Content and character of metal accumulation in fish of the Kichera River (a tributary of Lake Baikal)

A study of metal accumulation in fish from the Kichera River, a tributary of Lake Baikal, reveals that metals such as manganese (Mn), zinc (Zn), lead (Pb), cadmium (Cd), cobalt (Co), and mercury (Hg) are present in varying concentrations in muscle tissue and liver across different trophic levels. The research highlights significant differences in metal accumulation patterns between these tissues, with liver showing higher concentrations of certain metals like Cd and Hg compared to muscle tissue. This suggests a potential bioaccumulation risk for predator species higher up the food chain. The study employed chemical analysis to quantify metal content, providing critical insights into environmental contamination levels in this ecologically significant region.
