Yambol's air quality reflects the Tundzha river valley in southeastern Bulgaria, with vehicle traffic on the surrounding road network and agricultural operations contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the flat Thracian plain to the west generally allows reasonable wind dispersal and the Strandja and Sakar mountain ranges to the east and south create topographic variation throughout the year.
