Abstract
Pollution of the environment can be determined with the help of bioindicators – organisms which enable assessment of the quality of their environment. Due to their characteristics (high bioaccumulation of different pollutants; yearly regrowth enables high self-standardisation; availability of historical samples in well-dated trophy collections), roe deer antlers are a perfect tool for spatial as well as temporal bioindication in either accumulative (contents of pollutants in antlers reflect their burdens in the environment) or reactive (fluctuating asymmetry is a good indicator of stressful factors, including pollution) sense. Therefore, measurements of heavy metals (Pb, Cd, Zn), fluoride and sulphur levels in historical samples of roe deer antlers, shot in the Šalek Valley, the Upper Meža Valley (two areas with high emissions from electricity generating and smelting plants) and in the woody region around Notranjski Snežnik (a control area) would enable assessment of historical changes in pollution of the environment in last fifty years. Moreover, the analysis of stable Pb isotope ratio may allowed us to determine the most important emission sources in the specific period of time. Consequently, the efficiency of sanation measures on big local emission sources in northern Slovenia will be enabled as well. Measurement of fluctuating asymmetry (non-directional differences between left and right beam of bilateral roe deer antlers, which were caused by different stressors, such as pollutants) running parallel would reflect the biological effect of pollution on roe deer (conservative value of the research project). Combination of both accumulative and reactive approach would enable a development of new bioindication method with general employability, simplicity, rapidity and low costs as the main advantages. Since the assessment of efficiency of sanation measures will be enabled and the most important sources of pollution in space and time may be determined, the research project has a definite application value.
