23 of 28 countries in this AEI comparison have a lower annual PM2.5 average. Lower means closer to the WHO 2021 health guideline of 5 µg/m³; absolute volume is not a legal compliance score.
EEA country evidence profile
Croatia's high-exposure position
PM2.5 rank #4 of 28
Croatia's EEA Average Exposure Indicator is 14.4 µg/m³, or 2.9× the WHO 2021 annual guideline. Among the EU+UK countries in this dataset, 23 have a lower PM2.5 average. Its widest WHO-guideline gap is PM2.5 at 2.9×.
The EEA's 2022 burden series places Croatia at #3 of 27 for modeled PM2.5-attributable deaths per 100,000 people (95.7). Here, the exposure and per-capita burden ranks sit in a similar part of this dataset. This compares two published population-level indicators; it is not a measure of an individual's exposure or risk.

Figures on PlainAirQuality are rendered from this site's database rather than typed into the page. Country values restate the EEA's published series and are held in our dataset pending an automated re-import; station-level values are modelled from those national means, not measured at the station. Country PM2.5 restates the EEA Average Exposure Indicator (AEI) 2023; mortality restates the EEA Burden of Disease 2022 series; country PM10/NO2/O3/SO2 means are editorial composites pending verified ingest; station-level values shown elsewhere are modelled from the national PM2.5 AEI (methodology §5b), not independently measured.
