2010 Air pollution-particulate matter days

Summary Information

Range in Minnesota (Min-Max): 0-3
Overall in Minnesota: 1
Target Value: 0 (90th percentile)

Ranking Methodology

Summary Measure: Health Factors – Physical Environment (Air Quality)
Weight in Health Factors: 2.5%
Years of Data Used: 2005
Map ↓
The counties are shaded with lighter counties having a better rank. Gray counties are not reported (NR).
What It Is:

The air pollution—particulate matter measure represents the annual number of days that air quality was unhealthy for sensitive populations due to fine particulate matter (FPM, < 2.5 µm in diameter).

Where It Comes From:

The Public Health Air Surveillance Evaluation (PHASE) project, a collaborative effort between the Centers for Disease Control and Prevention (CDC) and the EPA, used Community Multi-Scale Air Quality Model (CMAQ) output and air quality monitor data to create a spatial-temporal model that estimated fine particulate matter concentrations throughout the year. The PHASE estimates were used to calculate the number of days per year that air quality in a county was unhealthy for sensitive population due to FPM.  The state and national values are an average of county values weighted by population size.

Reason for Ranking:

The relationship between elevated air pollution—particularly fine particulate matter and ozone—and compromised health has been well documented. The negative consequences of ambient air pollution include decreased lung function, chronic bronchitis, asthma, and other adverse pulmonary effects.
