Metal particles from the abrasion of brake pads - up to a fifth of fine particulate matter (PM2.5) air pollution at roadsides - may cause inflammation and reduce the ability of immune cells to kill bacteria a new study has found, similarly to particles derived from diesel exhaust.

The scientists, primarily funded by the Medical Research Council (MRC), part of UK Research and Innovation, say this suggests that particulate pollution from brake wear could be contributing to increased susceptibility to airway infections and other negative effects on respiratory health.
