No full textProblems associated with mining are the disposal
of wastes on tailing disposal facilities (TDFs). The
aim of this study was to determine the ecotoxicity of
gold mine tailings by using earthworm bioassays, earthworm
biomarkers and enzymatic analyses. End points
included changes in biomass, reproduction, lysosomal
membrane stability, tissue metal concentrations, and
selected enzymatic activities. Results indicated high
concentrations of Ni in the material as well as bioaccumulation
of lead and arsenic in the earthworm body
tissue after exposure. Enzymatic activity was higher in
revegetated tailings than in unrehabilitated tailings. It
was concluded that TDF and surrounding areas have an
acidic pH which affects earthworms and metal bioavailability.
Soil enzymatic activities were a sensitive indicator
of metal pollution in mining areas. Growth, reproduction
and lysosomal membrane stability of earthworms
have also been shown to be sensitive end points
