Abstract (2. Language): 
In this study, rib bones belonging to 17 individuals excavated from Adramytteion(Örentepe, Balıkesir), an ancient Western Anatolia settlement, were analyzed in order to detect the retention of zinc (Zn), copper (Cu), cadmium (Cd), lead (Pb) and arsenic (As). Graphite Atomic Absorption Spectrometry (GFAAS) was used for the analysis of Pb and Cd. Cu and Zn levels were determined using Fast Sequential Atomic Absorption Spectrometry (FSAAS). Hydride System Atomic Absorption Spectrometry (HSAAS), however, was used for As retention. The ranges of Zn, Cu, Cd, Pb and As were 97,55-391,59 ppm; 32,92- 56,63 ppm; 0,20-2,72 ppm; 8,08-44,98; 17,05-54,35 ppm, respectively. Moreover, soil and water samples gathered from the excavation area were analyzed to interpret the origin of metal accumulation. When taken into account bone/soil ratios of the metals and proximity to the ore deposits, diagenetic effect as a fundamental determiner is thought the main reason behind such higher concentrations traced on bones. On the other hand, it was found that water was not one of the sources related with this retention. Considering higher Cu retention in terms of metal/soil ratio, more researches are needed about the lifestyle of Adramytteion population to understand the reasons better.
Abstract (Original Language): 
Bu çalışmada bir Batı Anadolu Erken Bizans Dönemi antik yerleşim alanı olan Adramytteion (Örentepe, Balıkesir) kazı alanından çıkarılan 17 bireye ait kaburga kemiklerinden alınan örneklerde çinko (Zn), bakır (Cu), kadmiyum (Cd), kurşun (Pb) ve arsenik (As) metallerinin birikimleri incelenmiştir. Pb ve Cd metallerinin analizlerinde Grafit Atomik Absorpsiyon Spektrometresi (GFAAS) kullanılmıştır. Cu ve Zn analizleri Fast Sequential Atomik Absorbsiyon Spektrometresi (FSAAS), As analizi ise Hidrür Sistemli Atomik Absorbsiyon Spektrometresi (HSAAS) kullanılarak gerçekleştirilmiştir. Zn, Cu, Cd, Pb ve As aralıkları sırasıyla 97,55-391,59 ppm; 32,92-56,63 ppm; 0,20-2,72 ppm; 8,08-44,98 ve 17,05-54,35 ppm’ dir. Birikimin kaynağının anlaşılabilmesi için alandan temin edilen toprak ve su örneklerinde de metal seviyeleri ölçülmüştür. Kemik/toprak oranları ve maden yataklarına yakınlık durumları göz önüne alındığında Adramytteion iskelet serisinde tespit edilen yüksek metal birikimleri, diyagenetik etkinin belirleyici bir faktör olduğunu düşündürtmektedir. Bununla birlikte su örneklerinin, kemikteki metal birikimlerine etkisinin bulunmadığı saptanmıştır. Özellikle Cu sonuçları incelendiğinde, metal/toprak oranının aşırı yüksek değerler göstermesinin altında yatan sebeplerin, ancak bu toplumun yaşam biçimi üzerine daha fazla sayıda çalışma yapılması ile aydınlatılabileceği sonucuna ulaşılmıştır.
