6 Life Science, Forensics and Medicine

Freitag, 12:00-13:00, H 36

Stable isotope forensics is a valuable tool for investigating the origin, history, and authenticity of various materials, including food, beverages, drugs, and environmental samples. The analysis of stable isotopes, often combined with other analytical methods, can provide unique information about a sample's geographical origin, manufacturing process, and chemical history. The applications of stable isotope forensics have expanded rapidly in recent years, driven by advances in analytical methods and modeling approaches. This session will focus on recent developments in stable isotope forensics and their applications in various fields, including food authentication, environmental forensics, forensic geology, and doping tests.

We welcome contributions on new analytical methods, case studies, and modeling approaches that advance our understanding of stable isotope forensics and their practical applications.
