Air quality today
The air quality in Chrastava today is classified as Moderate. The primary pollutant identified is PM2.5. This assessment is based on two valid measurements. Data are shown via OpenAQ.
The reported concentrations are 16.8 µg/m³ for PM2.5 and 17.2 µg/m³ for PM10. These values correspond to the reference levels used for the assessment. PM2.5 denotes fine particles with diameters of 2.5 micrometers or less, while PM10 includes particles up to 10 micrometers. These measurements are part of the dataset compiled by OpenAQ for the region. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
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 current station data listed for this city is focused on particulate matter (PM). Only two pollutants are represented: PM10 and PM2.5, each reported from a single monitoring location identified as Horni Vitkov. The dataset contains one row per pollutant, and the most recent measurement for both was recorded on 2026-01-26 23:00 UTC, which falls within the last 30 days.
Both pollutants show a single observed value with no variation: PM10 is 17.2 µg/m³ and PM2.5 is 16.8 µg/m³, and the minimum, median, and maximum are identical for each. Because the data comes from only one site, there is no spread or range to describe across the city, and the figures cannot illustrate spatial differences or temporal trends. The freshness of the timestamps indicates the information is up‑to‑date, but the limited station coverage means the snapshot reflects conditions at Horni Vitkov alone and may not represent broader conditions throughout Chrastava.
