Nanoparticels from brake pads wear

Popis výsledku v původním jazyce

Exposure to particulate air pollution has been associated with a variety of health problems. One of the mainnsources of metal-rich airborne particulate pollution in roadside environments are brake-wear emissions. The nscanning electron microscopy (SEM) and transmission electron microscopy (TEM), Mössbauer spectroscopy n(MS), X-ray powder diffraction (XRD) was used to a make quantitative evaluation of wear particles in two nsamples. Sizes, morphologies, oxidation state, and trace element compositions of wear particles wereninvestigated using combination of several methods revealed high concentrations of Fe species and phases, noften associated with carbonaceous material. SEM and TEM observations show that brake wear particles with na size of tens to hundreds of nm mainly form particle agglomerates. However, ultrafine (<100 nm) particles are nlikely to pose a health threat after inhalation and/or ingestion.
