with a daily average of particulate matter PM10 above the EU limit of 50 µg/m³.
35 days are allowed in the whole year.
In 2025: 65 days above the limit, 35 allowed.
Worst day: January 14, 2026, PM10 126 µg/m³ as a daily average, 2.5 times the limit.

Yardstick: EU limits (Directive 2008/50/EC)
| Measure | 2026* | 2025 | 2024 |
|---|---|---|---|
| Days above 50 µg/m³ (allowed 35) | 28 | 65 above the number allowed | ≥ 29² |

| Days without any reading from the station | 2 | 10 | 0 |
* 2026 up to October 6; the average since the start of the year is not yet an annual average.
The monitoring networks have not yet finally verified this year’s data. The EEA publishes verified values once a year.
≥ means at least: more than a tenth of the days or hours are missing, so the real number may be higher.
² Too few readings to compare with the number allowed: the figure covers only what was measured.
Unverified hourly values of particulate matter from 975 µg/m³ up, and single spikes from 500 µg/m³ up between low values, count as missing. In the verified data for BiH from 2023 to 2025 no hour was above 600 µg/m³.
■ and a figure in red: more than is allowed for the whole year.
Compared with the new EU rules and the WHO recommendation
This is not the yardstick for the verdict above, only a comparison. From 2030 the EU tightens its limits (Directive (EU) 2024/2881), and since 2021 the World Health Organization has recommended even lower values.
- EU from 2030: daily 45 µg/m³, 18 days allowed. In 2024 there were 32 such days.
- WHO 2021: daily 45 µg/m³, at most three to four days a year. In 2024 there were 32 such days.

* 2026 up to October 6; the average since the start of the year is not yet an annual average.
The monitoring networks have not yet finally verified this year’s data. The EEA publishes verified values once a year.
Unverified hourly values of particulate matter from 975 µg/m³ up, and single spikes from 500 µg/m³ up between low values, count as missing. In the verified data for BiH from 2023 to 2025 no hour was above 600 µg/m³.
■ and a figure in red: more than is allowed for the whole year.
Compared with the new EU rules and the WHO recommendation
This is not the yardstick for the verdict above, only a comparison. From 2030 the EU tightens its limits (Directive (EU) 2024/2881), and since 2021 the World Health Organization has recommended even lower values.
- EU from 2030: daily 25 µg/m³, 18 days allowed. In 2024 there were 51 such days.
- WHO 2021: daily 15 µg/m³, at most three to four days a year. In 2024 there were 73 such days.

* 2026 up to October 6; the average since the start of the year is not yet an annual average.
The monitoring networks have not yet finally verified this year’s data. The EEA publishes verified values once a year.
¹ Fewer than 90 % of the hours were measured, so we do not compare this average with the limit.
² Too few readings to compare with the number allowed: the figure covers only what was measured.
■ and a figure in red: more than is allowed for the whole year.
There is no allowed number for the warning and alert thresholds: every such hour or day is in red.

Compared with the new EU rules and the WHO recommendation
This is not the yardstick for the verdict above, only a comparison. From 2030 the EU tightens its limits (Directive (EU) 2024/2881), and since 2021 the World Health Organization has recommended even lower values.
- EU from 2030: daily 50 µg/m³, 18 days allowed. In 2024 there were 0 such days.
- WHO 2021: daily 40 µg/m³, at most three to four days a year. In 2024 there were 0 such days.
- EU from 2030: annual average 20 µg/m³. Average in 2024: 2 µg/m³.

Outages in the last 12 months
Every period of at least 24 hours in which no reading arrived from this station.
Days without a reading: 6
4 outages, 151 hours in total in the last 12 months.
Timeline of outages from October 7, 2025 to today
| From | To | Duration |
|---|---|---|
| Jun 27, 2026 19:00 | Jun 29, 2026 12:00 | 41 hours |
| Jun 9, 2026 16:00 | Jun 10, 2026 16:00 | 24 hours |
| May 24, 2026 06:00 | May 26, 2026 16:00 | 2 days |
| Oct 28, 2025 10:00 | Oct 29, 2025 14:00 | 28 hours |
Calculated from the hourly values the EEA publishes. If late values arrive afterwards, an outage gets shorter or disappears.
Where the data comes from
Measured by Ministry of Environment and Physical Planning. We take the values from the European Environment Agency (EEA) under the CC BY 4.0 licence.
Values marked provisional have not been fully checked by the network yet. The EEA publishes verified data for the previous year once a year, usually by the end of September.
An hourly value is the average of one hour. We show the end of the hour: the value to 18:00 was measured from 17:00 to 18:00.
A day runs from midnight to midnight local time.
We only show an average when at least three out of four hours in the period have a reading. The EU air quality directive requires this for daily averages, and we apply the same rule to longer periods. We compare an annual average with the EU limit only once 90 % of hours are measured, as the directive requires. For 12 months and for a year we ask for more: if less than 90 % of hours are measured, every full calendar month needs readings for at least half of its hours. Otherwise a whole season could be missing from the average, such as summer, when ozone is highest.
We do not call a difference of up to 10 % a change, nor one of up to 1 µg/m³ at low levels, because weather and measurement uncertainty alone cause differences that size.
When a station sends no reading, the EEA sometimes fills the hour with a model estimate. We draw those hours dashed and leave them out of every average.
The EU limits come from Directive 2008/50/EC. Here they serve as a yardstick for comparison. When more than a tenth of the days or hours are missing, the number of exceedances can only be higher, so we write “at least” in front of it.
