London was a severe air pollution event that occurred in December 1952, caused by coal burning and weather conditions.

Front

What are the health effects of smog pollution?

Back

Smog pollution can cause respiratory issues, cardiovascular diseases, and can exacerbate existing health conditions.

Front

How does coal contribute to smog pollution?

Back

Coal combustion releases sulfur dioxide and particulate matter, which contribute to the formation of smog.

Front

What measures were taken to reduce smog pollution after the Great Smog?

Back

The Clean Air Act of 1956 was enacted in the UK to regulate emissions and improve air quality.

Front

What is the role of temperature inversions in smog formation?

Back

Temperature inversions trap pollutants close to the ground, preventing them from dispersing and leading to increased smog levels.

Front

How can smog affect visibility?

Back

Smog reduces visibility by scattering and absorbing light, making it difficult to see through polluted air.

Front

What is the difference between industrial smog and photochemical smog?

Back

Industrial smog is primarily caused by coal burning and industrial emissions, while photochemical smog results from sunlight reacting with pollutants like nitrogen oxides and volatile organic compounds.

Front

What are some long-term effects of exposure to smog?

Back

Long-term exposure to smog can lead to chronic respiratory diseases, lung cancer, and reduced lung function.
