We investigated the activities of superoxide dismutase (SOD), catalase (CAT), glutathione
peroxidase (GSH-Px), glutathione reductase (GR) and the phase II biotransformation enzyme glutathione
S-transferase (GST) in the whole body of fire salamander larvae (Salamandra salamandra) from two
localities on Mt. Avala (AVS and ABP) and one locality on Mt. Vršački Breg (VSB), Serbia. We also
determined the total glutathione (GSH) and sulfhydryl group (SH) contents, as well as the concentrations of
manganese (Mn), copper (Cu), zinc (Zn), selenium (Se), arsenic (As), cadmium (Cd), lead (Pb) and uranium
(U). The obtained results show that animals from VSB had significantly lower weights and lengths than
animals from AVS and ABP. The activities of all investigated enzymes were significantly higher, while the
SH content was significantly lower in animals from VSB compared to those from AVS and ABP. No
correlations between trace-element concentrations in water and animal tissue were observed. We concluded
that the obtained results were more likely a consequence of the combination of developmental differences
and the effects of different habitat conditions, environmental and anthropogenic influences than of
concentrations of trace elements in the water alone.
