“…In general, fluoropolymer or cellulose membrane filters have been used for multi-elemental analysis because these kinds of filters usually contain very little amount of inorganic impurities (Calzolai et al, 2008;Niu et al, 2010;López et al, 2011;Öztürk et al, 2011). On the other hand, quartz fiber filters (QFFs) have not often been used because they are considered to contain silicon and many other metal impurities (Baron and Willeke, 2001).…”

It would be convenient if we could achieve multi-component (organic and inorganic species) analysis using just one quartz fiber filter (QFF) as an aerosol collection medium. In general, QFF have been used for analyzing carbonaceous materials in aerosols. This study shows a nondestructive, rapid, and simple method using EDXRF (Energy Dispersive X-Ray Fluorescence spectrometry) that has secondary targets and three-dimensional polarization optics for analyzing inorganic multi-elements in aerosols collected on QFFs. Multi-element analysis can be achieved by using EDXRF coupled with fundamental parameter (FP) quantification, as speed of up to 900 s (15 min) per sample. The EDXRF-FP method shows good repeatability, with generally less than 5% variation when measuring each analyzed element. While the elemental concentrations in the blank QFFs in any lots examined in this study could be considered to be lower than the actual samples, the blank level of Ni cannot be ignored. The EDXRF-FP results for each element of the aerosols collected on QFF agreed well with ICP-MS and ICP-AES results. The temporal variations of the selected elements in aerosols obtained by EDXRF-FP showed very good agreement with those obtained by ICP-MS and AES, and thus this method is suitable for elucidating day-to-day variations of multi-elements in aerosols.

“…Elemental composition of the aerosols in Córdoba City has been reported in López et al (2011). Anthropogenic sources have been shown to be the main responsible of the particulate matter minor than 2.5 µm in aerodynamic diameter, while elements with crustal origin are increased in the particulate matter minor than 10 µm in aerodynamic diameter.…”

Ice nucleation in the atmosphere is of practical and fundamental importance since ice crystals influence the release of snow, rain and hail. Suspended aerosols in the atmosphere typically initiate freezing at temperatures below −15 °C; although occasionally freezing occurs at higher temperatures. In this work we describe an experimental device designed to measure the concentration of natural ice nuclei under controlled temperature and supersaturation conditions. The measurements were performed at Córdoba City, for temperatures between −15 °C and −30 °C and the sampled air was supersaturated with respect to ice and subsaturated with respect to liquid water; under these conditions the deposition ice nuclei were quantified. There are few studies reported in the literature regarding measurements of deposition ice nuclei concentration and, to our knowledge, there are no previous laboratory data of this kind of ice nuclei for T < −20 °C. The results show that the number of deposition ice nuclei increases at colder temperatures and higher supersaturations. These results are in general in good agreement with results previously reported by other authors. A fitting function which depends on temperature and supersaturation is proposed to parameterize the results obtained in the present work

“…PC 3 explains 13 % of the data variance and is significantly characterised by Zn (0.85), with moderate contributions of Be (0.59) and Na (0.57). Zn is considered a good marker for tyre wear emissions (Salvador et al, 2007) as well as tailpipe emissions, due to its use in motor oil (López et al, 2011). Moreover, Zn and Na have been found in particulate matter released during wood combustion, especially bark combustion (Jöller et al, 2007).…”

Abstract.A PM 1 (i.e. particulate matter with an aerodynamic diameter less than 1.0 µm) short-term monitoring campaign was carried out in the Agri Valley (southern Italy) in September 2012. This area is of international concern, since it houses one of the largest European on-shore reservoirs and the largest oil/gas pre-treatment plant (i.e. the Centro Olio Val d'Agri -COVA) within an anthropised context. PM 1 measurements were performed in Viggiano, the nearest town to the COVA plant and one of the most populated towns of the Agri Valley. During the study period, the PM 1 daily concentrations ranged from 1.2 to 8.4 µg m −3 , with a mean value of 4.6 µg m −3 . Regarding the PM 1 chemical composition, it can be observed that S and typical crustal elements were the most abundant constituents of the PM 1 collected. By applying principal component analysis (PCA), it was pointed out that crustal soil, biomass and wood burning, secondary atmospheric reactions involving COVA plant emissions and local soil particles, and traffic were the main sources contributing to the PM 1 measured in the area under study. Moreover, a possible contribution of the long-range transport of African dust was observed.
