Air quality today

The air quality in Sevlievo is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 17.98 µg/m³ and a PM10 value of 19.88 µg/m³, based on 17 valid observations collected via OpenAQ.

These figures reflect the present conditions without implying any trend or cause. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Sevlievo air‑quality feed contains data for ten measured parameters – carbon monoxide (CO), humidity, nitrogen dioxide (NO₂), four size fractions of particulate matter (PM1, PM2.5, PM4 and PM10), atmospheric pressure, sulfur dioxide (SO₂) and temperature. The dataset is built from five monitoring stations that together contributed 57 recent rows of observations.

All pollutants have at least one reading updated within the last three days, with the most recent timestamps ranging from 2026‑02‑10 22:28 UTC for CO, PM1, PM10, temperature and pressure to 2026‑02‑10 22:29 UTC for humidity, PM2.5, PM4 and pressure. The median values show a relatively narrow central tendency for most components: PM1 sits at 14.08 µg/m³, PM10 at 19.88 µg/m³, PM2.5 at 17.98 µg/m³ and PM4 at 19.85 µg/m³; humidity averages 85.18 % and temperature 1.2 °C. The spread between minimum and maximum observations is modest for the particulate fractions (PM1 ranges from 6.11 to 42.94 µg/m³, PM10 from 6.46 to 45.47 µg/m³) but larger for CO, which varies from 164.21 to 447.92 µg/m³ across the limited two‑row sample.

Coverage is uneven: while particulate matter and humidity have five recent rows each, CO is represented by only a single recent entry, and there are no current values for NO₂ or SO₂ in this snapshot. Moreover, the quality‑flag breakdown shows that 22 of the 57 rows are classified as “unknown”, indicating that a substantial portion of the data lacks full verification. Consequently, while the available figures give a snapshot of typical conditions at specific sites such as Svoboda Square and the city centre, actual air quality can differ across other neighbourhoods and times not captured by the most recent measurements.

Data notes

The dataset for Sevlievo includes 17 valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑10 at 22:29 UTC. These figures represent a snapshot of ambient conditions captured by the monitoring network; actual air quality can differ across neighborhoods and change throughout the day, so local variations may not be reflected in this summary.
