Özet Türkçe :

The retention of zinc (Zn), copper (Cu), cadmium (Cd), lead (Pb), and arsenic (As) on rib bones belonging to 81 individuals gathered from the Resuloğlu necropolis, a Central Anatoli-an Early Bronze Age (EBA) excavation site, were analyzed. Graphite Atomic Absorption Spectrometry (GFAAS) was used for the assays of Pb and Cd. Furthermore, Cu and Zn were evaluated with Fast Sequential Atomic Absorption Spectrometry (FSAAS) while As was ana-lyzed using the hydride system. The ranges of Zn, Cu, Cd, Pb, and As levels were found be-tween 103.96- 837.34 ppm; 1.99-396.46 ppm; 0.13-2.95 ppm; 0.87-34.89 ppm; 0.35-36.43 ppm, respectively. The outcomes vary highly among age groups. In order to reveal the origin of the retentions, soil and water samples obtained from the different regions of the excavation area were also analyzed. Both bone/soil ratios for each element and proximity to the Resuloğlu region, in which rich Cu, Pb, Zn, Fe and Mn ore deposits can be found, support the notion that the origin of the accumulations arises from diagenetic effects. Yet, no influence of metal concentrations was found in water samples over the bones. For Cu retention, especially on bones, it is believed that the major factor behind the accumulation depends not only on diage-netic factors but also burial gifts.
