Today, we're going to discuss atmospheric pollution. Can someone tell me what they think it means?

Student 1
Student 1

Is it the dirt in the air that makes it hard to breathe?

Teacher
Teacher

That’s part of it! Atmospheric pollution refers to harmful substances in our air that can affect our health and the environment. Think of it as air that's been contaminated.

Student 2
Student 2

What kind of substances are we talking about?

Teacher
Teacher

Great question! We’ll cover that soon, but first, let's remember the definition: 'Atmospheric pollution is contamination from pollutants that affect health and the environment.'

I think it's mostly nitrogen and oxygen!

Teacher
Teacher

Exactly! Air is composed of 78% nitrogen, 21% oxygen, and small amounts of other gases like carbon dioxide. Pollutants mix in with these gases and impact our health.

Definition of Atmospheric Pollution

Unlock Audio Book

Signup and Enroll to the course for listening the Audio Book

Atmospheric pollution refers to the contamination of air due to the presence of harmful substances (pollutants) that affect the health of living organisms and the environment.

Detailed Explanation

Atmospheric pollution occurs when harmful substances, known as pollutants, enter the air and make it unsafe. These pollutants can originate from various sources, including vehicles, factories, and natural events. The presence of these pollutants can lead to serious health issues for both humans and other living organisms, as well as damaging the environment. For instance, when air is polluted, it can affect our ability to breathe, contribute to diseases, and cause harm to plants and animals.

Examples & Analogies

Think of the air in a city like a big glass of water. If you drop in some dirt or oil, the water becomes polluted and unsafe to drink. Similarly, when harmful substances mix with the air we breathe, it becomes polluted and can potentially harm our health.
