Potential harmful elements in fossorial water voles inhabiting non-polluted crops

This dataset contains biological and contaminant-related measurements from Arvicola scherman individuals collected in non-polluted habitats. For each specimen, data include indicators of body condition, body mass and body length, as well as concentrations of four trace elements—cadmium (Cd), lead (Pb), mercury (Hg), and selenium (Se)—measured in three tissue types: kidney, liver, and muscle. The dataset is suitable for studies on small-mammal ecotoxicology, trace-element bioaccumulation, and the relationship between body condition and contaminant load in wildlife from clean environments.
