Air quality today

The air quality in Notre‑Dame‑de‑Bliquetuit is currently classified as Moderate. The primary pollutant identified for today is PM2.5 (fine particles).

Measurements from five valid samples show a PM2.5 concentration of 10.3 µg/m³ and a PM10 level of 12.4 µg/m³. These values are presented through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality dataset for Notre‑Dame‑de‑Bliquetuit contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulphur dioxide (SO2). All values come from a single monitoring location, Maison Parc Brotonne, so the station count is one row per pollutant.

The most recent measurements are from 2026‑02‑10 17:00 UTC for NO2, O3 and SO2, and from 2026‑02‑09 03:00 UTC for PM2.5 and PM10, indicating that four of the six pollutants have data updated within the last three days. The NO reading is older, dated 2024‑03‑11 09:00 UTC, which means its timestamp is nearly two years behind the others.

Across the recent data the observed ranges are modest. NO2 varies between 4.9 and 11.8 µg/m³ with a median of about 8.35 µg/m³; O3 spans 55.7 to 64.8 µg/m³, median roughly 60.25 µg/m³; PM2.5 runs from 10.3 to 17.7 µg/m³, median 14.0 µg/m³; SO2 is tightly clustered between 1.9 and 2.1 µg/m³, median 2.0 µg/m³; PM10 shows a single reported value of 12.4 µg/m³; NO is recorded at a constant 10.1 µg/m³. The spread (difference between minimum and maximum) is smallest for SO2 and largest for NO2, highlighting uneven variability among pollutants.

Because the dataset relies on a single sensor site, spatial coverage across the city is limited, and the older NO measurement underscores that not all pollutants are refreshed equally often. Consequently, while recent values give a snapshot of current conditions at Maison Parc Brotonne, they may not fully represent variations elsewhere in Notre‑Dame‑de‑Bliquetuit or capture rapid changes between updates.
