“…The most attractive feature of XRF is its wide dynamic range, from parts-per-million (ppm or mg kg − 1 ) to 100%, for many elements present in a given sample (Hettipathirana, 2004). Portable x-ray fluorescence inherited the advantages of XRF, and is one of a few analytical techniques that are capable of in-situ analysis, providing chemical composition of a sample in a short period of time (30-120 s) to the operator in the field (Potts, 2008).…”

“…It is also quite complex and expensive, and takes a long time. Accordingly, since a rapid and appropriate analysis is critical for a successfully conducting the operation within a constructed time schedule, it is necessary to have an alternative advanced method to overcome these shortcomings of the test for soils [9].…”

The concentrations of Cu, Ni, Pb, Zn, and Cr in top soils (0-15 cm) from urbanized and rural areas of Iraq were measured by X-ray fluorescence analysis (XRF). The results revealed that soil samples located in urban areas had higher metal contents than did soil samples from rural areas. This was probably due to local pollution from increased population and other industrial sources.The comparison with the soil quality guidelines showed that metal concentrations in all the studied locations are lower than the permissible levels admitted by the World Health Organization (WHO).The mineralogical composition of the top soils, identified by X-ray diffraction (XRD), was predominantly Quartz, Calcite and minor minerals such as Dolomite, Feldspar and clay minerals. Total clay minerals in the soil samples, ranged from 3-10%, were found to be dominated by Montmorillonite, Kaolinite and Feldspar. The highest clay content was observed in Diala soils near the river Tigris.

“…Since the conventional and widely adopted EDXRF spectrometry directly uses unpolarized X-rays emitted from an X-ray tube as excitation radiation, the background level is high because of scattering of the X-rays from a sample. As a consequence, detection limits are degraded for trace elements especially in matrices consisted of light elements, such as plant materials, high silicate rocks and soils (Heckel et al 1992;Hettipathirana 2004).…”

A non-destructive analysis method for total bromine (Br) and iodine (I) contents in soil was established using polarizing energy-dispersive X-ray fluorescence (EDXRF) spectrometry. The matrix-corrected intensity of Br and I K X-rays from pressed pellets of soil powder samples was calibrated with their contents measured by inductively coupled plasma (ICP)-mass spectrometry after pyrohydrolysis preparation. The calibration curves for Br and I were successfully obtained in the concentration ranges 3.8-223 mg kg À1 and 0.91-54 mg kg À1 respectively. Repeated analyses of the same sample with polarizing EDXRF spectrometry within one day and after approximately 1.5 years showed good reproducibility of the measurement results. The lower limits of detection for Br and I were 0.14 mg kg À1 and 0.34 mg kg À1 respectively. The established analytical method for total Br and I contents in soil is non-destructive, simple and rapid, and is suitable for routine analysis. Trace elements such as rubidium (Rb), strontium (Sr), yttrium (Y), zirconium (Zr), niobium (Nb), cadmium (Cd), tin (Sn), antimony (Sb), caesium (Cs), barium (Ba), light rare earth elements and lead (Pb) were also measurable simultaneously under the identical operational conditions as those for Br and I measurements.
