This study examines the hypothesis that bromine in human skeletal tissue serves as an indicator of marine diet. Synchrotron‐based X‐ray fluorescence microscopy of samples from archaeological sites on the Peruvian North Coast showed relative enrichment of bromine in the cementum and osteons. X‐ray absorption spectroscopy determined organobromine to be present, suggesting an exclusive association with the organic component. We used skeletal tissue from marine mammals as a proxy for the marine diet. Bromine, when observed in these specimens, was recorded close to the detection limits; therefore, bromine in archaeological skeletal material does not appear to be an indicator of marine diet.

溴，可能是海洋饮食指标吗？重新假设

这项研究检验了以下假设：人体骨骼组织中的溴可作为海洋饮食的指标。来自秘鲁北海岸考古现场样品的基于同步加速器的X射线荧光显微镜观察表明，牙骨质和骨质中的溴含量相对较高。X射线吸收光谱法确定存在有机溴，表明与有机成分存在排他性关联。我们使用来自海洋哺乳动物的骨骼组织作为海洋饮食的替代物。在这些样品中观察到溴时，记录的溴含量接近检测极限。因此，考古骨骼材料中的溴似乎不是海洋饮食的指标。
