Castrop-Rauxel's air quality reflects the Rhine-Ruhr conurbation's coal mining heartland, with the legacy of coal extraction and chemical manufacturing combined with vehicle traffic on the A42 motorway generating elevated PM2.5 and industrial background pollution. The flat Ruhr basin provides some wind dispersal, while the surrounding industrial density of the Herne-Castrop-Rauxel corridor maintains consistently above-average European pollution levels throughout the year.
