Air quality today
The air quality in Lopik today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 6.152 and a PM10 reference value of 6.99, based on six valid observations collected via OpenAQ.
Overall conditions meet the criteria for the Good category according to the available data. 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 Lopik air‑quality record draws on a single monitoring site that supplies seven data rows, one for each of the measured pollutants — carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). All values are reported in micrograms per cubic metre.
For five of the seven pollutants the most recent observation was recorded on 2026‑02‑10 at 21:00 UTC, meaning the data are fresh within the last week. The exception is CO, whose latest entry dates back to 2020‑03‑02 11:00 UTC and is flagged as “old data”, so its current level in Lopik cannot be inferred from this set. The numeric readings themselves show very little variation because each pollutant has only a single reported value: NO sits at 0.22 µg/m³, NO₂ at 12.53 µg/m³, O₃ at 31.01 µg/m³, PM₁₀ at 6.99 µg/m³, PM₂.5 at 6.152 µg/m³ and SO₂ at 0.08 µg/m³. Because there is just one measurement per pollutant, statistical summaries such as minimum, median or maximum are all identical to that single figure.
The dataset therefore offers a snapshot rather than a range of conditions, with most pollutants represented by recent but singular values and CO standing out as outdated. Users should keep in mind that air quality can differ across neighbourhoods and over time, and the limited temporal depth here means the picture for Lopik is necessarily coarse.

Data notes
The data shown are based on six valid measurements and were refreshed recently, having been updated within three days (last update: 2026‑02‑10 21:00 UTC). This snapshot reflects conditions at the time of collection; air quality can vary across different neighbourhoods and moments throughout Lopik, so values may not represent every location or instant in the city.
