o:8550 Assessment of Mercury contamination in liver and muscle tissue of mallards (Anas platyrhynchos) as bioindicators at three locations in Serbia en The aim of this study was to investigate the presence and distribution of mercury (Hg) in the liver and muscle tissue of Mallards (Anas platyrhynchos) collected from three loca‑ tions in Serbia. A total of 55 samples were analyzed, including 23 from the Belegiš site, 12 from Pločica, and 20 from Vršački Ritovi. Mercury concentrations were determined us‑ ing the ICP‑MS method. Mercury levels in the liver ranged from 0.009 to 0.239 mg kg −1 , while concentrations in muscle tissue ranged from 0.005 to 0.069 mg kg −1 . The mean val‑ ues for liver tissue were 0.097 mg/kg (Belegiš), 0.108 mg/kg (Pločica), and 0.025 mg kg −1 (Vršački Ritovi), whereas for muscle tissue they were 0.030 mg kg −1 (Belegiš and Pločica) and 0.008 mg kg −1 (Vršački Ritovi). Statistical analysis included descriptive statistics, Pearson correlation test, analysis of variance (ANOVA) with Tukey post hoc test, Levene’s test for homogeneity of variances, Kruskal–Wallis test, and Mann–Whitney test. The find‑ ings provide insight into potential differences in mercury contamination levels between different ecosystems, as well as the relationship between different tissues in wild birds.
