Air quality today
The air quality in Pleven today falls into the Good category. According to the latest available data, the dominant pollutant is PM10, measured at 23.11 µg/m³. The reference value for PM10 is also 23.11 µg/m³, matching the reported concentration. This figure is derived from three valid observations contributed by separate monitoring sites and aggregated through the OpenAQ platform. No PM2.5 measurement is reported for the current period.
All figures are presented as reported by OpenAQ without additional interpretation, and the dataset is updated as new measurements become available. The information reflects a snapshot of conditions at the time of sampling and does not imply any trend. 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 Pleven, Bulgaria pulls measurements from a single monitoring site – AMS Patriarch Evtimiy – and contains five rows of data, each representing one of the five pollutants tracked: carbon monoxide (CO), nitrogen monoxide (NO), nitrogen dioxide (NO2), particulate matter 10 µm (PM10) and sulfur dioxide (SO2). In total, the city’s air‑quality record consists of five observations, all recorded at the same station, so the spatial coverage is limited to that location.
Freshness varies across the pollutants. The most recent timestamps are from 2026‑02‑10 19:00 UTC for CO, PM10 and SO2, and from 2026‑01‑24 11:00 UTC for NO2, placing four of the five measurements within the last 30 days. The NO reading is older, last updated on 2024‑03‑11 11:00 UTC, and together the five rows break down into three recent entries and two older ones, indicating that the majority of the data is current but a single pollutant lags behind. Because only one station contributes, the dataset does not capture city‑wide variation and reflects conditions at a specific point in Pleven.
Each pollutant is represented by a single value with no observed spread: CO registers at 1890.0 µg/m³, NO at 10.95 µg/m³, NO2 at 9.48 µg/m³, PM10 at 23.11 µg/m³ and SO2 at 6.99 µg/m³. The minimum, median and maximum are identical for every pollutant, so the data set provides a snapshot rather than a range of measurements. This limited temporal depth means that while the figures give a clear point‑in‑time picture, they do not reveal fluctuations that might occur at other times or locations across the city.
