There is a newly-found menace the roads that could be harming our health - brake pads road vehicles. Scientists have discovered that toxic dust and metal particles worn-out brake pads could have the same harmful impact our bodies as diesel emissions. King's College London found that fine dust released when a vehicle brakes could cause a number health problems. These include an inflammation the lungs, reduced immunity, an increased risk respiratory problems, and serious infections bronchitis or pneumonia. It is estimated that 93 per cent particulate pollution traffic comes from sources such as tyres, clutches and brake wear, and road dust.

The scientists say brake dust could be the cause a condition they have dubbed "London throat". Sufferers are the city dwellers who continually experience runny noses and irritating coughs and colds. These could be caused people inhaling the brake dust. Metal particles coat the lungs and prevent cells our immune system clearing harmful bacteria. Researcher Dr Ian Mudway said dust the various sources friction within vehicles casts doubt motor industry claims zero-emission cars. He said: "There is no such thing as a zero-emission vehicle. As regulations to reduce exhaust emissions kick , the contribution [sources such as brake dust] are likely to become more significant."
