The Occurrence and Incorporation of Copper and Zinc in Hair and Their Potential Role as Bioindicators: A Review

This review from 2007 examined the potential of copper (Cu) and zinc (Zn) concentrations in hair as bioindicators, suggesting that these concentrations were not significantly affected by external factors and could reflect biogenic processes. The study explored how Cu and Zn are incorporated into hair, their associations with specific hair components, and their potential to indicate health disorders, including breast cancer. The research was supported by various international scientific programs and facilities, highlighting the collaborative effort in understanding the role of these metals in hair analysis.
