Bielefeld's air quality reflects its position in the Teutoburg Forest gap, where the city sits in the natural break in the Teutoburger Wald ridge that channels wind through the city. Vehicle traffic on the A2 Autobahn and the surrounding manufacturing industry are the primary local sources, while the ridge topography creates variation between the sheltered valley districts and the more exposed hillside areas in terms of pollution accumulation.
