* In February 2015, the FNSB updated its website to coincide with EPA’s “AirNow” and the State of Alaska “Air Quality” websites by displaying the current Air Quality Index (AQI). The AQI is an index for reporting daily air quality and uses a weighted 12 hour PM concentration formula to display localized conditions. It tells you how clean or polluted your air is, and what associated health effects might be a concern for you. This will give people information that they can use to protect their health when air quality is poor, and help them get outdoors and get exercise when air quality is good. Current one hour PM 2.5 concentration values can still be found above, but should not be considered representative of a 12 or 24 hour concentration average.

AQI
(Air Quality Index)
AQI Category Cautionary Statement Health Statement
0-50 Good None None
51-100 Moderate Unusually sensitive people should consider reducing prolonged or heavy exertion. None
101-150 Unhealthy for Sensitive Groups People with respiratory or heart disease, the elderly, and children should limit prolonged exertion. Increasing likelihood of respiratory symptoms in sensitive individuals, aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly.
151-200 Unhealthy People with respiratory or heart disease, the elderly, and children should avoid prolonged exertion; everyone else should limit prolonged exertion. Increased aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly: increased respiratory effects in general population.
201-300 Very Unhealthy People with respiratory or heart disease, the elderly, and children should avoid outdoor activity; everyone else should avoid prolonged exertion. Significant aggravation of the heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly: significant increase in respiratory effects in the general population.
301-500 Hazardous Everyone should avoid any outdoor exertion; people with respiratory or heart disease; the elderly and children should remain indoors. Significant aggravation of heart or lung disease and premature mortality in persons with cardiopulmonary disease and the elderly: significant increase in respiratory effects in the general population.
