Viersen's air quality reflects the Lower Rhine conurbation in the Netherlands-Germany border region, with vehicle traffic on the A61 motorway and the surrounding textile and manufacturing legacy contributing local sources. The flat Lower Rhine plain provides reasonable dispersal on most days, while the surrounding Rhine-Ruhr industrial background elevates baseline PM2.5 and the consistent North Sea westerlies provide the primary ventilation pathway throughout the year.
