Sarajevo recorded an Air Quality Index (AQI) of 305 at 5:00 pm on Monday, categorizing the air as hazardous. PM10 particle levels reached 276 µg/m³, significantly exceeding the safe 24-hour average of 50 µg/m³. Residents are advised to avoid outdoor exertion, with vulnerable groups, including pregnant women, children, the elderly, and individuals with heart or respiratory conditions, urged to stay indoors.

PM10 particles, primarily from solid fuel combustion, vehicle emissions, and industrial activity, pose severe health risks. Symptoms may worsen for those with respiratory conditions such as asthma.
Other affected areas include Ilijas and Travnik, where AQI levels reached 211 and 261, respectively. Nationwide air quality monitoring, conducted by various governmental and non-governmental bodies, highlights the growing environmental health challenge in Bosnia and Herzegovina.
Fine particles (PM2.5), even smaller and more dangerous, are also prevalent, originating from fossil fuel combustion and containing harmful elements like lead and heavy metals. Immediate precautions are necessary to protect public health amid these alarming conditions.
