Due to the change in weather conditions, the air quality in the capital of Bosnia and Herzegovina, which has been among the most polluted cities in the world in recent days, has significantly improved.
According to measurements this morning at 8.00 am, the air quality is good, and the measured air quality index was 21.
At some measuring stations, the air quality index ranges from 0 in Otoka, to 20 and 21 at the measuring stations of the US Embassies and Ilidža, Fena news agency writes.
The air quality index is based on the measurement of particulate matter (PM2.5 and PM10), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2) and carbon monoxide (CO) emissions.
In the past seven days, the air quality in Sarajevo was very unhealthy, the air quality index ranged from 168, as measured on December 29, to 230, as it was on January 2, when the concentration of PM2.5 particles in the air was registered.
PM2.5 particles are formed by burning fossil fuels (car exhaust, wood or coal heating, etc.) and consist mainly of sulfates, nitrates, ammonia, organic and elemental carbon, heavy metals such as lead, manganese, copper, cadmium, zinc, nickel, vanadium and chromium.
