The Air We Breathe: Composition of Air, Pollution and Its Effects, etc.
Introduction:
The air we breathe is essential to our survival, but it’s important to understand what exactly makes up the air we breathe and how pollution can impact its composition. In this article, we will explore the composition of air, types of pollution, and their effects on our health and environment.
Composition of Air:
Air is made up of several gases, including nitrogen (78%), oxygen (21%), argon (0.9%), and carbon dioxide (0.04%). There are also small amounts of other gases present, such as neon, helium, methane, and ozone. Additionally, air contains water vapor, dust, and microscopic particles.
Pollution:
Pollution is the presence or introduction of harmful substances into the environment. There are several types of pollution that can impact the quality of the air we breathe, including:
-
Particulate Matter (PM) – Tiny particles in the air that can come from sources such as car exhaust and wildfires. These particles can cause respiratory issues and increase the risk of heart disease and lung cancer.
-
Ground-Level Ozone (O3) – A harmful gas formed when sunlight reacts with chemicals from car exhaust and industrial emissions. Ozone can cause respiratory issues and worsen breathing problems.
-
Carbon Monoxide (CO) – A colorless and odorless gas that is toxic to humans and animals. It is often produced by cars and can cause headaches, dizziness, and nausea.
-
Sulfur Dioxide (SO2) – A gas produced by burning fossil fuels that can cause respiratory problems, especially in people with asthma.
Effects of Pollution:
The effects of pollution on our health and environment can be severe. Exposure to polluted air can lead to respiratory issues, heart disease, strokes, and even cancer. Pollution can also impact ecosystems, leading to the extinction of certain species and compromising the quality of soil and water.

Conclusion:
It’s crucial that we understand the composition of air and the impact pollution can have on our environment and health. By reducing our contribution to pollutants and advocating for policies that promote clean air, we can help protect ourselves and future generations from the harmful effects of pollution.
