Air quality today

The air quality in Most today is classified as Moderate. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 14.4 and a PM10 reference value of 14.3, based on four valid observations recorded by OpenAQ.

What the data includes

The dataset for Most includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM₁₀) and particulate matter 2.5 µm or smaller (PM₂.₅). All values come from a single monitoring station, so the coverage is limited to one location within the city. The freshest data are from 2026‑02‑10 14:00 UTC for NO₂, O₃, PM₁₀ and PM₂.₅, while the NO measurement dates back to 2024‑03‑11 10:00 UTC, making it the oldest entry in the set.

Across the pollutants the reported figures are identical to their median values, indicating no observed variability at this station during the recorded periods. NO is measured at 1.7 µg/m³, NO₂ at 11.5 µg/m³, O₃ at 48.9 µg/m³, PM₁₀ at 14.3 µg/m³ and PM₂.₅ at 14.4 µg/m³; each pollutant’s minimum, median and maximum are the same, so the spread (p10‑p90) is effectively zero. This uniformity suggests that only a single snapshot per pollutant is currently available rather than a range of observations.

Because the dataset consists of just one recent row for four pollutants and an older row for NO, it provides a very narrow picture of air quality in Most. Conditions can differ across neighborhoods and over time, so while these numbers give a baseline for the specific monitoring point, they do not capture city‑wide variations or short‑term changes.
