TLDR
Investigation of the bioaccumulation of metals, as well as relevant biomarkers, in C. gariepinus specimens sampled from the Wonderfontein Cave found that metals associated with acid mine drainage were significantly higher in the population and were reflected in an increase in oxidative stress biomarkers and the induction of metallothionein, a biomarker of metal exposure.
