The effects of air pollution on human health can vary depending on the pollutants and the level of exposure to them.

Exposure to certain pollutants increases the risk of diseases such as lung cancer, asthma, and heart disease.

People who already suffer from illnesses are often the most affected by air pollution, but everyone should be aware of the dangers.

The tiniest particulate matter (PM2.5) can cause severe health effects. These particles are so small that they can easily penetrate the lungs and affect the health of the respiratory system.

They can also lead to heart attacks and even cause premature death. In addition, exposure to PM2.5 may impair the development of children.

Air pollutants can also cause diseases, birth defects, and lower reproductive rates in animals.

Many air pollutants contain carbon dioxide, a greenhouse gas that is harmful to humans.

Exposure to this gas is associated with increased risk of heart attacks, stroke, and asthma, as well as a number of cancers.

The two main components of air pollution are smog and nitrogen oxide.

The former is produced by vehicles and is also known as smog. It forms in high concentrations around highways, where it reacts with sunlight.

Both types of pollutants can cause bronchitis, asthma, and heart disease.
