UC Irvine study finds vehicle brakes emit up to 80% charged aerosol particles, posing a greater health risk than tailpipe emissions.

A UC Irvine study reveals that vehicle brakes emit up to 80% electrically charged aerosol particles, potentially posing a greater health risk than tailpipe emissions. Researchers discovered the high charged particles during experiments with detached brake rotors and calipers, spinning them in a large lathe and measuring the electric charge of emitted aerosols. These findings could contribute to efforts to reduce air pollution from vehicles.
