Krefeld's air quality reflects its position in the Lower Rhine conurbation, with vehicle traffic on the A57 and the surrounding textile and chemical manufacturing legacy of the former Prussian silk city contributing elevated NO₂ and PM2.5. The flat Rhine valley plain provides reasonable wind dispersal on most days, while the surrounding Rhine-Ruhr industrial complex elevates background pollution levels above typical western European urban averages, and Krefeld's chemical industry legacy maintains localised elevated baseline readings.
