Air quality today

The air quality in Brescia today is classified as Moderate. The primary pollutant measured is PM2.5. Data are based on 13 valid measurements. The observed PM2.5 concentration is 34.1 µg/m³, while PM10 stands at 52.8 µg/m³. PM2.5, a fine particulate matter, is identified as the dominant pollutant in the current dataset currently.

A total of 13 measurement points contributed to the current values. The reference value for PM2.5 is 34.1 µg/m³, matching the reported concentration, while the reference for PM10 is 52.8 µg/m³, also matching the reported level. These values are shown via OpenAQ.

What the data includes

The dataset for Brescia includes measurements of carbon monoxide, nitrogen dioxide, ozone, particulate matter ≤ 10 µm, particulate matter ≤ 2.5 µm, and sulfur dioxide. Four monitoring stations contribute a total of fourteen recent rows, all recorded within the past thirty days. The most recent reading in the set is from 2026‑02‑09 03:00 UTC (nitrogen dioxide and carbon monoxide at the Via Tartaglia site), while the other pollutants were last logged on 2026‑02‑08 19:00 UTC at either the Via Tartaglia or Villaggio Sereno locations. No observations are dated within the last seven days, but every entry is newer than a month, indicating a uniformly recent but not ultra‑current snapshot of air quality.

Coverage across pollutants is uneven. Nitrogen dioxide and PM2.5 each have four rows from four distinct stations, providing a broader spatial picture, whereas PM10 is represented by three rows from three stations. Carbon monoxide, ozone, and sulfur dioxide each appear in a single row from a single station, limiting the ability to compare across the city for those gases. The measured values show modest spreads: nitrogen dioxide ranges from about 22 µg/m³ to 38 µg/m³ with a median near 30 µg/m³; PM2.5 varies between roughly 8 µg/m³ and 34 µg/m³, median 31 µg/m³; PM10 sits between 40 µg/m³ and 53 µg/m³, median 44 µg/m³. Carbon monoxide is recorded at a single level of 735 µg/m³, ozone at 22 µg/m³, and sulfur dioxide at 4.5 µg/m³.

These figures illustrate that while Brescia’s air‑quality feed captures all six key pollutants, the depth of spatial sampling differs markedly among them, and the most recent data are up to a day old but none are from the immediate past week. Consequently, the snapshot reflects conditions across the city at a recent point in time, but local variations may exist that are not fully resolved for the less‑frequently sampled gases.

Data notes

The dataset for Brescia includes 13 valid measurements and is updated within 30 days. The latest data were recorded on 2026-02-09T03:00:00+00:00. These values represent a snapshot of ambient conditions and should be interpreted as such; air quality can vary by location and time within the city. Users are encouraged to consider this variability when reviewing the information.
