Elemental analysis using portable X-ray fluorescence: Guidelines for the study of dry human bone
Objective
X-ray fluorescence (XRF) is a non-destructive technique that measures the elemental concentration of different materials, including human bone. Recently, it began to be applied to paleopathological studies due to the development of portable devices and their relative ease of use. However, the lack of uniform procedures hampers comparability and reproducibility. This paper aims to provide guidelines for an efficient and standardized evaluation of bone elemental composition with a portable XRF (pXRF) device.
Materials
This technical note is based on the application of the Thermo Scientific Niton XL3t 900 GOLDD+.
Methods
This work includes suggestions for the choice and preparation of human bone samples, both from archaeological context and documented collections, and methodological procedures in pXRF setup, such as choice of calibration, assessment of accuracy, and analysis run time. Additionally, recommendations for data validation and statistical analysis are also included.
Conclusions
This technique has great potential in paleopathology since bone chemical variations may be associated with different pathological conditions, environmental contamination (e.g., lead), and/or administered treatments, such as mercury. Following an expected increase in the number of studies, it is essential to establish good practices that allow results from different researchers to be comparable.
Significance
X-ray fluorescence is a non-destructive technique that measures small concentrations (ppm) of elements from magnesium (12Mg) through bismuth (83Bi).
Limitations
pXRF does not detect elements lighter than Mg, and its lower energy excitation penetrates less than other techniques.
Suggestions for further research
Other research groups should test these guidelines and comment on their usefulness and replicability.
期刊介绍：
Paleopathology is the study and application of methods and techniques for investigating diseases and related conditions from skeletal and soft tissue remains. The International Journal of Paleopathology (IJPP) will publish original and significant articles on human and animal (including hominids) disease, based upon the study of physical remains, including osseous, dental, and preserved soft tissues at a range of methodological levels, from direct observation to molecular, chemical, histological and radiographic analysis. Discussion of ways in which these methods can be applied to the reconstruction of health, disease and life histories in the past is central to the discipline, so the journal would also encourage papers covering interpretive and theoretical issues, and those that place the study of disease at the centre of a bioarchaeological or biocultural approach. Papers dealing with historical evidence relating to disease in the past (rather than history of medicine) will also be published. The journal will also accept significant studies that applied previously developed techniques to new materials, setting the research in the context of current debates on past human and animal health.
