Air quality today

The air quality in Deva is classified as Good today. The primary pollutant identified is PM10, with a measured reference value of 16.66 micrograms per cubic metre based on seven valid observations.

Data are shown via OpenAQ and reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

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 Deva contains observations from four monitoring stations, amounting to sixteen individual rows of data. For every station the OpenAQ feed supplies recent measurements of five key pollutants: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or smaller (PM10) and sulfur dioxide (SO₂). All of the latest values were recorded at the same moment – 2026‑02‑10 19:00 UTC – which means the information is current within the last seven days for each pollutant.

The numeric spread differs noticeably across the compounds. NO₂ values range from a low of about 0.65 µg/m³ to a high of 26.49 µg/m³, with a median near 15.39 µg/m³ and the central 80 % of observations falling between roughly 4.87 and 23.36 µg/m³. O₃ shows a broader interval, from –1.0 to just over 100.97 µg/m³; its median is 57.91 µg/m³ and the 10th‑90th percentile band stretches from about 12.65 to 92.07 µg/m³. SO₂ measurements sit between 3.61 and 16.23 µg/m³, centering on a median of 8.44 µg/m³, while PM10 values are tighter, ranging from 10.14 to 16.66 µg/m³ with a median of 13.40 µg/m³. CO is reported as –1000.0 µg/m³ for all rows, indicating that the sensor data for this pollutant is not available or invalid at these stations.

Because the dataset includes only four stations, spatial coverage across Deva is limited; conditions can vary in neighborhoods that are not directly represented by a monitoring site. The freshness of the timestamps is uniform and recent, yet the absence of valid CO readings and the relatively small number of rows mean the picture of air quality is incomplete. Users should keep in mind that these figures reflect the specific locations and times captured by the available sensors rather than a city‑wide average.

Data notes

The data shown for Deva is based on seven valid measurements and was refreshed within three days, with the latest update recorded at 2026‑02‑10 19:00 UTC. These figures provide a current snapshot of citywide air quality but may not reflect conditions at every neighbourhood or moment, as concentrations can change across locations and times throughout the day.
