Air quality today

The air quality in Dunaújváros is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 22.0 µg/m³ and a PM10 level of 17.0 µg/m³, based on five valid observations collected via OpenAQ.

These values reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Dunaújváros contains measurements for six key pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). All values come from a total of twelve data rows collected at two monitoring stations, giving a modest spatial coverage across the city.

Each pollutant has a recent update timestamp of 2026‑02‑10 20:00 UTC, meaning the newest observations are all within the last three days. The recorded ranges show that CO values sit tightly between 543 and 552 µg/m³ with a median of about 548 µg/m³, while NO₂ varies from 12.2 to 16.6 µg/m³ (median ≈ 14.4). Ozone spans 28.2–36.0 µg/m³ (median ≈ 32.1), and the particulate matter series are broader: PM₁₀ ranges 5.8–17.0 µg/m³ (median ≈ 11.4) and PM₂.₅ spans 6.6–22.0 µg/m³ (median ≈ 14.3). Sulfur dioxide is the lowest‑level pollutant, recorded between 1.97 and 2.5 µg/m³ (median ≈ 2.24).

The data illustrate a fairly consistent reporting cadence across all six pollutants, with no missing or unknown timestamps among the twelve rows. However, because only two stations contribute, the measurements represent limited points in the urban area; conditions can differ between neighborhoods and at times not captured by these snapshots. The narrow spread for CO and SO₂ contrasts with the wider variability seen in PM₁₀ and PM₂.₅, indicating that particulate concentrations fluctuate more across the monitored locations.

Data notes

The data shown for Dunaújváros is based on five valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T20:00:00+00:00 (updated within 3 days). These readings provide a snapshot of current conditions, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
