Introduction and objective:
The study deals with the accumulation of iron (Fe), copper (Cu), and zinc (Zn) in the organs (kidney, liver, and muscle) of wild boar from four districts of Slovakia with different levels of industrial activity, mining, and agriculture, while also evaluating the concentrations of these trace elements in different age and sex categories of the animals.

Material and methods:
Samples of internal organs and muscle were collected from game (n=147) hunted during individual or group hunts on State or private hunting grounds in the regions of Rimavská Sobota, Revúca, Rožňava, and Košice, located in the southern part of central and eastern Slovakia.

Results:
Mean kidney Fe concentration varied from 72.65–115.3 mg · kg ^-1 w.w. Hepatic Fe levels fluctuated from 206.5–288.7 mg · kg ^-1 w.w., and the amount of Fe in muscle tissue ranged from 42.44–70.03 mg · kg ^-1 w.w. Renal Cu values were 3.81–5.24 mg · kg ^-1 w.w., liver Cu values 2.80–3.65 mg · kg ^-1 w.w., and muscle tissue Cu values were 1.52–2.47 mg · kg ^-1 w.w. Mean contents of Zn in kidney moved within the range 27.54–30.72 mg · kg ^-1 w.w., in liver 37.36–42.84 mg · kg ^-1 w.w., and in muscle tissue 28.10–36.06 mg · kg ^-1 w.w. Concentrations of the given elements in different age groups were compared, where these values increased proportionally with age. No significant differences were found between genders.

Conclusions:
Based on the obtained results, the presence of the given trace elements in the environment in the counties of central and eastern Slovakia varies significantly, with the highest probability attributable to the mining of industrial minerals and the varying intensities of industrial development in the surveyed areas.
