- Rare Earth Elements (REEs), La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc, and Y, & two actinides, Th and U were assessed in muscle and liver tissues of wild, backyard and commercially raised rabbits through ICP-MS. Higher concentrations were found in liver in comparison to muscle tissue. Liver of wild rabbits accumulates all studied elements beyond Tm. Backyard rabbits do not show any statistically significant accumulation while commercial accumulate all beyond La, Ce, Pr, Nd, Gd and Tb. Wild rabbits were with the highest amounts for most of these elements. The different living and rearing environments of wild, backyard and commercial rabbits may affect accumulation, fate and transfer of REEs in rabbits' tissues. A dataset for establishing reference values of REEs in Lemnos island wild rabbits' is shown and the literature gap on safety limits for REEs is discussed.
