Car Exhaust Concentrations - Implications for Cyclists
A recent CFD study into the exhaust concentration in car wakes has revealed that certain rear car spoilers (or airfoils) can either disperse or concentrate pollutants at the same height as a following cyclist's head. The study "Spoiling Air Pollution Dispersion: A Numerical Investigation of Exhaust Plume Dispersion from Cars with Rear Spoilers" authored by A. McNabola, implies possible health implications for cyclists and pedestrians that follow behind cars.
Is now the time to move to electric vehicles?
Thanks goes to the San Francisco Chronicle for reporting this study.
