Chorzów's air quality faces serious challenges as part of the Upper Silesian Coal Basin, with the legacy of steel, chemical, and coke manufacturing combined with vehicle traffic on the surrounding road network generating elevated PM2.5, SO₂, and benzo[a]pyrene. The flat Silesian basin provides some wind dispersal, while the surrounding industrial density of the Katowice conurbation maintains persistently elevated background pollution throughout the year.
