Air quality today

The air quality in Leoben, Styria, Austria is currently classified as Good according to the latest OpenAQ data. The dominant pollutant recorded is PM10, representing coarse particulate matter. The measured concentration of PM10 is reported at 19.46 µg/m³, which aligns with the reference value used for assessment. The concentration value of 19.46 µg/m³ is the average derived from the recent sampling interval. No other pollutants exceeded the reporting threshold in this assessment.

This rating is based on five valid observations collected from the monitoring network. All values are derived from the OpenAQ platform, which aggregates data from local sensors. The five observations were taken from distinct monitoring points within the city, providing a representative overview of ambient conditions. These observations are part of the OpenAQ aggregation that compiles measurements from certified local stations. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Leoben air‑quality feed contains six monitoring sites that together provide 28 individual data rows. All six standard pollutants tracked by OpenAQ are represented – carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm (PM10) and sulphur dioxide (SO₂). Freshness varies: seven rows have been updated within the last three days, while the remaining 21 rows are classified as old. The most recent timestamps for CO, NO₂, PM10, O₃ and SO₂ are all from 2026‑02‑10 20:00 UTC, but the NO data point dates back to 2024‑03‑11 12:00 UTC, showing a noticeable lag for that pollutant.

Across the city the measured values span a broad range. PM10 values range from a negative placeholder of –1.0 µg/m³ up to 50.68 µg/m³, with a median of 16.0 µg/m³ and the central 80 % of observations falling between 2.2 and 48.9 µg/m³. NO₂ measurements sit between 14.15 and 54.0 µg/m³, median 25.73 µg/m³, while CO values run from 167 to 345.98 µg/m³ with a median of 267.17 µg/m³. SO₂ shows a narrow band from –1.0 to 3.42 µg/m³, median 3.0 µg/m³, and O₃ varies modestly between 13.715 and 32.139 µg/m³, median 14.0 µg/m³. NO, based on only two recent rows, ranges from 4.82 to 10.78 µg/m³ with a median of 7.80 µg/m³.

The dataset is unevenly populated: PM10 enjoys nine recent rows, NO₂ eight, CO three, while NO and O₃ have only two or three rows each. Because a large share of the rows are older than three days, the snapshot may not capture short‑term fluctuations, and conditions can differ noticeably between the six sites and over time.
