How often the air is above the limit

For every official monitoring station in BiH: on how many days or hours a year the air was above the legal limit, and how many are allowed. Only measured values count.

25 of 33

stations in BiH were over the number allowed in 2023

Not counted: 1 station with too few readings to judge.

116

most days with PM10 above the limit: Ilijaš

most days with SO₂ above the limit: Visoko

The whole of 2023.

O₃ · days with an 8-hour average above 120 µg/m³ · target value 25

For ozone the 25 days are a target value averaged over three years, not a limit for a single year.

A day runs from midnight to midnight local time; a daily average needs at least 18 of 24 hours measured. Model estimates do not count.

≥ means at least: the station is missing more than a tenth of the days or hours, so it ranks lower than it would with complete readings.

Grey at the end: stations with 0 but too few readings, and, marked ³, stations whose unverified hourly values jump unusually strongly. We compare neither with the allowed number.
