Most's air quality faces serious challenges from the North Bohemian lignite mining and chemical industry corridor, with the surrounding Litvínov and Záluží chemical complexes — including the Unipetrol Chempark — generating elevated industrial SO₂, benzene, and PM2.5 alongside the lignite open-cast mining operations in one of the Czech Republic's most industrially intensive regions. The flat North Bohemian basin and Ore Mountain barrier create the primary topographic influences throughout the year.

Is air quality bad in Most right now?
On 9 August 2026, overall air quality in Most is fair. NO2 is the main pollutant at 27.6/100. Pollution peaks around 3:00 PM (O3: 46.7/100).
Will air quality be worse tomorrow in Most?

When is air pollution at its worst in Most?
Air quality dips in Most mostly track local tree and grass allergens peaks and periods of the neighbouring Litvínov and Záluží chemical complexes — including the Unipetrol Chempark —; the clearest air tends to follow a change in wind direction or rainfall here.
Are air quality levels in Most based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
