Air Quality Monitor – Sarajevo

U.S. Mission BiH Air Quality Monitoring

The U.S. Embassy in Sarajevo has air quality monitoring equipment on the Embassy compound to measure fine particulate matter (commonly referred to as PM 2.5 because they are less than or equal to 2.5 microns in diameter) as an indicator of air quality in downtown Sarajevo. The results of this monitoring are available to the public on the Environmental Protection Agency’s Air Now Website. Air quality data collected at the U.S. Embassy may differ from other monitors located in Sarajevo, as data from a single monitoring station cannot be applied to an entire city.

The air quality data collected by the U.S. Mission in Sarajevo is translated into actionable information by the U.S. Environmental Protection Agency’s (EPA) NowCast algorithm. This algorithm converts raw PM 2.5 readings into an air quality index (AQI) value that reports how clean or polluted the air is and the associated health effects allowing individuals to take steps to reduce their exposure. The index is calculated based on data over a 3-12 hour period depending on the variability of particulate concentration.

Reporting on PM 2.5 is a standard recognized by the U.S. Environmental Protection Agency and allows us to compare against U.S. standard measures. For more information on PM 2.5 and air quality in general, please visit the EPA’s website. U.S. Mission Sarajevo does not track other contaminants that contribute to air pollution [e.g. coarse dust particles (PM10), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO)]. If a reading of “-999” appears for any of the U.S. Embassy’s readings, please disregard it as this indicates that the data is currently unavailable for the site in question.

Air Quality Index Levels of Health Concern Numerical Value Meaning
Good 0 to 50 Air quality is considered satisfactory, and air pollution poses little or no risk
Moderate 51 to 100 Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for Sensitive Groups 101 to 150 Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy 151 to 200 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Very Unhealthy 201 to 300 Health warnings of emergency conditions. The entire population is more likely to be affected.
Hazardous 301 to 500 Health alert: everyone may experience more serious health effects.
