“…This makes synchrotron radiation sources the brightest known sources of X-rays. The planar acceleration geometry makes the radiation linearly polarized when observed in the orbital plane, and circularly polarized when observed at a small angle to that plane [8,27]. In addition the third import property of this radiation is the high collimation level.…”

“…In addition the third import property of this radiation is the high collimation level. These characteristics are the main key for making the synchrotron radiation the most powerful tool for microanalysis, and mapping of elemental distribution in medical samples [27][28][29]. Synchrotron radiation has also been used with great success in TXRF techniques to study low elements analysis in biological applications [30].…”

“…However, the hair will have prolonged exposure to contamination and degrading effects over the decades to centuries or even millennia. [208][209][210][211] These interpretations are complicated by many factors. These can include breaking down of the proteins by hydrolysis and consumption by fungi or insects and other keratinolytic microbes.…”

Hair analysis as a biomonitor for toxicology, disease and health status

Hair analysis receives a large amount of academic and commercial interest for wide-ranging applications. However, in many instances, especially for elemental or 'mineral' analysis, the degree of success of analytical interpretation has been quite minimal with respect to the extent of such endeavors. In this critical review we address the questions surrounding hair analysis with specific intent of discovering what hair concentrations can actually relate to in a biogenic sense. This is done from a chemistry perspective to explain why and how elements are incorporated into hair and their meaning. This includes an overview of variables attributed to altering hair concentrations, such as age, gender, melanin content, and other less reported factors. Hair elemental concentrations are reviewed with regard to morbidity, with specific examples of disease related effects summarized. The application of hair analysis for epidemiology and etiology studies is enforced. A section is dedicated specifically to the area of population studies with regards to mercury, which highlights how endogenous and exogenous incorporation relies on species dependant metabolism and metabolic products. Many of the considerations are relevant to other areas of interest in hair analysis, such as for drug and isotopic analysis. Inclusion of a table of elemental concentrations in hair should act as a valuable reference (298 references).

“…Arsenic analysis of Napoleon I had been reviewed by Goldsmith [2] , where neutron activation analysis was used, and recently had been performed by Chevallier et al [12] and Carvalho et al [13] using the SR-XRF analysis. From these reports, arsenic analysis of hair is very problematic because of surface effects or contamination.…”

Forensic analysis of arsenic poisoning in Japan by synchrotron radiation X‐ray fluorescence

Synchrotron radiation X-ray fluorescence (SR-XRF) analysis reports of a poisoning case by arsenic, 25 July 1998, Japan, for forensic investigation purposes are reviewed. In these forensic analyses, SPring-8 and KEK-PF beamlines were used for minor element (Sn, Sb, Mo, Bi, Ba) analysis in the arsenic pesticide specimens, sampled at the crime scene as well as the neighborhood of the suspect. For this case, two kinds of documents were submitted to court: one was a qualitative analysis and said to be a 'pattern recognition' by Prof. Nakai, and the other was, by Profs Taniguchi and Hayakawa, a quantitative analysis after background subtraction, normalized by the sample thickness, where calibration curves were made with reference to the inductively coupled plasma atomic emission spectrometry (ICP-AES) analysis for reference samples. The final decision of the court was a death sentence based on the qualitative 'pattern recognition'. The present review concludes that the quantitative analysis by Profs Taniguchi and Hayakawa was scientifically more important than the 'pattern recognition' qualitative analysis, because the Taniguchi-Hayakawa report used novel but reliable data processing methods. The Sn, Sb, and Mo Ka intensities were normalized with respect to the As (major element) Ka (10.5 keV) intensity as a thick target, whereas the Bi and Ba Ka intensities were normalized by the Rayleigh scattering (for 116 keV incident beam) as a thin target. The Taniguchi-Hayakawa report was the first quantitative report in high-energy SR-XRF analysis. The most important conclusion in the present review is that the ICP-AES was more reliable over these SR-XRF analyses, because even the beamline selection was not possible without the knowledge of the impurity elements obtained by the ICP-AES. Five elements (Se, Sn, Sb, Pb, and Bi) were used in ICP-AES for identification compared with only three elements (Sn, Sb, and Bi) in SR-XRF. High blank intensity resulted from using Pb for X-ray collimator in the beamline. Overlapping of the analytical lines of minor Se and major As prevented the use of Se for identification. Recent analysis of Fe, Zn, Mo, and Ba in Nakai's raw spectra measured in 1998 reveals the arsenic stored in the kitchen of the condemned criminal in the death row was significantly different from that of the paper cup used for poisoning.
