Cyclists map Antwerp’s air pollution (Belgium)

Cyclists with pollution monitors and GPS trackers attached to their bicycles have produced detailed maps of Antwerp’s air quality, as part of a recent study.  

Researchers equipped cyclists with specially modified bicycles and sent them on two fixed routes in the city centre to measure their exposure to high levels of ultrafine particles. These particles and black carbon have been linked to health issues such as respiratory and heart problems.
