Delft's air quality reflects the Dutch Randstad position between The Hague and Rotterdam, with vehicle traffic on the A13 motorway and the surrounding technology research and TU Delft campus contributing local sources. North Sea westerlies provide maritime ventilation, while the flat Dutch polder landscape allows reasonable dispersal and the Rotterdam industrial complex upwind elevates background PM2.5 and NO₂ above typical Dutch coastal values.
