Air Quality
Definition
Air quality refers to the condition of the air in terms of its level of pollution. It measures the presence of harmful substances such as pollutants, chemicals, or particles in the atmosphere that can impact human health or ecosystems.
Analogy
Think of air quality as a swimming pool. Just as you want clean water without contaminants when swimming, good air quality means breathing clean, fresh air without harmful substances present.
