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 is this 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.
