Santa Cruz do Sul's air quality reflects its position in the Rio Grande do Sul tobacco farming plateau at 148 metres, with the British American Tobacco and Philip Morris international tobacco processing operations generating distinctive tobacco drying and curing emissions alongside vehicle traffic on the RS-287. The tobacco industry's seasonal curing operations between March and June represent the most distinctive local air quality contribution, while dry season burning from surrounding Rio Grande do Sul agricultural land adds seasonal PM2.5 variation throughout the year.
