relationship between black carbon (bc) and heavy traffic

Mar 01, 2019 · 1. Introduction. Brazil is a big country (8.5 · 10 6 km 2) whose population (more than 200 · 10 6 inhabitants) is distributed mainly in the urban areas of the capital cities of the 26 States (over 90%). The density is not homogeneous, the most populated cities being situated in the coastal area. Most of the population is greatly affected by air pollution related mainly to road transport

impact of route choice and period of the day on cyclists

Cyclists are exposed to direct traffic emissions due to their proximity to on-road vehicles. Several studies associate black carbon (BC) exposure with both mortality and morbidity caused by cardiovascular and respiratory diseases. We did a comparative assessment of cyclists' exposure to BC in three cities: London, Rotterdam and São Paulo
