Zwolle's air quality reflects its position in the Overijssel IJssel-Vecht river delta, with vehicle traffic on the A28 and the surrounding logistics and agri-food manufacturing industry contributing local sources in this northeastern Netherlands regional capital. The flat Dutch river plain provides reasonable wind dispersal on most days, while the broader Rhine-IJssel regional background pollution and consistent North Sea westerlies provide the primary ventilation, generally maintaining Zwolle at moderate Dutch urban air quality levels throughout the year.
