Abstract:
Abstract Limited data are available about the accumulation of heavy metals in cave fish. In current
study, eight species of fish in six caves were selected and the heavy metal contents of Cr, As, Cd,
Pb, Zn, Cu, Ni, and Hg. The results showed the average concentration of these metals in the order
Zn > Cu > Cr > Ni > Cd > As > Pb > Hg. The bio-concentration factors of Cu, Zn, Cd, and
Pb were greater than 5000. The outcome of the health risk assessment suggests that consumption of
the viscera or gills of cave fish from the karst caves in Libo can pose considerable health risks.
