Interesting Facts About Pollution
Pollution is a global issue and one of the greatest environmental health risks of all time. Its impact is more far-reaching than what we can imagine. Here are some interesting facts about pollution to help you understand this evil better.
1. Pollution harms millions globally
Pollution kills over 100 million people worldwide. It contaminates natural resources such as air, water, and soil, leading to long-term health problems. Apart from helping diseases like malaria and HIV spread, it can cause many respiratory issues and heart conditions.
2. Polluted sites are real and exist worldwide
There are thousands of critically polluted hotspots in many countries around the world. These areas are prioritised for cleanup because the pollution severely affects surrounding communities, often causing life-threatening illnesses.
3. Children are the most affected
Children under five years old age face the highest risk of being affected by pollution. This is because their bodies are still developing organs and their immune systems are weak. Thus, they become more sensitive to toxic chemicals in water, air, and food than adults. Apart from respiratory diseases and malnutrition, exposure to high pollution can even cause death in extreme cases.
4. Pollution affects life expectancy
Living in highly polluted areas can lower life expectancy to 45 years. This happens because long-term exposure to harmful chemicals increases the risks of cancer and respiratory diseases.
5. Industries leave a polluting legacy
Contrary to popular belief, pollution factories can still pollute our planet earth even after being shut down. This is primarily because, in most cases, their harmful substances remain in the environment for many years. As a result, they continue to contaminate nearby environment including the soil and water.
6. Death rates from air pollution are highest in low-to-middle-income countries
Another fact about pollution is that low-to-middle-income countries face higher death rates as compared to other countries. For instance, sub-Saharan Africa and South Asia experience the highest death rates due to air pollution. Apart from this, indoor air pollution is also a significant issue in lower-income nations. Many people rely on materials like wood and coal for cooking in households.
7. Climate change increases air pollution
Factors such as rising global temperatures and prolonged droughts worldwide increase the frequency and severity of wildfires. These fires are a source of massive amounts of pollutants and hazardous smog.
8. Only 7 countries met WHO air quality standards in 2023
In 2023, only 7 countries including Australia, Estonia, Finland, Grenada, Iceland, Mauritius, and New Zealand stood up to WHO’s air quality guidelines. On the other hand, many countries such as Bangladesh and India exceeded WHO’s limits by more than tenfold. These alarming statistics highlight the urgent need for stricter global air quality measures.
9. Air Pollution Can Cause Lung Cancer
According to the WHO, substances like diesel engine exhaust and extremely fine particles present in the air are classified as carcinogenic. In other words, they can cause lung cancer. While short-term exposure to such particles can trigger heart attacks, long-term exposure can potentially lead to respiratory diseases and other serious health problems.

10. You can’t always see air pollution
Pollution particles in the air are finer than human hair. Their small and compact size makes it easier for them to travel deep into your lungs and bloodstream. These particles, often coming from sources like traffic and wood burning, can cause many health problems.
11. Diesel Cars Contribute to Pollution
Diesel cars release harmful gases like nitrogen dioxide (NO2), which can cause inflammation in your lungs and weaken the immune system. These cars are a major source of air pollution, especially in areas with heavy traffic.
12. London’s ULEZ is Reducing Pollution
London’s Ultra-Low Emission Zone (ULEZ) operated 24 hours a day and 7 days a week. It has been really effective in reducing pollution. How? It restricts the use of older and high-polluting vehicles out of certain areas. The ULEZ has made Outer London cleaner, reducing pollutants significantly.
