What are the specific 8-hour Ozone (ppb) and 24-hour PM2.5 (ug/m3) concentration ranges that define 'Unhealthy for Sensitive Groups' on the Air Quality Index (AQI)? Also, what is the primary caveat regarding the quality assurance of the real-time data displayed on this website?
Navigate to the 'Air Quality Index (AQI)' page. Locate the table detailing 'How AQI ranges correspond to ozone and PM 2.5 concentrations'. Identify the numerical value, 8-hr Ozone (ppb) range, and 24-hr PM2.5 (ug/m3) range for 'Unhealthy for Sensitive Groups'. Navigate to the 'Information' page. Locate the 'Data Validity' section. Identify and state the primary caveat regarding the quality assurance of the real-time data.
State the numerical value for 'Unhealthy for Sensitive Groups' as 101-150. State the 8-hr Ozone (ppb) range for 'Unhealthy for Sensitive Groups' as 71-85. State the 24-hr PM2.5 (ug/m3) range for 'Unhealthy for Sensitive Groups' as 35.5 to 55.4. State that the real-time data presented on the website has not been quality assured and is therefore subject to change.
