Time to worry about car tyre pollution, Chris Whitty tells MPs

Chief medical officer says move to electric cars can reduce impact of exhausts, but may bring different problem to the fore

Ministers need to start looking seriously at the health risks from vehicle tyre wear as the impact of pollutants from car exhausts gradually reduces, Sir Chris Whitty has told MPs.

Giving evidence to the environmental audit committee, England's chief medical officer said improvements in emissions from petrol and diesel vehicles, and a shift towards electric cars, were reducing the extent of dangerous pollutants such as nitrogen oxides.
