Megjegyzések:	The aim of our study was to analyze the effects of thermal spring on elemental concentrations on frog toe bones in the Balkan frog (Pelophylax kurtmuelleri). There were collected 60 adult frogs from five thermal spring and one control pond (10 specimens from each pond) in southern Albania in 2011. The control pond was about 20 km from the thermal springs. Weights and body length of each frog were measured. The following elements were analysed in toe bones Ba, Ca, Mg, P, S, Sr and Zn, respectively. Our results showed that significantly smaller frogs were found in the thermal spring than in the control pond, expect one thermal spring. Principal component analysis (PCA) showed a weak separation of thermal springs and control pond based on the elemental concentration of frog toe bones. Higher Ca and P concentrations were found in frogs from the control pond than in frogs which were collected from thermal springs. In the cases of other elements such as Fe, S and Ba the highest concentration was in frogs from thermal spring. Our results indicated that the bioaccumulation potential was high for frogs from the sediment, because of strong correlation was found between elemental concentration of sediment and toe bones (R2=0.792). While, weakly interaction was between elemental concentration of thermal spring and river water and toe bones (thermal =0.393, river: R2=0.180). In summary, the analysis of toe bones demonstrated that spring: R2 thermal springs may have effects of frog morphology size and elemental concentration of toe bones, and bones are useful to assess the environmental load and the quality of aquatic environment.
