“…In general, trace element concentrations are slightly more subject to variance because the sources are usually of an anthropogenic nature, and henceforth are highly dependent on the local sources of inputs (Amato et al 2009a). In general, the same trends can be observed in all size fractions for some of the trace elements as reported by Potgieter-Vermaak et al Table 2) displayed the highest concentration in the finest fraction with a steady decrease in concentration with increase in particle size (as also reported by Bian andZhu 2009 andFujiwara et al (2011)). In addition, it is noted that the absolute concentrations are lower for the May sampling campaign and the variance in concentration change can be observed in Figs.…”

Whilst vehicular and industrial contributions to the airborne particulate budget are well explored, the input due to building demolition is relatively unknown. Air quality is of importance to human health, and it is well known that composition of airborne particles can have a significant influence on both chronic and acute health effects. Road dust (RD) was collected before and after the demolition of a large building to elucidate changes in elemental profile. Rainfall and PM10 mass concentration data aided interpretation of the elemental data. Quantification of Al, As, Ba, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Rh, S, Si, Sn, Ti, V and Zn was carried out. It was found that only Al, K, Mg, Si and S increased in concentration across all size fractions after the building demolition. Risk assessment was then carried out on elements with applicable reference dose values to assess the potential health risks due to the demolition. Significant risk to children was observed for chromium and aluminium exposure. PM10, monitored 40 metres from the demolition site, indicated no abnormal concentrations during the demolition; however, rainfall data were shown to affect the concentration of PM10. The elemental data observed in this study could possibly indicate the role of increased sulphur concentrations (in this case as a result of the demolition) on the buffer capacity of RD, hence leaching metals into rainwater.

“…The particles whose main components were Ca or Si ( Fig. 3-2) could be regarded as calcite and quartz, respectively (Camatini et al, 2001;Fujiwara et al, 2011). In our case the presence of calcite could be associated with carbonate rock as a mineral filler, whereas the most probable source of quartz was traction sand.…”

“…During more than ten years, our group has conducted a series of studies aimed at determination, fractionation, and source identification of metals, metalloids, and ions in airborne particulate matter and related environmental matrices such as tree barks, road dust, and ashes [23][24][25][26][27][28][29][30][31]. In the framework of a new project, our interest in now focused on the contribution with information on the content of OPAHs and NPAHs in the…”

A C C E P T E D M A N U S C R I P T A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT ABSTRACTA study was undertaken to evaluate the content of oxygenated and nitrated polycyclic aromatic hydrocarbons (OPAHs and NPAHs) in airborne particulate matter (PM 2.5 and PM 10 ), and tree barks. For PM 2.5 and PM 10 collection different approaches were followed using different type of filters and sample collectors. Samples of PM 2.5 were collected on glass fiber filters during one month with a medium volume sampler. For PM 10 , glass and quartz fiber filters were used and samples were collected simultaneously for one week using a high volume sampler. In addition, bark samples were collected at the same sites.
