Air quality today

The air quality today in Voitsberg, Styria, Austria is classified as Good. The main pollutant is PM10. Three valid measurements were recorded, showing a PM10 concentration of 28.0 µg/m³. This value corresponds closely to the reference level of 28.0222931 µg/m³. No PM2.5 reference value is provided.

The data displayed are sourced from OpenAQ. OpenAQ aggregates data from local monitoring stations and makes it publicly available. Measurements reflect the conditions at the time of sampling. The three valid measurements were combined to produce the overall rating. The assessment combines the available observations to assign the Good category. The PM10 concentration is expressed in micrograms per cubic meter. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Voitsberg in Styria, Austria, contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). All values come from a single monitoring site on Mühlgasse, giving a total of eight data rows. Across the whole set three rows were updated within the last three days, while the remaining five rows are classified as old. The most recent timestamps are from 2026‑02‑10 20:00 UTC for NO₂, O₃ and PM10; the NO reading dates back to 2024‑03‑11 12:00 UTC and the PM2.5 entry to 2025‑12‑31 00:00 UTC.

For the recent pollutants the observed ranges are modest. NO₂ values span from 13.55 µg/m³ up to 53 µg/m³, with a median of about 33.28 µg/m³, indicating that most recent measurements sit near the middle of that interval. Ozone varies between 18.0 µg/m³ and 21.45 µg/m³, median 19.72 µg/m³, showing a narrow spread around the typical level. PM10 ranges from 28.02 µg/m³ to 38 µg/m³, median 33.01 µg/m³, again a relatively tight distribution. In contrast, NO is represented by a single value of 6.82 µg/m³ from the older 2024 record, and PM2.5 shows only a placeholder value of –1 µg/m³ from the 2025 entry, suggesting limited or missing recent data for these two components.

Overall the coverage is concentrated on one station, and while the newest data provide a clear picture for NO₂, O₃ and PM10, the older timestamps for NO and the lack of current PM2.5 measurements mean that the dataset does not capture the full temporal variability of air quality across the city. Users should keep in mind that conditions can differ by location and time, especially for the pollutants with sparse or outdated records.
