Air quality today

The air quality in Baia Mare is currently classified as Good. The primary pollutant measured today is PM10, with a reported concentration of 15.26 µg/m³ based on the available data set.

A total of 22 valid measurements were recorded for this assessment, and the PM10 value aligns with the reference figure provided. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Baia Mare air‑quality record draws on six monitoring rows that together report five pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and sulfur dioxide (SO₂). All six rows have been refreshed within the past week, with the most recent update logged on 2026‑02‑10 at 19:00 UTC for each pollutant.

Across the dataset CO shows a very wide spread, ranging from a low of –1 000 µg/m³ (the sensor’s reporting floor) up to 2 031.65 µg/m³, with a median value of about 68.23 µg/m³ and a 90th‑percentile near 691 µg/m³. NO₂ values are more tightly clustered between roughly 7 µg/m³ and 58.9 µg/m³, centering on a median of 21.01 µg/m³; the interdecile range runs from about 13 µg/m³ to 45 µg/m³. O₃ concentrations vary dramatically, from a minimum of 49.49 µg/m³ to a peak of 605.52 µg/m³, with the median sitting at 63.84 µg/m³ and the 90th‑percentile reaching 353.80 µg/m³. PM₁₀ measurements are comparatively modest, spanning 2 µg/m³ to 15.26 µg/m³, a median of 9.52 µg/m³ and a 90th‑percentile around 12.15 µg/m³. SO₂ is the least variable, recorded between –1 µg/m³ and 7.57 µg/m³, with a median of 1.56 µg/m³ and a maximum that also serves as its 90th‑percentile.

The data set therefore offers recent, multi‑pollutant coverage but reveals uneven distributions: CO and O₃ display the broadest ranges, while SO₂ remains tightly bounded. All pollutants are represented by the same six rows, yet the extreme values for some gases suggest that conditions can differ markedly across locations and moments within Baia Mare.
