| Abstract | In the last years numerous epidemiological studies were carried out about particulate matter effects on human health. Even if there is no agreement among the epidemiological and toxicological studies about the importance of total particle concentrations in terms of number, area or mass having the major negative effects on human health, it seems that the aerosol number concentrations plays a predominant role. For this reason, international standards move the attention from PM(10) to PM(2.5) even if the number concentration is still not considered. In industrialized areas, the highest contribution to the fine and ultrafine particles comes from anthropogenic activities, namely from emissions of industrial combustion processes and traffic-related emissions (Cass et al., 2000). For this reason it is important to estimate the total particle number emission for each anthropogenic source and to understand the evolution of the particle size distribution (PSD) near these emission points. Zhu et al. (2004) have characterized the PSD evolution near major highway in Los Angeles showing the PSD seasonal trends and PSD evolution at different distances from the highways. Similar analysis were conducted by Kittelson on Minnesota highways (Kittelson et al., 2004). Fine et al., 2004 have obtained an ultrafine particle source apportionment in Los Angeles' industrial area. In this study the authors evaluate the PSD spatial and temporal variations in the San Vittore del Lazio industrialized area in Italy in which there are two main sources of emission: an highway and a municipal waste incinerator (MWI) plant. The main aim is to comprehend how these two sources can influence the background aerosol PSD of the area. In particular, an experimental campaign was carried out by means of a TSI 3936 Scanning Mobility Particle Sizer (R) (SMPS) and a TSI 3321 Aerodynamic Particle Sizer (R) (APS) Spectrometers. |
