The Air Quality Index is between 51 and 100, meaning that the air quality is acceptable in Eastern Iowa after almost a week of unhealthy to very unhealthy levels due to the Canadian wildfire smoke. While the air quality is deemed acceptable, pollution in this range may pose a moderate health concern for a very small number of individuals. People who are unusually sensitive to ozone or particulate pollution may experience respiratory symptoms. You can find more information on the Air Quality Index at Airnow.gov.
