The particles have variable composition, more details in the article.
NEEVE Progress in the characterization of non-exhaust particulate emissions.
The NEEVE project continues advancing in the characterization of non-exhaust particulate emissions. Recent analyses of cyclone particulate samples under the Scanning Electron Microscope (SEM) reveal valuable insights into their composition and morphology.
The particles show variable compositions, with carbon contents between 44–86%, and zinc as the dominant metal (6–31%).
Other detected elements include Na, Si, Al, S, Fe, Sn, Ba, and Mg in minor concentrations.
These findings contribute to a better understanding of the chemical nature of brake and tire wear particles, a crucial step toward reducing non-exhaust emissions and improving air quality.
