Air quality today

The air quality in Montcada i Reixac is classified as Good today. The main pollutant identified is PM10, with a reference value of 15.0 µg/m³ based on seven valid measurements.

Measurements show that the current PM10 concentration aligns with the reference level of 15.0 µg/m³, and no other pollutants are highlighted in the assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Montcada i Reixac air‑quality dataset contains measurements for seven pollutants: carbon monoxide (CO), nitrogen oxides (NO, NO₂, NOX), ozone (O₃), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO₂). Data are drawn from two monitoring stations, giving a total of ten recent rows. Freshness varies: seven rows have been updated within the last week, while three rows are older than seven days; none are from today or the past three days.

Across the pollutants the recorded values show a fairly narrow spread for most substances. CO ranges from 200 µg/m³ to 500 µg/m³ with a median of 350 µg/m³, indicating that recent measurements cluster around the middle of this interval (the 10th percentile is 230 µg/m³ and the 90th percentile 470 µg/m³). NO₂ values sit between 23 µg/m³ and 42 µg/m³, median 32.5 µg/m³; again the spread is modest (24.9–40.1 µg/m³ for the central 80%). In contrast, SO₂, NO, NOX, O₃ and PM10 each have a single reported value—3 µg/m³, 4 µg/m³, 28 µg/m³, 21 µg/m³ and 15 µg/m³ respectively—so no range can be derived for those gases from the current rows.

The dataset therefore offers a fairly complete picture of CO and NO₂ variability but provides limited insight into the other five pollutants because only one measurement per pollutant is available. With most rows refreshed within the past week, the information reflects recent conditions, yet the three older entries remind users that air quality can change across locations and times not captured by this snapshot.
