Why Outdoor Air Quality Matters

Outdoor air quality plays a vital role in our health and environment. Pollutants from vehicle emissions, industrial processes, construction dust, and wildfire smoke can make the air harmful to breathe, particularly during certain weather conditions or seasons. Poor outdoor air quality can trigger respiratory irritation, allergies, asthma, fatigue, and even long-term heart and lung problems. Children, older adults, and individuals with pre-existing conditions are especially vulnerable to its effects.

Monitoring key outdoor air quality indicators helps identify pollution sources and encourages healthier choices—such as adjusting outdoor activities, supporting cleaner transportation, and promoting greener urban planning. By understanding and improving the air we share, we can create a healthier, more sustainable environment that benefits communities and ecosystems alike.
