Londrina's air quality reflects its position as a major Paraná agricultural and agribusiness capital, with vehicle emissions from the BR-369 and surrounding highway network and seasonal sugarcane and soy burning from the surrounding agricultural landscape contributing the primary pollution sources. The elevated plateau position at 585 metres generally aids background dispersal, while dry season burning events elevate regional PM2.5 across the broader northern Paraná agricultural belt.
