União da Vitória's air quality reflects the upper Iguaçu river valley on the Paraná-Santa Catarina border at 840 metres, with vehicle emissions from the BR-476 and the surrounding timber, paper, and agribusiness operations contributing local sources in this highland border city. The elevated plateau position aids background dispersal, while cold winter temperature inversions in the southern Brazilian highlands and dry season burning from surrounding timber and agricultural operations contribute seasonal variation throughout the year.
