Air quality today

The air quality in Völklingen today is classified as Good. The primary pollutant identified is PM2.5 (fine particles).

Measurements from eight valid monitoring points show a PM2.5 reference value of 2.0 µg/m³ and a PM10 reference value of 3.32 µg/m³. These figures are presented through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Völklingen contains data on seven measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulphur dioxide (SO₂). These values come from two monitoring stations that together contribute ten individual rows of data. Freshness varies across the set: the most recent updates for PM10, PM2.5, SO₂, NO₂ and O₃ are all from 2026‑02‑10, recorded between 17:00 and 18:00 UTC, while CO is only available from a much older reading dated 2020‑08‑04 and NO from 2024‑03‑11. Consequently, half of the pollutants have measurements that are less than three days old, but the remaining three rely on data that is months or years stale.

Across the recent PM10 and PM2.5 records the observed range is narrow – PM10 values span 2.16 to 3.32 µg/m³ with a median of 2.74 µg/m³, and PM2.5 runs from 1.33 to 2.00 µg/m³ with a median of 1.67 µg/m³. SO₂ shows a similarly tight band between 1.09 and 1.81 µg/m³ (median ≈ 1.45 µg/m³). In contrast, the single‑point CO reading sits at 170 µg/m³, NO at 1.65 µg/m³, NO₂ at 9.44 µg/m³ and O₃ at 58.25 µg/m³, offering no insight into variability for those gases.

Overall the dataset provides a recent snapshot of particulate matter and ozone levels but is limited by sparse coverage for CO, NO and NO₂, where only one historic value exists per pollutant. Users should keep in mind that conditions can differ across neighborhoods and over time, especially given the mix of fresh and outdated observations.

Data notes

The data shown for Völklingen is based on eight valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T18:00:00+00:00 (updated within 3 days). This snapshot reflects conditions captured by the monitoring network at that time. Air quality can differ across neighborhoods and change throughout the day, so values may vary locally and temporally within the city.
