Each day shows its worst measured hour, as the EEA does. “no measurement” means nothing was measured, not that the air was clean.
Who is responsible
Air quality in the Federation of BiH is monitored by three networks of stations: the federal, the cantonal and the municipal one (Air Protection Act, Official Gazette FBiH 72/24, Art. 12 to 16).
- Federal Hydrometeorological Institute (FHMZ)
- Runs the federal network, collects the data of all networks and publishes it. It issues a report every month and, every year by 31 July, the annual air quality report (Art. 14, 19 and 63).
- Canton
- Sets up the cantonal network and is responsible for the measures. When limit values are exceeded, it adopts an air quality plan. When warning or alert thresholds are at risk of being exceeded, it adopts a short-term intervention plan. When the information threshold or a concentration dangerous to health is exceeded, it informs the public (Art. 15, 22, 25, 27 and 61). In Zenica-Doboj Canton the Ministry of Physical Planning, Transport, Communications and Environmental Protection is responsible for environmental protection. The 2024 intervention plan was adopted by the Government of the canton.
- Municipality
- May run its own stations with the consent of the canton and must publish their results (Art. 16 and 17). Under the Zenica-Doboj Canton intervention plan (Official Gazette ZDK 3/24, Art. 3), the mayor of the municipality or city declares readiness based on the report of the authorised expert institution, and warning and alert based on the decision of the operational headquarters.
- Inspectorates
- The inspectorates of the Federation, the canton and the municipality supervise the law and the measures, each within its remit (Art. 71).
What the law requires when a limit is exceeded
A limit value is not a recommendation. The deadline for meeting the limit values for sulphur dioxide, nitrogen dioxide and particulate matter expired on 1 January 2021. Since then only the number of exceedances that the Pravilnik allows applies (Official Gazette FBiH 1/12, Annex X). The Air Protection Act adds that limit values, once met, must not be exceeded again (Art. 5(4)).
The law allows: for PM10 at most 35 days a year above 50 µg/m³, for sulphur dioxide at most 24 hours above 350 µg/m³ and at most 3 days above 125 µg/m³, for nitrogen dioxide at most 18 hours above 200 µg/m³ and no day with a daily average above 85 µg/m³ (Annex X).
When limits are exceeded, the canton adopts an air quality plan with measures that shorten the period of exceedance. The plan is published within eight days of adoption (Art. 8, 25, 26 and 63).
The alert thresholds are 500 µg/m³ for sulphur dioxide and 400 µg/m³ for nitrogen dioxide over three hours in a row, and 300 µg/m³ for PM10 and 280 µg/m³ for PM2.5 as a daily average (Pravilnik, Annex XIV, amended in Official Gazette FBiH 3/21). When such a situation threatens, the canton must have a short-term intervention plan. It can restrict traffic, construction work, the operation of plants and heating (Art. 27 and 28).
When the information threshold or a concentration dangerous to health is exceeded, the competent cantonal authorities inform the public through radio, television, newspapers and the internet: where, since when, how much was measured, what is expected and how to protect oneself (Art. 61 and 62).
In Zenica-Doboj Canton the procedure is set by the intervention plan (Official Gazette ZDK 3/24) in three stages: readiness, warning and alert. An alert also requires a forecast of stable weather for the next 48 hours.
The canton also has an Action Plan for Air Quality Protection from 2020 (Official Gazette ZDK 9/20), adopted under the earlier law. We could not tell from the published decision how long it applies.
We show measured values only. Whether an episode has been declared is decided by the competent authorities, who publish it on their own pages.
The limit values in BiH match the EU rules of 2008. Since 2021 the World Health Organization has recommended much lower values, for PM10 45 µg/m³ a day and 15 µg/m³ a year. From 2030 the EU lowers the annual PM10 limit to 20 µg/m³ (Directive (EU) 2024/2881).
We checked the rules against the published texts on 7 October 2026.
This year in BiH, up to yesterday (October 6)
19 of 36
monitoring stations in BiH already had more days or hours above the limit than are allowed for the whole year.
Not counted: 3 stations with too few readings to judge.
Particulate matter PM10 · 35 days above 50 µg/m³ allowed
Sulphur dioxide SO₂ · 3 days above 125 µg/m³ allowed
We count days with a daily average above the limit, from measured hours only. Where a place has several stations, the one with the most days is shown.

What the colours mean
- GoodThe air is clean. Carry on outdoors as usual.
- FairA little pollution. Carry on outdoors as usual.
- ModerateModerately polluted air. Sensitive people should take it easier outdoors if they feel symptoms.
- PoorPolluted air. Even healthy people may get sore eyes, a cough or a sore throat.
- Very poorHeavily polluted air. Sensitive people should take it easier, everyone else too if they feel symptoms.
- Extremely poorExtremely polluted air. Everyone should take it easier outdoors, sensitive people should avoid exertion.
