Araucária's air quality faces significant industrial challenges from the Petrobras REPAR petroleum refinery, Paraná state's largest refinery, generating elevated SO₂, benzene, and industrial PM2.5 in the greater Curitiba metropolitan southern corridor. The surrounding Curitiba metropolitan plateau at 906 metres aids background dispersal, while the refinery's scale and the surrounding petrochemical industrial district make Araucária one of southern Brazil's more industrially impacted municipalities, with the REPAR complex representing the dominant local air quality influence throughout the year.

In Araucária, reduced air quality is most noticeable when eucalyptus and native Atlantic Forest species pollen peaks, and on days affected by the Petrobras REPAR petroleum refinery, Paraná state's largest refinery; the rest of the year typically brings clearer, more consistent conditions.
Are air quality levels in Araucária based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
