“…Depending on the characteristics of the burial site and surrounding soil type and its content, post-mortem alterations can affect the chemical profile of osseous materials to an extent. The extent of diagenesis is assessed by the calcium-phosphorus ratio that indicates bone integrity (Zapata et al, 2006;Shafer et al, 2008;János et al, 2011). However, even in cases where a native Ca/P ratio (~ 2.16) can be measured for ancient bones, some studies still refer to significant bone compositional changes (e.g.…”

As an important mineral source for the entire organism, bone serves as a useful bioarchive for monitoring past human lifeways like diet, since the concentration of the elements in its structure is influenced by the individual diet. Human and animal bones from three different Neolithic Levels (Level 5, 4, and 3) dated to 6800 and 6100 cal. BC according to the C14 found in Tepecik-Çiftlik, Central Anatolia, were elementally (Ca, P, Mg, Mn, Sr, Zn, Cu, and Pb) investigated by the help of X-ray fluorescence (XRF) spectrometry. The element content of bones refers to post-mortem alteration (diagenesis), especially for manganese and lead. Bivariate treatment of the element with calcium (element/calcium ratio) seems to demonstrate some differences between adult and subadult, male and female, and among levels. Multivariate analysis (PCA and DA) suggests a shift from meat consumption and rich subsistence economy in the lower levels to more vegetable (cereal) consumption and poor economy in the upper level. The results obtained from multivariate treatments are in agreement with the findings of archaeologists and anthropologists who conducted the excavations. Keywords: trace elements, heavy metals, Neolithic populations, paleodiet, ancient bone, central Anatolia Öz Organizma için önemli bir mineral kaynağı olan kemiğin yapısında yer alan elementlerin derişimi beslenmeden etkilenebildiğinden, kemik diyet gibi geçmiş insan yaşam biçimlerini izlemek için yararlı bir biyolojik arşiv görevi görür. Orta Anadolu Bölgesinde yer alan Tepecik-Çiftliğin C14 tarihlemesine göre yaklaşık 6800-6100 yılları arasına tarihlenen üç farklı Neolitik Tabakasından (Seviye 5, 4 ve 3) elde edilen insan ve hayvan kemiklerinin element (Ca, P, Mg, Mn, Sr, Zn, Cu ve Pb) içeriği X-ışını fluoresans (XRF) spektrometrisi yardımıyla incelenmiştir. Kemiklerin element içeriği mangan ve kurşun başta olmak üzere gömü sonrası değişime işaret etmektedir. Elementlerin kalsiyum ile (element/kalsiyum oranı) bivaret analizi yetişkin ile yetişkin yaş altı, kadın ile erkek bireyler ve tabakalar arasında farklılıklar olduğunu göstermiştir. Çok değişkenli analizler (PCA ve DA) alt katmanlarda et tüketiminden ve zengin geçinim ekonomisinden üst tabakada daha fazla bitki (örneğin tahıl) tüketimine ve fakir geçinim ekonomisine geçiş olduğunu göstermektedir. Çok değişkenli incelemelerden elde edilen sonuçlar, kazıları gerçekleştiren arkeologların ve antropologların bulguları ile uyumludur.

“…El estado de conservación de los huesos era malo y debido a su elevada porosidad presentaban una alta cantidad de partículas procedentes del suelo en el interior de su estructura; de esta forma se podría comprobar hasta qué punto son efectivos los procedimientos de limpieza. Se extrajeron muestras de unos dos centímetros de tamaño de ambos huesos y fueron tratadas siguiendo diferentes protocolos basados en los trabajos de Carvalho et al (2004), Price et al (1992) y Shafer et al (2008). Los tratamientos de limpieza pueden resumirse en cuatro pasos: Paso 1: Lavado por inmersión en agua destilada en una cubeta de ultrasonidos durante 15 minutos para eliminar los restos de matriz terrosa de la muestra.…”

“…Durante este proceso se pierde la materia orgánica y se producen cambios en la cristalinidad y porosidad, pudiéndose detectar variaciones en propiedades químicas relacionadas con la disolución, precipitación, absorción, sustitución de minerales y recristalización (Carvalho et al, 2004). En relación con todos estos procesos, Shafer et al (2008) establecen dos tipos principales de contaminación de los huesos durante la fosilización: oclusión e intrusión de partículas del suelo en los poros, y absorción y reemplazamiento de algunos elementos en la estructura ósea. En este sentido es destacable el estudio bioestratinómico realizado por Trueman et al (2004) en el Parque Nacional de Ambosely (Kenia), donde se describen los diferentes minerales (barita, calcita, trona, crandalita y probablemente sepiolita) que se incorporan al hueso antes del enterramiento.…”

“…Por lo tanto, en los estudios de elementos traza de huesos subfósiles es importante destacar la incorporación de algunos de estos elementos durante el proceso de fosilización (Kyle, 1986) y es por eso que el objetivo principal de este trabajo es diseñar un protocolo de preparación de muestras que asegure la eliminación de ese aporte químico diagenético antes de realizar el análisis mediante la técnica PIXE. Una técnica que no siendo la más común en este tipo de estudios (Shafer et al, 2008), es aplicada en el análisis de muestras óseas arqueológicas (Elliott & Grime, 1993;Gaschen et al, 2008;Goodwin et al, 2007;Müller & Reiche, 2011;Reiche et al, 1999) y presenta la ventaja de ser una técnica no destructiva.…”

Paleodietary Analysis of Human Remains from a Hellenistic-Roman Cemetery at Camihöyük, Turkey

The presence of copper, zinc, magnesium, iron, lead, molybdenum, manganese and nickel was discovered on 22 human ribs in a Hellenistic-Roman cemetery located in the ancient city of Camihöyük, Turkey. The levels of each element found in the males were higher than those in females, except iron. Copper, magnesium, iron, molybdenum, and nickel levels were measured to be higher in the soil than in the skeletons, whereas the other elements were higher in the human skeletons. Lead was not traced in the soil, but on the skeletons. These individuals had probably been exposed to this element during their lives due to higher consumption of vegetables than meat.
