Brake pads could harm our immune system

Brake pads are a new danger on the roads. Scientists discovered that toxic dust and metal from brake pads could harm our bodies as much as diesel emissions. The fine dust released when a car brakes could inflame the lungs, reduce immunity, and cause serious infections like bronchitis or pneumonia. Scientists estimate that 93 per cent of particulate pollution from traffic comes from tyres, clutches, brake pads, and road dust.

Scientists say that inhaling brake dust could cause "London throat". This causes runny noses, coughs and colds. Metal particles from brakes cover the lungs and stop cells in our immune system from removing bad bacteria. Brake pad dust casts doubt on claims by the motor industry of there being zero-emission cars. A researcher said: "There is no such thing as a zero-emission vehicle." He said the brake dust problem is going to get worse.
