Air quality today
The air quality in Chișinău today falls into the Moderate category. The primary pollutant measured is PM2.5, with a reported concentration of 17.81 µg/m³ based on five valid observations from OpenAQ data.
Overall conditions reflect a moderate level of fine particulate matter without additional pollutants reported. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Chișinău contains six measured variables – fine particles (PM2.5), coarse particles (PM1 and PM10), relative humidity, temperature and particle count (UM003). All values come from two monitoring stations that together provide seven rows of data. For most pollutants the most recent reading is from 2026‑02‑10 22:00 UTC, which means the information is fresh – updated within the last week. The exception is PM10, whose latest entry dates back to 2025‑01‑13 23:00 UTC, so that particular series is considerably older than the others.
Across the recent records the observed concentrations show a modest spread. PM2.5 ranges from 13.0 to 17.8 µg/m³ with a median of about 15.4 µg/m³, while PM1 is recorded at a single value of 11.19 µg/m³. The older PM10 reading stands at 50.39 µg/m³, providing only one data point for that pollutant. Relative humidity and temperature are also reported as single values – 53.08 % and 3.94 °C respectively – reflecting the limited temporal depth of the current dataset. Particle count (UM003) is measured at 1 675.4 particles per cm³, again from the most recent timestamp.
Because only two stations contribute data, spatial coverage within the city is limited; conditions can differ in other neighborhoods that are not represented here. The overall freshness is good for five of the six variables, but the older PM10 record highlights an uneven update frequency across pollutants. Users should keep in mind that these snapshots capture a narrow moment in time and may not reflect broader daily or seasonal variations throughout Chișinău.
