Shumen's air quality reflects the Shumen plateau in northeastern Bulgaria, with vehicle traffic on the A2 motorway and surrounding manufacturing and agricultural operations contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the flat Danube plain to the north generally allows reasonable wind dispersal and the Shumen hills to the south create topographic variation that influences local pollution accumulation throughout the year.
