“…The same evidence was obtained in a coordinated campaign, specifically devoted to the study of PM1, conducted in three Italian towns in 2004 (Vecchi et al, 2008). The elemental composition looks similar at all sites with two exceptions: 1) particularly high Fe concentration values can be observed in Cornigliano, where a steel smelter plant was operating (at this site only, Fe has a higher concentration than S); 2) Multedo, the only site where Ba and Mo, tracers of traffic (De Miguel et al, 1997), could be observed Fig. 2 -Average PM composition measured by XRF on PM10 (top), PM2.5 (middle) and PM1 (bottom) samples in the sites quoted in Table 1.…”

Daily time series measurements of elements or compounds are widely used to apportion the contribution of specific sources of particulate matter concentration in the atmosphere. We present results obtained for the urban area of Genoa (Italy) based on several hundred of PM10, PM2.5 and PM1 daily samples collected in sites with different geo-morphological and urbanization characteristics. Elemental concentrations of Na to Pb were obtained through Energy Dispersive X-Ray Fluorescence (ED-XRF), and the contributions of specific sources of particulate matter (PM) concentration were apportioned through Positive Matrix Factorization (PMF). By sampling at different sites we were able to obtain, in each PM fraction, the average and stable values for the tracers of specific sources, in particular traffic (Cu, Zn, Pb) and heavy oil combustion (V, Ni). We could also identify and quote the contamination of anthropogenic PM in "natural" sources (sea, soil dust). Sampling at several sites in the same urban area allowed us to resolve local characteristics as well as to quote average values. IntroductionIn recent years, atmospheric aerosols have been studied extensively (Charlson et al., 1992;Harrison et al., 2001;Satheesh and Moorthy, 2005 , 2002a,b;Stieb et al., 2002;Fernandez et al., 2003).Up to now, PM concentrations have been routinely monitored. However, this level of monitoring is insufficient and a measurement of the elemental and chemical composition of PM is recommended in order to achieve a more complete picture. Indeed concentration limits have been set in Europe for some toxic elements (Pb, Ni, Cd, Hg; see the recent European Directive 2004/107/CE). Element and/or compound measurements can also help to trace specific emission patterns. Thus, the knowledge of the chemical composition of particulate matter can be used to evaluate the impacts of the various pollution sources on air quality. Several "source apportionment" strategies have been developed; receptor models (Gordon, 1988) are presently considered the most effective approach. These models usually provide three pieces of information: the number of (major) sources of particulate matter, the source profiles and the mass contribution of each source to total PM. These models single out groups of elements with correlated concentration trends, which

“…Mn and Cr in atmospheric particles are widely considered as source indicators of road dust (Manoli et al, 2002). Besides, Co is a constituent of urban source of dust (Miguel et al, 1997). Thus, it is not surprising to observe the higher concentrations of Co, Mn and Cr in 2011 relative to those in 2001.…”

“…of each city determines the metal concentration in dust samples. 23,24 But in the absence of knowledge regarding activities or characteristics of the sampling sites in the various cities or countries, comparison of data recorded and comments on the causes of the differences between metal levels may be unjustified. However, the results from this study revealed that the mean levels of Zn, Cu and Pb were found to be significantly lower than the reported values of various cities ( Table 3).…”

Street dust has been sampled from eight major locations of Kathmandu city. The samples were separated into three particle size fractions (<425, 425-600 and >600 μm) and analyzed for Pb, Cu, Zn and Fe using Atomic Absorption Spectrophotometric method. Results revealed that the bulk samples as well as all particle size fractions under investigation were found to have the metal abundance order as Fe > Zn > Cu > Pb. However, the trace metal concentrations increased with the decrease of dust particle size in all samples. About 35-68% of heavy metals were associated with the small particle size fraction (<425 μm) and this particle size accounted for 64-81% of the total mass of street dust from all locations. The smaller particle size fraction has a higher heavy metal content, low density, high mobility in runoff, and thus is a higher risk for the residents of Kathmandu city. From the present study, we conclude that a monitoring plan and a suitable risk assessment are necessary to evaluate the evolution of metal concentration in dust in order to develop the proper measures for reducing the risk of inhalation and ingestion of dust for humans and environment.
