Air quality today
The air quality in Neath Port Talbot today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 2.0 µg/m³ and a PM10 reference value of 7.0 µg/m³, based on five valid observations recorded by OpenAQ.
Overall conditions meet the Good category criteria according to the latest data available for this location. 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 dataset for Neath Port Talbot contains a single monitoring location – Port Talbot Margam (UKA00501) – and therefore one row of measurements for each pollutant. All six key pollutants tracked by OpenAQ are present: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). The most recent values were recorded on 2026‑02‑10, with CO logged at 19:00 UTC and the remaining five pollutants at 20:00 UTC, meaning the data are all fresh within the last seven days.
Across the six substances the reported figures are identical for minimum, median and maximum, indicating that only one observation per pollutant is currently available. CO registers a concentration of 267.766 µg/m³, NO₂ 15.0 µg/m³, O₃ 62.0 µg/m³, PM₁₀ 7.0 µg/m³, PM₂.₅ 2.0 µg/m³ and SO₂ 1.0 µg/m³. Because each pollutant has a single data point, the inter‑quartile range (10th to 90th percentile) collapses to that same value, so no spread can be described from this snapshot.
The limited coverage – one station providing one recent reading per pollutant – means the dataset does not capture spatial variation across Neath Port Talbot or temporal changes beyond the recorded moment. Consequently, while the figures give a current picture of air quality at the Margam site, conditions elsewhere in the city may differ and later updates could show new values. Users should keep in mind that this snapshot reflects only one location and time point within the broader urban environment.

Data notes
The data shown are based on five valid measurements and have been refreshed recently, being updated within three days (last update 2026‑02‑10T20:00:00+00:00). This snapshot reflects conditions at the time of collection but air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in Neath Port Talbot.
