Air quality today

The air quality in Campagne-lès-Boulonnais is currently classified as Good. The primary pollutant identified is PM10, with a reported reference value of 12.8 µg/m³. This assessment is based on four valid measurements that satisfy the data quality criteria. No additional pollutants were reported as dominant in the latest dataset. The PM10 concentration of 12.8 µg/m³ falls within the range associated with the Good category according to the assessment criteria. All four measurements were recorded within the same monitoring interval, providing a consistent snapshot of ambient conditions. The dataset does not indicate elevated levels of finer particles such as PM2.5 for this period.

The information is displayed via OpenAQ, which aggregates the available monitoring data for the area. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Campagne‑les‑Boulonnais in the Hauts‑de‑France region comes from a single OpenAQ monitoring site that contributes five data rows. The dataset includes measurements for nitrogen dioxide, ozone, particulate matter ≤ 10 µm, particulate matter ≤ 2.5 µm, and sulfur dioxide. The most recent NO2 value is 2.4 µg/m³ recorded at Campagne les B. on 2026-02-10 15:00 UTC. Ozone is reported at 40.6 µg/m³ from 2026-01-30 10:00 UTC. PM10 stands at 12.8 µg/m³ as of 2026-02-09 03:00 UTC. PM2.5 shows a concentration of 7.7 µg/m³, but that reading dates back to 2025-01-29 14:00 UTC. Sulfur dioxide is measured at 0.2 µg/m³ from 2026-01-28 09:00 UTC.

All five pollutants have a single reported figure, so the internal range for each is zero – the minimum, median and maximum values are identical. Four of the five rows (NO2, O3, PM10, SO2) were updated within the last 30 days, while the PM2.5 entry is classified as old, indicating a gap of more than a year for that component. Because the data originates from only one station, spatial coverage across the city is limited; conditions in other neighbourhoods may differ from the values shown here. The overall freshness profile is therefore mixed: recent for most pollutants but lacking recent PM2.5 information.

In terms of data freshness categories, none of the five entries are from today, the past three days, or the past week. Four entries fall into the ‘updated within 30 days’ bucket, reflecting recent monitoring for NO2, O3, PM10 and SO2. The remaining entry, the PM2.5 measurement, is classified as old, meaning it is older than 30 days. No rows are marked as unknown, so each pollutant has a defined timestamp, but the single‑station setup means the temporal picture is limited to these specific moments.
