Air quality today
The air quality in Sept‑Îles is currently classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 3.1 µg/m³, based on two valid observations recorded by OpenAQ.
Overall conditions meet the criteria for the Good category with no 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 air‑quality record for Sept‑Îles currently draws from a single monitoring location that reports two pollutants: ozone (O₃) and fine particulate matter (PM₂.5). Both measurements were last refreshed on 2026‑02‑10 at 22:00 UTC, which places them well within the three‑day freshness window and makes the data among the most recent available for the city.
For ozone, the sensor reports a uniform value of 0.035 ppm across all recorded moments – the minimum, median, and maximum are identical, indicating no observed variation in this short snapshot. The PM₂.5 reading shows a similarly consistent figure of 3.1 µg/m³, again with no spread between its statistical extremes. Because only one row exists for each pollutant, there is no geographic diversity within the dataset; conditions elsewhere in Sept‑Îles may differ from what this single site captures.
Overall, the dataset offers complete coverage of the two listed pollutants but limited spatial depth, as it relies on a solitary monitoring station. The timestamps are current, yet the lack of multiple rows or older entries means there is no historical trend information to draw upon. Users should keep in mind that while these numbers reflect the latest readings at this specific location, air‑quality conditions can vary across different neighborhoods and times of day.
