ABSTRACT

Isotope analysis has become crucial in forensic anthropology, particularly over the last decade. This method integrates multi-isotope profiles such as C, N, O, H, S, Sr, and Pb, along with isotopic landscapes (\"isoscapes\") from various tissues like teeth, bone, hair, and nails. These analyses predict the potential region-of-origin of unidentified human remains, offering additional evidence for human identification, including birth region, adult residence, travel history, and dietary habits. The principles of isotope analysis involve using natural variations in isotopic ratios to infer geographic origins and behavioral patterns of individuals. Instruments like mass spectrometers are pivotal for precise measurements, ensuring accuracy in data collection. Analytical standards and quality measures are implemented to maintain reliability across analyses. Sample selection is critical, focusing on tissues that best reflect an individual\'s life history and environmental exposure. Future research aims to refine isotope analysis techniques, improve interpretative frameworks, and expand databases of isotopic signatures from diverse populations. This ongoing development underscores the utility of isotope analysis as a dynamic tool in forensic science, continually enhancing its potential to uncover critical information in complex cases of human identification and geographical tracing.
