“…The average EF values for the detected elements in PM 2.5 samples during the three sampling periods are reported in Table and displayed in Figure . The EF values of some soil‐related elements like Al, Si, Ti, and Fe were ≤3 during all sampling periods, indicating little or no anthropogenic influence as it was found in several cities of ARASIA (Arab countries in Asia) in a previous study . EF for Na, a sea‐salt tracer, was <2, and this is expected in a non‐coastal city like Amman (more than 60 km away from sea).…”

“…Samples were collected using ISAP® 1050e sampler, capable of collecting air particulate samples in three stages; fine particulate matter PM 2.5 , coarse particulate matter PM 10–2.5 (aerodynamic diameter between 2.5 and 10 μm), and particulate matter of aerodynamic diameter larger than 10 μm (>PM 10 ), with constant flow rate at 2.3 m 3 /hr. The three different stages of the ISAP sampler have been described elsewhere . Only PM 2.5 samples were collected on pre‐weighed and pre‐conditioned thin Teflon filters (47‐mm diameter, 46‐μm thickness, and 2‐μm pore size) supplied by PALL corporation .…”

Aerosol sampling was carried out prior to and during an active construction work at the University of Jordan in Amman, Jordan. Elemental characterization for 60 PM2.5 samples was performed by particle‐induced X‐ray emission (PIXE) technique at the LABEC laboratory of INFN in Florence, Italy. Twenty three elements (Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, Zr, Ba, and Pb) were detected, and their concentrations were assessed during three sampling periods, namely, “No Construction,” “Pouring Concrete,” and “Bleaching.” The results showed higher concentrations of soil‐related elements and lower concentrations of anthropogenic‐related elements during construction periods compared with their concentrations before construction. Soil‐related elements showed very low enrichment factor (EF) and high correlation coefficients during all sampling periods. Anthropogenic‐related elements were very much enriched and correlated only during the first sampling period “No Construction.”

Study of the uniformity of aerosol filters by scanning MA‐XRF

et al. 2017

Energy-dispersive X-ray fluorescence (XRF) is an attractive analytical method to determine the level of air pollution by heavy metals. The concentration of the filter in ng/cm 2 is obtained by direct comparison of the net characteristic line intensity of an element with that of a thin film standard. As the sampled area on the filter and the area of the standard are larger than the area analysed by the instrument, the distribution of the elements on the surface of both samples and standards have to be sufficiently uniform. If this is not the case, biased concentration estimates are obtained. Two scanning macro-XRF setups with a beam diameter of~0.5 mm were used to investigate the distribution of elements in (1) commercially available (Micromatter) standards, (2) in-house quartz filter standards obtained with an aerosol generator and (3) particulate matter (PM 10 ) collected on quartz filters by a Leckel SEQ 47/50 sampler. The uniformity of the Micromatter standards was better than 2%. At least some in-house standards showed a concave distribution with less material at the edges. The maximum bias introduced by this is less than 5%. Because of the limited sensitivity of scanning XRF compared with conventional XRF, the distribution of only a few common elements like Ca and Fe could be determined reliably in aerosol filters. The distribution of some heavy elements could only be measured in filters sampled in polluted regions. In general, the loading of particulate matter over the filters was uniform.

The University of Jordan Van de Graaff accelerator (JUVAC) was devoted many years ago to promote scientific research through the installation of several beamlines based on nuclear techniques. It constitutes the first and unique, till now, ion beam analysis facility in Jordan. Among these techniques, the JUVAC has recently installed, with the financial and technical aid of the International Atomic Energy Agency, a combination of particle‐induced X‐ray emission (PIXE) and Rutherford backscattering spectrometry (RBS). A new X‐ray detector has been installed, and the system has been tested for aerosol analysis using a set of thin MicroMatter standards. This manuscript includes a brief description of the combined PIXE–RBS beamline with some results, particularly those obtained by PIXE. The low‐energy proton beam adds a technical limitation to attain optimum analytical performance. However, a simulation of the RBS spectrum of protons on aerosol filter indicates that the RBS measurement for some elements (e.g., Pb) can replace the PIXE one.
