The following map shows the average exposure of cyclists to air pollution (Black Carbon) on the street of Antwerp. The most healthy cycle routes are depicted in green. The BC map shows measured black carbon concentrations averaged over street sections. The map is based on BC measurements collected by 3 teams of city guards over a 12 month period. As more data are collected the map becomes more detailed and reliable. Be aware that this map is not validated and is only presented as an illustration of the possibilities. The density map indicates which areas are well covered and which aren't.
