What is this Indicator?
This indicator gives a grade to each county in the U.S. based on the annual number of high ozone days. |
| Why this is important: Ozone is an extremely reactive gas composed of three oxygen atoms. It is the primary ingredient of smog air pollution and very harmful to breathe. Ozone essentially attacks lung tissue by reacting chemically with it. It also damages crops, trees and other matter -- even breaking down rubber compounds. |
| 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 average annual number of days that ozone levels exceeded U.S. 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. |
