Air at the Berovo station
Berovo, North Macedonia
Network: Ministry of Environment and Physical Planning · Station code: MK0053A
This year, up to yesterday (October 6)
at least
3 days
with a daily average of particulate matter PM10 above the EU limit of 50 µg/m³.
Readings are missing for part of the period, so the real number may be higher.
at least
1 day
with an 8-hour average of ozone (O₃) above the target value of 120 µg/m³.
Readings are missing for part of the period, so the real number may be higher.
Worst day: March 17, 2026, PM10 55 µg/m³ as a daily average, 1.1 times the limit.

How the air is changing
There are not enough readings to compare with the week before.
- PM10: too few readings to compare
- PM2.5: too few readings to compare
- NO₂: too few readings to compare
- O₃: too few readings to compare
- SO₂: too few readings to compare
Last month there was less PM10 and O₃ in the air than the month before.
- PM10: average 19.7 µg/m³, month before 23 µg/m³
- PM2.5: average 10.8 µg/m³, month before 11.6 µg/m³
- NO₂: average 4.2 µg/m³, month before 3.6 µg/m³
- O₃: average 58.9 µg/m³, month before 72.1 µg/m³
- SO₂: too few readings to compare

* 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.

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 2025 there were 0 such days.
- WHO 2021: daily 25 µg/m³, at most three to four days a year. In 2025 there was 1 such day.
- EU from 2030: annual average 20 µg/m³. Average in 2025: 8 µg/m³.
- WHO 2021: annual average 10 µg/m³. Average in 2025: 8 µg/m³.

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 2025 there were 0 such days.
- WHO 2021: daily 40 µg/m³, at most three to four days a year. In 2025 there were 0 such days.
Sources: Directive (EU) 2024/2881, Annex I; WHO global air quality guidelines 2021, table 0.1. Checked against the texts on 7 October 2026.
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: 5
1 outage, 127 hours in total in the last 12 months.
Timeline of outages from October 7, 2025 to today
| From | To | Duration |
|---|---|---|
| Oct 1, 2026 12:00 | Oct 6, 2026 19:00 | 5 days |
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.
