What are pollutants?

Pollutants are solid, liquid, or gaseous substances that when present at a certain concentration threshold, affect living organisms in the environment negatively.

In other words, a substance cannot be labeled a pollutant until it reaches a concentration level that is harmful to living organisms.

Thus, carbon dioxide is a natural component of air at a normal concentration. Once the concentration level increases and it starts affecting the environment negatively, it becomes a pollutant.
