Contagem's air quality is significantly influenced by its position as one of Belo Horizonte's most industrialised western municipalities in the Belo Horizonte metropolitan basin, with steel, automotive, and manufacturing plants in the Cidade Industrial district generating elevated PM2.5 and NOₓ. The enclosed bowl topography of the Belo Horizonte basin limits dispersal under calm conditions, particularly during the dry season winter months.
