Prešov's air quality reflects the Torysa river valley in the Slovak Eastern Carpathian foothills, with vehicle traffic on the D1 motorway and surrounding manufacturing industry contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the Carpathian highlands create topographic variation and cold winter inversions in the Prešov basin can concentrate heating and vehicle emissions during extended anticyclonic periods.
