Air Quality Forecast For Friday Jun 28 2024 LEVEL OF STATION COLOR HEALTH CONCERN POLLUTANT Tri-Cities TN Yellow Moderate OZ Knoxville TN Yellow Moderate PM GSMNP Yellow Moderate PM Chattanooga TN Yellow Moderate OZ PM = Particulate Matter OZ = Ozone The six levels of health concern: Good (Green): Air quality is considered satisfactory, and air pollution poses little or no risk. Moderate (Yellow): Air quality is acceptable, however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms. Unhealthy For Sensitive Groups (Orange): Members of sensitive groups may experience health effects. This means they are likely to be affected at lower levels than the general public. For example, people with lung disease are at greater risk from exposure to ozone, while people with either lung disease or heart disease are at greater risk from exposure to particle pollution. The general public is not likely to be affected when the AQI is in this range. Unhealthy (Red): Members of sensitive groups may experience more serious health effects. Very Unhealthy (Purple): Everyone may experience more serious health effects. Hazardous (Maroon): The entire population is more likely to be affected.
