London, Nov 20 (ANI): Slamming on car brakes could cause lung damage to motorists and pedestrians, says a new study.

The study, which involved lab tests, found that particles released by brake pads harm lung cells through a chemical process known as oxidative stress.

Reporting in the journal Particle and Fibre Toxicology, University of Bern researchers said that heavy braking was most harmful. But normal braking and even being close to a disengaged brake resulted in a potentially dangerous effect on body cells.

To reach the conclusion, boffins studied the effects of brake wear particles on cultured lung cells placed in a chamber close to a car axle, reports The Daily Express.

They concluded: Just as for exhaust particles, efforts to diminish brake particle emissions will lead to an improved ambient air quality and so could provide better protection of human health. (ANI)
