The presented investigations aimed at determining manganese status in the European bison free ranging in Białowieża primeval forest on the basis of the analysis of some chosen tissues and organs, considering the sex and age of the animals. The manganese status in the liver, kidneys, gastrocnemius muscle, hair, and hoof was determined. The material for analyses was obtained in the winter 2002 from animals eliminated within annual selection. The material originated from 20 European bisons aged from 5 months to 5 years. Animals were grouped according to sex and age (calves up to one year of age, animals aged over two years). The manganese content (except hoof) was determined using the ICP- OES method in the accredited laboratory. In the hoof samples the content of manganese was determined using the method ICP - MS in the same laboratory. The obtained results were analysed statistically with the Statistica programme. No statistically significant differences in the manganese content were observed depending on the sex and age of animals. The mean manganese content in the tissues and organs (n=20; mg·kg⁻¹ of fresh tissue) was as follows: liver - 10 ±1.2; kidneys - 4.5 ±1.2; ribs - below the sensitivity of the apparatus (<1 ppm of Mn in the solution); muscle - 2.3 ±0.4; hair - 15.2 ±4.3; hoof-3.0 ±2.2 (in dry matter).
