Answer:

Explanation:
Air pollution and its effects: The air pollutants that cause diseases are "criteria air pollution".
- They are the most abundant in the atmosphere. They damage human health.
- Air pollutants are ozone, nitrogen dioxide, particulate matter, lead, carbon monoxide, sulphur.
- Lead damages the nervous system, kidneys, and brain.
- Particulate matter pollution is the main source of diseases.
- Particulate matter includes tiny particles of liquids, solids that exist in the air. They are so small that they penetrate into the lungs and bloodstream.
- Ozone is toxic when it is at the ground level. In reaction with sunlight and heat, it forms volatile organic compounds.
- Sulphur dioxide and nitrogen dioxide are released due to the combustion of fossil fuels and industrial processes. Both damage the lungs and airway, which leads to the exacerbation of cardiovascular disease.
- Nitrogen dioxide causes asthma.
- Carbon monoxide comes from the incomplete burning of fossil fuels.
- It prevents having a sufficient amount of oxygen in the air. Less oxygen causes confusion, nausea and even death.
Hence, air pollutants in the air cause diseases that are life-threatening.
