Air quality data
Last updated on May 9, 2025The state of the air around us has a direct impact on humans, wildlife, vegetation, water and soil. Poor air quality can endanger human health and the environment. Both outdoor and indoor air quality are a significant concern.
Air Quality Warnings
An air quality warning is issued when pollutant concentrations approach or exceed predetermined limits, or when degraded-air-quality episodes are expected to continue or worsen. Warnings may also be issued to implement a local or regional burning ban when the potential for seriously degraded air quality is identified.
