There are many proud commuters choosing the bike for their daily duty stroke. Maybe some bike commuters think it aids their concentration, makes them alert in the morning or it is better for their conscience. For sure, some bike commuters think exercise in the morning improves their physical health. In fact, there are not only advantages. There is also a downside. Bike commuters are exposed to multiple air pollutants, in particular in urbanized areas. This information is not completely new. But do you think that the right choice of your route reduces the exposure to air pollution? You think an alternative route is more healthy? Probably, the following information is a bit disappointing for bike commuters.
A new study in Fort Collins tries to appraise how the route selection influences personal exposure to air pollutants. The researchers analyzed the exposure of the following air pollutants: Black carbon (BC), ultrafine particle number concentration (PNC), carbon monoxide (CO), and fine particulate matter (PM2.5). For the study, 45 participants in the Fort Collins area (Colorado, United States) were investigated for a period of eight days. They completed eight days of commuting by car and bicycle on direct and alternative routes with reduced traffic.
