Air quality today

The air quality in Focșani is classified as Good today. The primary pollutant identified is PM10, the coarser particulate matter measured in the city’s monitoring network.

Five valid measurements were recorded, and the reported PM10 concentration aligns with a reference value of 9.0 µg/m³. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Focșani is built from two monitoring stations that together provide data on five key pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO2). All of the most recent measurements were uploaded on 2026‑02‑10 at 19:00 UTC, so the dataset reflects conditions that are less than a week old for every pollutant.

For NO2 the two stations report values ranging from 12.54 to 16.06 µg/m³, with a median of about 14.30 µg/m³ and the central 80 % of observations falling between roughly 12.89 and 15.71 µg/m³. Ozone shows a tighter spread: minimum 58.64, maximum 61.26 µg/m³, median 59.95 µg/m³ and an 80 % interval from 58.90 to 60.99 µg/m³. CO, PM10 and SO2 each have a single reported value – 58.48 µg/m³ for CO, 9.0 µg/m³ for PM10 and 6.77 µg/m³ for SO2 – because only one station currently provides data for those pollutants.

The coverage is uneven: while NO2 and O3 benefit from two reporting stations, the other three compounds rely on a single source, limiting spatial detail for them. Nevertheless, all rows are recent; none fall into older or unknown freshness categories. Because the dataset comprises just two stations, it captures only part of the city’s air‑quality picture, and conditions can differ across neighborhoods and over time despite the overall recency of the data.

Data notes

The data shown for Focșani is based on five valid measurements and was refreshed within the past three days, with the most recent update recorded at 2026‑02‑10T19:00:00+00:00. This snapshot reflects conditions at specific monitoring points and times; air quality can differ across neighborhoods and vary throughout the day, so values may not represent every location or moment in the city.
