Opname van Fijn Stof in de longen van fietsers

Blootstelling aan fijnstof in het verkeer: een vergelijking van fietsers en autopassagiers

Een studie uitgevoerd door het VITO Mol, Vlaamse Instelling voor Technologisch onderzoek (Luc Int Panis, Hanny Willems, Bart Degrauwe, Nico Bleux, Vinit Mishra) in samenwerking met IMOB, Instituut voor Mobiliteit - Universiteit Hasselt (Luc Int Panis), Menselijke Fysiologie en Sportgeneeskunde, Vrije Universiteit Brussel (Bas de Geus, Romain Meeusen) en C.O.R.E en departement geografie, Katholieke Universiteit Leuven (Grégory Vandenbulcke, Isabelle Thomas)

Wij citeren:
Quantities of particles inhaled by cyclists were between 400 and 900% higher compared to car passengers on the same route. The longer duration of the cycling trip also increased the inhaled doses.

The results presented in this paper should be seen as an opportunity to improve cycling conditions. Given the fact that people who choose to cycle contribute to better air quality,  policies and measures should first target the motorized traffic that is a cause of air pollution and focus on reducing exposure (rather than concentrations) to prevent unwanted health effects. In a forthcoming paper we will disaggregate the measurements along the routes to study the effects of small scale attributes of the road lay-out on exposure and use the dataset to derive individual optimised cycling speeds. The results of this study will likely have interesting implications for the planning of cycling infrastructure. Any measure that increases the distance between cyclists and tail-pipes will help to reduce exposure. Identifying and implementing separated and dedicated routes for cyclists and motorized traffic will go a long way in decreasing exposure but will likely not offset the entire exposure difference. However we hypothesize that it is unlikely that this would completely offset the health benefits of cycling.
