Air quality today

The air quality in Iași is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 11.58 µg/m³ and a PM10 level of 15.20 µg/m³, based on fourteen valid observations.

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

What the data includes

The dataset for Iaşi contains measurements for six common air‑quality pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10), particulate matter 2.5 µm or less (PM₂.5) and sulphur dioxide (SO₂). In total 25 data rows have been collected from six monitoring stations across the city, giving a modest spatial coverage that can capture differences between neighbourhoods but does not provide exhaustive city‑wide detail.

The most recent values are available for NO₂, PM10, PM₂.5 and SO₂, all updated on 2026‑02‑10 19:00 UTC, showing that these four pollutants have fresh data within the last week. Their median concentrations are 17.60 µg/m³ for NO₂, 15.20 µg/m³ for PM10, 11.58 µg/m³ for PM₂.5 and 6.05 µg/m³ for SO₂, with observed ranges spanning from about 10 to 76 µg/m³ for NO₂, 9 to 78 µg/m³ for PM10, 6 to 64 µg/m³ for PM₂.5 and a narrow 1 to 6 µg/m³ window for SO₂. This indicates that the newer data capture both low‑level background conditions and higher spikes within the same monitoring period.

In contrast, ozone and carbon monoxide are represented by single historic records – O₃ from 2023‑05‑29 10:00 UTC (value 97.41 µg/m³) and CO from 2025‑11‑15 08:00 UTC (value ‑1000.0 µg/m³, which appears to be an erroneous placeholder). Because these two pollutants lack recent observations, the dataset provides limited insight into their current behaviour in Iaşi. Overall, while the city’s air‑quality picture includes up‑to‑date information for four key pollutants, the sparse and outdated coverage for O₃ and CO means that conditions can still vary by location and time beyond what is captured here.

Data notes

The data shown reflects 14 valid measurements and is Updated within 3 days, with the latest reading recorded at 2026‑02‑10T19:00:00+00:00. These values provide a current snapshot of air quality across Iași, but conditions can differ by neighbourhood and time of day, so the figures may not represent every location or moment within the city.
