In this thesis the concentrations of heavy metals have been statistically appraised on the basis of samples gained from small intestines of European hare - Lepus europaeus and from an endoparasite Trichuris leporis (found by a washing method). Tha appraisal has been performed by atomic absorption spectrometry -- AAS, electrothermal atomization - ETA-AAS (for Cd, Cr, Ni, Pb), and means of atomization in the flame FAAS (Cu, Mn, Zn). The pieces of offal of hare game have been obtained from a common hunting in the localities of the Czech Republic represented by the region of South Moravia, Moravian-Silesian, Olomouc, and the Highlands. The sample collecting has been conducted from 2008 to 2012. Statistically significant differences of heavy metals concentrations have been found out between the individual localities. In addition, an endoparasite as a possible bioindicator of heavy metals load on the forest environment has been evaluated differently. Furthermore, in endoparasites there have been detected an exceeding of the hygiene limits for food. Conclusion made on the basis of all statistical analysis performed in this study says that Trichuris leporis indicates heavy metals load on ecosystems by wider range of heavy metals than the small intestine and more, considerably in the higher concentrations. Thus, Trichuris leporis can be used as a sentinel organism for the indication of heavy metals in the forest environment, at least in an area of the European hare territory.
