What the data includes

The air‑quality data for Buzău currently comes from a single monitoring site (BZ‑1) that provides fourteen recent rows of measurements across five pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀) and sulfur dioxide (SO₂). All the values were last refreshed on 2026‑02‑10 at 19:00 UTC, so the dataset is uniformly recent and falls within the “updated within 7 days” freshness bucket.

Across the pollutants the observed ranges are quite different. CO shows the widest spread, with a minimum of about 92 µg/m³, a median near 203 µg/m³ and a maximum of 314 µg/m³; the 10th‑percentile is roughly 114 µg/m³ while the 90th‑percentile reaches almost 292 µg/m³. NO₂ values range from 17.6 to 63.1 µg/m³, with a median of 28.3 µg/m³ and the inter‑decile band (10th‑90th percentile) stretching from about 20 to 56 µg/m³. O₃ varies between 20.9 and 169.9 µg/m³, median 51.7 µg/m³, with most readings (10th‑90th percentiles) falling between 27 and 146 µg/m³. PM₁₀ is the least variable, spanning 9.8 to 26.6 µg/m³, median 15.8 µg/m³, and an inter‑decile range of roughly 11 to 24 µg/m³. SO₂ stays low throughout, from 3.90 to 6.15 µg/m³, median 4.17 µg/m³, with the central 80 % of values between about 4.0 and 5.8 µg/m³.

Because the data originates from a single station, spatial coverage across Buzău is limited; conditions can differ in other neighborhoods or at different times of day. Nevertheless, the dataset offers a recent snapshot for each pollutant, showing that CO and O₃ exhibit the greatest variability while PM₁₀ and SO₂ remain comparatively stable within the recorded period.
