Šentilj's air quality reflects its position in the Mura river valley on the Slovenian-Austrian border, with vehicle traffic from the busy A1 motorway border crossing and surrounding agricultural land contributing local sources. Winter residential wood burning adds seasonal PM2.5, while the open Mura valley generally allows better dispersal than more enclosed Slovenian valleys, keeping conditions moderate for most of the year.
