What affects air quality for runners in São Paulo
São Paulo's vast urban footprint and heavy vehicle activity make traffic emissions a persistent driver of local air pollution. Nitrogen dioxide peaks near major avenues and logistics routes, while fine particles can spread more broadly under low-wind conditions. Urban heat and dense development influence how quickly pollutants disperse.
