Air Quality Forecast For Saturday Apr 13 2024





                                     LEVEL OF

STATION              COLOR        HEALTH CONCERN         POLLUTANT



Tri-Cities TN        Green           Good                   OZ



Knoxville TN         Yellow          Moderate               OZ



GSMNP                Yellow          Moderate               OZ



Chattanooga TN       Green           Good                   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.
