San Lorenzo's air quality reflects its position in the greater Asunción metropolitan area on the Paraguay River plain, with vehicle traffic on the Ruta 2 corridor and the light industrial character of this major university and residential satellite city contributing local emissions. The flat Paraguayan Chaco winds generally provide reasonable ventilation, while dry season burning from surrounding Chaco agricultural land contributes seasonal PM2.5, and San Lorenzo tracks above rural but below central Asunción levels.
