This work describes the results of a study started in 2007 to investigate the ultrafine particle (UFP) pollution in the urban area of Rome. The sampling site was located in a street with high density of autovehicular traffic, where measurements have shown that carbonaceous particulate matter represented an important fraction of aerosol pollution. UFPs have been classified using an electrostatic classifier. Monodisperse aerosol was either counted by ultrafine water-based condensation particle counter or sampled by means of a nanometer aerosol sampler. Samples collected were investigated using energy filtered transmission electron microscope in combination with energy dispersive X-ray spectroscopy and electron energy loss spectroscopy. Electron transmission microscope observations revealed that carbonaceous UFPs were present also as semi- transparent particles and nanotube related forms.
