Air quality today

The air quality in Clairton, Pennsylvania is rated as Moderate today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 9.8 µg/m³ based on one valid observation reported through OpenAQ.

Data for this assessment are limited to the single available reading and do not include PM10 values. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Clairton includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), fine particulate matter (PM2.5), the legacy PM2.5 metric (PM25‑OLD) and sulfur dioxide (SO2). Data come from three monitoring stations, giving a total of thirteen rows across all pollutants. The most recent observation in the set is the PM2.5 value recorded on 2026-02-11 00:00 UTC; every other pollutant’s latest reading dates back to 2022-02-09 00:00 UTC, so five of the six metrics are based on data that are more than four years old.

PM2.5 values range from a low of 9.8 µg/m³ to a high of 15.53 µg/m³, with a median near 14.95 µg/m³ and the inter‑decile spread (10th–90th percentile) between roughly 10.83 and 15.41 µg/m³. The older PM25‑OLD measurements sit in a tighter band from about 14.95 to 15.53 ugm3, reflecting little variation in that legacy metric. CO concentrations span 0.1635 to 0.1873 ppm (median ≈ 0.1754 ppm), while NO2 runs from 0.00719 to 0.00909 ppm (median ≈ 0.00814 ppm). Ozone is recorded between 0.0268 and 0.0295 ppm (median ≈ 0.0281 ppm) and SO2 ranges from 0.000416 to 0.000647 ppm (median ≈ 0.000531 ppm).

Because five of the six pollutants rely on data that are several years old, the snapshot does not capture current day‑to‑day fluctuations in Clairton’s air quality. The limited number of stations also means spatial coverage is modest; conditions can differ across neighborhoods and times even though the dataset provides a baseline view of each pollutant’s recent historical range.
