Chapecó's air quality reflects its position in the Santa Catarina western plateau at 670 metres, with vehicle emissions from the BR-282 and the surrounding poultry and pork processing industry — making Chapecó Brazil's meatpacking capital — contributing elevated ammonia, biological particulates, and odour alongside vehicle NOₓ. The elevated plateau position aids background dispersal, while dry season burning from surrounding agricultural land contributes seasonal PM2.5 variation, and the intensive animal farming operations represent Chapecó's most distinctive local air quality challenge.
