Elemental content in the tissues of the song thrush Turdus philomelos I. Accumulation of macro- and microminerals in internal organs and tissues
Abstract
The study provides a basic picture of the level of accumulation of metallic elements in the tissues of the song thrush Turdus philomelos. Between 1995 and 2022, thrush carcasses were randomly collected on roads in the High Tatras region (Slovakia). Elements in heart, liver, kidney, pectoral, femoral uscle and femur tissue were analysed by X-ray fluorescence spectrometry from dead individuals. The highest measured values (> 1000 ppm) were found for the elements P, S, Cl, K, Ca and Fe. The trend of accumulation of these elements is approximately the same in internal organs. The content of other elements (Cr, Mn, Cu, Zn, Se, Rb, Mo, Ba, Pb, Hg) was an order of magnitude lower (< 200 ppm) in organs and tissues, and the trend of accumulation in individual organs is variable. We also focused on the correlation between individual elements and tissues. Evaluation in relation to other factors such as gender, location and season will be the subject of an upcoming study.
