Lancaster's air quality reflects the Lune valley in northwest Lancashire, with vehicle traffic on the M6 motorway and the surrounding university and light manufacturing corridor contributing local sources. Atlantic westerlies from the Irish Sea generally provide adequate ventilation, while the Forest of Bowland AONB to the east and the Lake District to the north create topographic variation and Lancaster's relatively moderate industrial base maintains lower UK urban air quality readings than the neighbouring Blackburn-Preston industrial corridor.
