Łomża's air quality reflects the flat Podlaskie Narew river valley in northeastern Poland, with vehicle traffic on the Via Baltica S61 and the surrounding agricultural and light manufacturing industry contributing local sources. Winter residential wood and heating oil burning generates seasonal PM2.5 elevation, while the flat Mazovian-Podlaskie plain generally allows reasonable wind dispersal on most days and the relatively low industrial base compared to southwestern Poland means Łomża tracks below Silesian levels throughout the year.
