Air quality today

The air quality in Calafat today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 17.70676 µg/m³ and a PM10 level of 17.44367 µg/m³, based on six valid observations.

Data are shown via OpenAQ and reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Calafat air‑quality record draws on a single monitoring station, so all reported numbers come from one location. Five pollutants are represented: carbon monoxide (CO), nitrogen dioxide (NO2), particulate matter 10 µm and smaller (PM10), fine particulate matter 2.5 µm and smaller (PM2.5), and sulphur dioxide (SO2). The most recent data for CO, NO2, PM10 and PM2.5 were all logged on 2026‑02‑10 at 19:00 UTC, while the SO2 entry dates back to 2024‑10‑21 at 09:00 UTC, indicating that sulphur dioxide information is considerably older than the other measurements.

Across the four newer pollutants the values are identical for their minimum, median and maximum, showing no observed variation in this snapshot. CO registers a concentration of 491.91 µg/m³, NO2 measures 16.93814 µg/m³, PM10 records 17.44367 µg/m³ and PM2.5 shows 17.70676 µg/m³; each of these figures is the sole reading available for its respective pollutant. In contrast, the SO2 value is listed as –1.0 µg/m³, a placeholder that signals missing or invalid data rather than an actual measurement.

Because only one row of recent data exists for most pollutants, the dataset does not capture spatial or temporal variability within Calafat. The freshness of the CO, NO2, PM10 and PM2.5 readings is good – all updated within the last seven days – but the sulphur dioxide record is outdated by more than a year. Consequently, while the current snapshot provides concrete numbers for four key pollutants, it offers limited insight into how air quality may differ across neighborhoods or change over time in this city.

Data notes

The current dataset for Calafat includes six valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 19:00 UTC; it is therefore marked as Updated within 3 days. This snapshot reflects conditions captured at that time, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be fully represented in these figures.
