Air quality today
The air quality in Hoogvliet is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 9.5 and a PM10 reference value of 14.0, based on five valid observations collected through OpenAQ.
These figures reflect the present conditions without implying any trend or cause. 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 Hoogvliet air‑quality dataset contains six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). All values come from a single monitoring location, Hoogvliet‑Leemkuil, so the dataset represents one row per pollutant, giving a total of six rows of data for the city.
Freshness varies across the pollutants. The most recent updates were recorded on 2026‑02‑10 at 21:00 UTC for NO₂, O₃, PM₁₀, PM₂.₅ and SO₂, meaning those five measurements are all less than seven days old. In contrast, the NO reading is dated 2024‑03‑25 at 22:00 UTC and is flagged as “old data,” so it does not reflect current conditions. Because only one station contributes data, there is no spatial spread within Hoogvliet; any local variations in air quality are not captured by this dataset.
The numeric values show no internal variation – each pollutant’s minimum, median and maximum are identical. NO₂ registers at 33.9 µg/m³, O₃ at 24.8 µg/m³, PM₁₀ at 14.0 µg/m³, PM₂.₅ at 9.5 µg/m³ and SO₂ at 1.0 µg/m³, while the NO entry is recorded as –999.0 µg/m³, indicating missing or invalid data. Consequently, the dataset provides a single snapshot per pollutant rather than a range of observed values. Users should keep in mind that conditions can differ across neighborhoods and over time, and the current figures represent only the latest available measurement from this one site.

Data notes
The data shown for Hoogvliet is based on five valid measurements and has been refreshed recently, with the latest update recorded on 2026‑02‑10 at 21:00 UTC (updated within 3 days). While this snapshot provides a reliable overview of current conditions, air quality can differ across neighbourhoods and change throughout the day, so local variations may not be fully captured in these figures.
