What is this Indicator?
This indicator gives a grade to each county in the U.S. based on the average annual number of days that exceed U.S. particle pollution standards (PM2.5). |
| Why this is important: Particle pollution refers to the amount of particulate matter in the atmosphere. Inhaling particulate matter can adversely affect health through illnesses such as asthma or cardiovascular problems, or premature death. The smaller the particulate matter, the more hazardous it is to health. |
| Technical Note: The American Lung Association (ALA) assigns grades A-F to counties (A=1; B=2; C=3; D=4; F=5), based on the number of days that particle pollution exceeded US standards during the three year measurement period. The five-point grading scale was used for the distribution (Green = <2; Yellow = 2 - 3; Red = >3). The air quality data is collected by the EPA and summarized by the ALA. |
