A report by the Boston-based Clean Air Task Force reported that commuters get 60 percent of their exposure to harmful pollution during the 6 percent of the day that they commute. That's particularly worrisome for us as cyclists, since we have no filtering system like cars with air-conditioning. Apparently Columbus was one of the cities that had information gathered for the study.
There is talk about requiring soot-reducing mechanisms on all diesel engines, but we'll see how that goes...
Does anyone know anything about face filters or any such thing for cyclists?
