“…No obstante, se analizó también la matriz terrosa y como se observa en la Tabla 4 dichos metales también se encontraron en el sustrato, por lo que probablemente parte de los elementos registrados en los huesos proviniesen de una contaminación externa durante la diagénesis. Sin embargo, no se podía desechar la idea de que hubiera algún tipo de contaminación en vida del asno porque no se podían discriminar cuáles eran los elementos intrusivos ni qué cantidades provenían de la diagénesis (Carvalho & Marques, 2008;Carvalho et al, 2004;Patterson et al, 1991;Rebôcho et al, 2006;Zapata et al, 2006). Posteriormente se limpiaron utilizando el procedimiento descrito anteriormente, acetona y ácido acético, y los resultados de PIXE en la parte interna (T3 y F7) no mostraron trazas de Si, Mg, Al, K, Ti, Cr, Mn ni Pb, contrariamente a los resultados de los análisis realizados en las muestras que sólo fueron cepilladas (Tabla 4).…”

“…In vivo measurements X-ray fluorescence (XRF) is one of the major nondestructive tools for measuring lead and other elements in different media (Rebôcho, Carvalho, Marques, Ferreira, & Chettle, 2006;Valerio et al, 2014). In making use of this, it is important to note that the selection of tissue site is extremely important.…”

The measurement of lead in archaeological bone forms the basis for providing insight into ancient societies, including disease, lifestyle and eating habits. It is sometimes asserted that in the 5th century AD lead toxicity played a key role in the eventual fall of the western Roman Empire. Others view the effect of lead exposure at that time to be less significant. The debate concerns the idea that clinical lead poisoning mainly affected the aristocratic population and caused a strong reduction in fertility and reproduction .Choosing bone over soft tissues or blood for lead measurement is due to the fact that the bone represents a long-term store of a range of elements, including lead, and can survive over many thousands of years. Different elemental analysis techniques both in-vivo and in-vitro have been developed over the years, including X-ray fluorescence (XRF), the latter being the main technique described within this review. The main advantages of in-vitro techniques are that they have excellent detection limits and data processing times but on the down side they are very expensive. On the other hand, while in-vivo techniques are non-invasive they suffer from relatively poor detection limits, pointing to the need for validation using in-vitro analysis.

This article describes the applications of X‐ray fluorescence (XRF) as an analytical tool in forensic science, including its limitations and practical aspects. The use of XRF is specifically discussed for the analysis of materials of forensic interest such as metals, gunshot residues (GSRs), paint, glass, soil, fibers, plastic and general polymers, documents, and miscellaneous types of evidence. Developments such as biological tissues micro‐XRF, 3‐D micro‐XRF — an adaptation of micro‐XRF — and total XRF are also described. These specialized techniques have highly desirable characteristics for the elemental profiling of a wide range of forensic samples, and hence we can anticipate that they will find significant use in forensic laboratories in the future.
