Air pollution is responsible for 50,000 deaths every year in Brazil. In São Paulo alone, 6,400 residents lose their lives due to health complications caused by dirty air. São Paulo has pollution rates twice as high as World Health Organization (WHO) recommendations. The WHO’s exposure limit for particulate matter is 20 μg/m3 (microgram per cubic meter of air). This limit is surpassed in every monitoring station the city has, with some coming close to 40 μg/m3.
