Air quality today

The air quality today in the Municipality of Peristeri is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles).

Measurements from eight valid monitoring points show a PM2.5 concentration of 27.78 µg/m³ and a PM10 level of 21.0 µg/m³. Data is 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 the Municipality of Peristeri in Attica contains measurements for nine pollutants – NO, NO₂, O₃, PM1, PM2.5, relative humidity, temperature, and particle count (UM003). The information comes from three monitoring stations that together provide 14 recent rows of data. Most of the values are very fresh: the latest updates for PM‑related measurements, humidity, temperature and UM003 were recorded on 2026‑02‑10 at 21:00 UTC, while NO₂ and O₃ were last reported on 2026‑02‑10 at 19:00 UTC. The only older entry is the single NO reading from 2024‑03‑11, which means that for this gas the dataset relies on a measurement that is almost two years out of date.

Across the recent records the concentrations show a modest spread. PM1 values range from about 5.5 to 17 µg/m³ with a median near 11 µg/m³, while PM2.5 varies between roughly 9 and 28 µg/m³ and has a median close to 18 µg/m³, indicating that fine particles are generally higher than the coarser fraction. Relative humidity stays within a narrow band of 40 % to 51 %, with a typical value around 46 %; temperature fluctuates between about 14.6 °C and 20.5 °C, centering near 17.5 °C. The particle count (UM003) spans from roughly 560 to 986 particles per cubic centimetre, medianing at about 774, which reflects a fairly consistent aerosol load across the monitoring period.

Because the dataset includes only three stations, spatial coverage is limited and conditions can differ in other parts of Peristeri. Most pollutants have up‑to‑date readings from the last few days, but the single NO measurement is outdated, so any interpretation of nitrogen monoxide levels should be treated with caution. Overall, the data give a recent snapshot of particulate matter, humidity, temperature and ozone, while older or missing entries for some gases highlight gaps that users should keep in mind when assessing city‑wide air quality.
