Abstract
Environmental pollution results in serious health hazards to animals, reflected in biogenic and risk element concentrations in animal tissues. The objective of this study was to examinate concentration of selected elements in testes, and epididymal spermatozoa motility of wild boars. Wild boars were hunted in region Žuhračka - Levice, Slovak Republic. Testes were removed postmortem, spermatozoa were collected from cauda epididymis and assessed by CASA system. Elements concentrations were measured by ICP and by CV-AAS. Spermatozoa motility was 44.29% and progressive motility 18.47%. Concentration of elements in testes was in following order: K > Na > Mg > Ca > Fe > Zn > Al > Cu > Se > Mn > As > Cr > Pb > Mo > Sr > Ni > Ba > Cd > Li > Hg. The most notable correlations indicate association between Se and total spermatozoa motility, as well as with progressive motility, furthermore between As and velocity curved line and beat cross frequency. A high positive significant correlation was found between mercury and beat cross frequency. The data may serve as a fine control indicator to detect potentially toxic elements accumulated from polluted environment that can affect reproduction of wild animals.
