Air quality today

The air quality in Onești is classified as Good today. The primary pollutant measured is PM10, with a reported concentration of 13.69 µg/m³ based on eleven valid observations collected via OpenAQ.

Overall conditions meet the Good category criteria, and the data reflect the current state without additional interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Onești air‑quality record includes five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀) and sulphur dioxide (SO₂). Data come from three monitoring stations that together contributed 16 recent rows of observations. Every pollutant has a most‑recent reading dated 2026‑02‑10 19:00 UTC, so the dataset is fresh, with all values updated within the past seven days.

Ozone shows the widest spread, ranging from a low of about 5 µg/m³ to a high of roughly 67 µg/m³, while the median value sits near 40 µg/m³ and the 10th‑percentile is just above 8 µg/m³. Nitrogen dioxide varies between roughly 4.7 and 24 µg/m³, with a median of 20 µg/m³ and a 90th‑percentile close to 23 µg/m³. PM₁₀ values are comparatively tight, staying between 13 and 27 µg/m³; the median is 13.7 µg/m³ and the inter‑decile range runs from about 13.2 to 24.3 µg/m³. Carbon monoxide measurements cluster in the high‑40s to low‑50s µg/m³, with a minimum of 40.9, a median of 46.4 and a maximum of 51.9 µg/m³. Sulphur dioxide is the most stable, ranging narrowly from 5.15 to 5.29 µg/m³, median 5.22 µg/m³.

Although the data are recent, coverage is limited: only three stations supply all five pollutants, and the total of 16 rows means that each pollutant is represented by just a handful of measurements (for example, CO and SO₂ each have two rows). Consequently, while the figures give a snapshot of current conditions in Onești, they do not capture fine‑grained spatial or temporal variations across the city.

Data notes

The data shown for Onești is based on 11 valid measurements and was refreshed recently, Updated within 3 days (last update: 2026‑02‑10T19:00:00+00:00). These readings provide a snapshot of current conditions but air quality can differ across neighbourhoods and change throughout the day, so local variations may not be captured in this summary.
