The AQI was developed to provide a simple, uniform way to report daily air quality conditions.
An index of biological integrity (IBI) is a particularly powerful tool that provides an accurate measure of the condition of the biological communities and are a direct determinant of the attainment of aquatic life uses.
Understanding small-scale differences in air pollution is important for minimizing exposure to harmful air pollutants, particularly for vulnerable communities.
Minnesota’s air currently meets all federal air quality standards. However, even levels of air pollution below the standards can affect people’s health, including levels currently found in parts of Minnesota.
The MPCA's air monitors continually measure pollutants. With this data, the agency can track pollution trends over time and show if outdoor air meets air quality standards and health benchmarks.
Air sensors are instruments that measure air quality conditions in near real time.
