Levels of lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg) and co- pper (Cu) in the liver, kidney and muscle of 11 individual roe deer (Capre- olus capreolus) were determined. Th e samples were prepared by microwa- ve wet digestion. Content of investigated elements was determined by the method of coupled plasma with mass spectometry. Th e lead concentrations ranged from <0.001 (liver) to 8.455 mg/kg (meat), Cd concentrations ran- ged from 0.004 (muscle) to 0.818 mg/kg (kidney) and As concentrations ranged from 0.002 (liver) to 0.031 mg/kg (kidney). Concentrations of Hg in examined tissues (liver, kidney, muscle) were under limit of detection (<0.001 mg/kg). Th e concentration of copper in liver ranged from 3.913 to 104.08 mg/kg. Th e results of this study showed that no samples excee- ded maximum allowed levels for Cd, Hg, As and Cu. Pb concentrations in muscle samples ranged from 0.008 to 8.455 mg/kg. High concentrations of Pb in two muscle samples are most likely due to the proximity of hunting wound area, as lead was not detected in organ samples. Th e presence of some elements in the tissues of roe deer suggests the necessity of further research aimed at identifying the source of contamination in order to pre- serve the health of both humans and animals.
