Alphen aan den Rijn's air quality reflects the Dutch Randstad Green Heart between Amsterdam and Rotterdam, with vehicle traffic on the N11 and surrounding greenhouse agriculture contributing local sources. The flat Dutch polder landscape provides reasonable dispersal, while North Sea westerlies carry relatively clean Atlantic air and greenhouse gas heating contributes localised NOₓ distinctive to this horticultural area.
