Seraing's air quality faces significant challenges as the former heart of the Liège Meuse industrial valley, with the ArcelorMittal Liège steel operations legacy and the surrounding chemical and manufacturing industry generating elevated PM2.5 and industrial background alongside vehicle traffic on the E42 motorway. The Meuse valley's topographic enclosure concentrates emissions under frequent inversions, making Seraing one of Belgium's more persistently challenging post-industrial air quality environments throughout the year.

Are air quality levels in Seraing 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.
