Deep investigation of ultrafine particles in urban air

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 semitransparent particles and nanotube related forms.

Frequency of occurrence of concentrations of air pollutants and their relationship to the established activities in Thriassion Plain – Greece
© Aristotle University of Thessaloniki (6/2009)
In many cases the understating of air pollution and air quality problems requires the knowledge not only of the actual concentrations of the air pollutants, but also of the frequency of occurrence of these concentrations. This information can be used to track the relationship between air pollutants’ concentrations and long-term changes over an area, such as the number of activities and their emissions.
