“…The PM 2.5 /PM 10 ratio has been calculated for Partisol samples at both sites, being 0.61 at EROS and 0.60 at BROS, which indicates anthropogenic emissions at these sites. PM elemental differences between background (EROS) and roadside (BROS) sites are plotted in Chung et al, 2006;Lim et al, 2010;Xia and Gao, 2010). The higher values observed for roadside Na + and Cl -might be traced to de-icing of salt or marine aerosol (Harrison et al, 2004).…”

El objetivo del presente estudio fue investigar las características constitutivas del material particulado (MP) recolectado tanto en un contexto urbano (sitio de observación de Elms Road, SOER) como en un sitio ubicado junto al camino (sitio de observación de Bristol Road, SOBR). Las muestras de MP fueron recolectadas en los sitios receptores del 28 de marzo al 11 de abril de 2012. Los parámetros estudiados incluyeron iones solubles en agua (Cl -, NO ) and trace metals (V, Al, Cr, Mn, Fe, Zn, Cu, Sb, Ba, Pb , K + and Fe regarding PM 2.5-10 , indicating roadside increments. The ionic and metal components of PM 2.5 at EROS constituted 44 and 7% of the total measured PM mass, respectively. The proportions of these species were 46 and 8% at BROS. For PM 2.5-10 , water-soluble ions and trace metal components represented 42 and 12% at EROS, and 56 and 11% at BROS.

“…Leaves are efficient accumulators of air particulates (Ma et al 2001;Chung et al 2005;Takashi et al 2005;Morales et al 2011). Freer-Smith et al (2004 reported foliar contamination was severe at roadsides and similar pollution with particulate matter occurs in urban and suburban cities of various countries.…”

Conventional methods that assessed the mercury (Hg) levels were not only an outcome of atmospheric pollution, but also the possibility of Hg contamination from the sample collection to laboratory analyses. Our studies used the direct mercury analyzer that measured Hg rapidly and precisely at ultra-trace concentrations with detection limit of 0.0015 ng g -1 on six favored desert plants and their surrounding soil in Kuwait. Analysis revealed elevated Hg concentrations in Tamarix chinensis Lour., and Salsola imbricate Forssk., among the chosen desert plants, especially during summer than in winter, thus labeling the qualities of a bio-indicator to Hg pollution. The overall parts-wise analysis on the six selected plants showed the elevated mean Hg concentrations in the leaves (0.89 ng g -1 ) followed by root (0.51 ng g -1 ) and stem (0.39 ng g -1 ) in the desert plants. Reasons attribute to the capability of these plant parts to absorb, accumulate, and assimilate Hg at varying concentrations. The overall mean Hg concentration was high in soil (2.24 ng g -1 ) in comparison with the mean Hg concentrations in the desert plants (0.60 ng g -1 ) irrespective of the two seasons. Translocation and bioaccumulation factors indicated low uptake of Hg translocation in the plant parts from the soil. Furthermore, the mean Hg concentration was found high in samples collected from Governorates (GIII) in comparison with the samples collected from other Governorates indicating the effect of pollution from various sources. The present study characterizes the selected plants as bio-indicators and also validates the impact of regional and seasonal variations to Hg pollution at ultra-trace levels in the arid ecosystem.

“…They also have serious influence on climate forcing, global warming and visibility [3,4]. In Indonesia, there are some routine air pollution monitoring, but the focus is still in total suspended particulate (TSP) or PM 10 (particles with aerodynamic diameters less than 10 µm). The long term published data on PM 2.5 (particles with aerodynamic diameter less than 2.5 µm) concentrations and compositions of airborne particulate matter is still scarce.…”

“…For this reason, the nuclear analytical techniques such as instrumental neutron activation analysis (INAA) and particle induced X-ray emission (PIXE) are widely used to analysis the filter samples of airborne particulate matters. Nuclear techniques have been applied to the characterization of particulate matter from air pollution in around the world [4][5][6][7][8][9][10][11][12]. Their high capabilities, simultaneous measurement, multi-elemental, high sensitivity, short analysis time and non destructive properties make them ideal for this type of work.…”

Urbanization and industrial growth have deteriorated air quality and are major cause to air pollution. Air pollution through fine and ultra-fine particles is a serious threat to human health. The source of air pollution must be known quantitatively by elemental characterization, in order to design the appropriate air quality management. The suitable methods for analysis the airborne particulate matter such as nuclear analytical techniques are hardly needed to solve the air pollution problem. The objectives of this study are to apply the nuclear analytical techniques to airborne particulate samples collected in Bandung, to assess the accuracy and to ensure the reliable of analytical results through the comparison of instrumental neutron activation analysis (INAA) and particles induced X-ray emission (PIXE). Particle samples in the PM 2.5 and PM 2.5-10 ranges have been collected in Bandung twice a week for 24 hours using a Gent stacked filter unit. The result showed that generally there was a systematic difference between INAA and PIXE results, which the values obtained by PIXE were lower than values determined by INAA. INAA is generally more sensitive and reliable than PIXE for Na, Al, Cl, V, Mn, Fe, Br and I, therefore INAA data are preffered, while PIXE usually gives better precision than INAA for Mg, K, Ca, Ti and Zn. Nevertheless, both techniques provide reliable results and complement to each other. INAA is still a prospective method, while PIXE with the special capabilities is a promising tool that could contribute and complement the lack of NAA in determination of lead, sulphur and silicon. The combination of INAA and PIXE can advantageously be used in air pollution studies to extend the number of important elements measured as key elements in source apportionment.
