Recent research highlights potential health risks associated with particles released from car brakes, raising questions about their impact.
Jess Thomson reports for Newsweek.
In short:
- New studies suggest particles from car brakes might be more harmful than exhaust emissions, composing a significant portion of air pollution.
- These particles are electrically charged, offering hope for easier removal from the air to mitigate health risks.
- The effects of brake-wear particles on health remain largely unknown, necessitating further research.
Key quote:
"The toxicity and health effects of brake wear particles are largely unknown... they may induce oxidative stress, but more research is needed."

Why this matters:
When drivers apply their car brakes, tiny particles from the brake pads shed off due to friction. This kind of pollution is concerning because these fine particles can penetrate deep into the lungs and even enter the bloodstream, posing significant health risks, including respiratory and cardiovascular diseases. In addition to this particulate pollution, our roads, especially during the warmer months, become unintentional contributors to air quality woes.
