Air pollution: Tyre and brake fatigue compound an exhausting problem (OECD, Shayne MacLachlan, OECD Environment Directorate, Sep.8, 2016)
Today we review research into the impact of particles generated from tires and brake wear. The amount of particulate matter for an average urban arterial road with 25K vehicles per day can produce up to 9 kg of dust per km- bigger roads or highways with 100K VPD can produce four times that. Recycled tires from the billion cars in the road globally into materials used in playgrounds is being called the new asbestos. Banning petrol powered cars from cities to encourage e-cars and cycling means less emissions from the tailpipe and good for carbon emission reduction but it also means the same wear and particles from brakes and tires, in terms of air pollution and health, even from bicycles!
