Chełm's air quality reflects the flat Lublin Upland in eastern Poland near the Ukrainian border, with vehicle traffic on the S12 expressway and the surrounding chemical and cement manufacturing — including the Chełm cement works — contributing elevated industrial dust alongside residential coal burning. The flat Lublin-Chełm plain provides reasonable dispersal on most days.
