Northern pike specimens of 0, 1, and 2 age classes were collected in June 2013 from the Vizelj channel near Belgrade (Serbia). Inductively coupled plasma optical spectrometry (ICP-OES) and atomic absorption spectrometer SpectrAA 220 were used for analyzing concentrations of As, Cr, Cd, Co, Cu, Fe, Sr, Pb, and Zn, as well as Hg in muscle, gills, and liver. Metal pollution index (MPI) was calculated. Concentrations of As, Cd, Co, and Pb were below the limit of detection. Concentrations of Cu, Hg, and Zn in muscle did not exceed the maximum allowed concentrations. The gills were tissue which was most affected by pollution. The highest concentrations of Fe in muscle, Cr and Fe in gills, and Hg, Sr, and Zn in liver were recorded in 0 individuals, as well as Zn in gills of 2 individuals. On contrary, the lowest concentrations were recorded for Zn in gills of 0 individuals, Hg in gills of 1 individuals, and Fe in muscle, Cr and Sr in gills, and Zn in liver of 2 individuals. Regarding age classes, 2 juveniles had the highest MPI values for all tissues. Correlations between the metal(loid) accumulation and fish condition were not significant, as well as between fish length and weight and Cu and Hg in muscle, Cu, Hg, and Sr in gills, and Cu, Cr, and Fe in liver. Results indicated that young individuals were more sensitive to pollution, but older fish showed higher overall bioaccumulation of toxic elements analyzed in this study.
2013 年 6 月，在塞尔维亚贝尔格莱德附近的维泽利（Vizelj）海峡采集了 0、1 和 2 龄级的北方狗鱼标本。使用电感耦合等离子体光学光谱法（ICP-OES）和原子吸收光谱仪 SpectrAA 220 分析肌肉、鳃和肝脏中 As、Cr、Cd、Co、Cu、Fe、Sr、Pb 和 Zn 以及 Hg 的浓度。计算了金属污染指数（MPI）。As、Cd、Co 和 Pb 的浓度低于检测限。肌肉中 Cu、Hg 和 Zn 的浓度未超过最大允许浓度。鳃是受污染影响最大的组织。在 0 龄个体的肌肉中记录到 Fe 的最高浓度，在鳃中记录到 Cr 和 Fe，以及在肝脏中记录到 Hg、Sr 和 Zn 的最高浓度，在 2 龄个体的鳃中记录到 Zn 的最高浓度。相反，在 0 龄个体的鳃中记录到 Zn 的最低浓度，在 1 龄个体的鳃中记录到 Hg 的最低浓度，在肌肉中记录到 Fe、Cr 和 Sr，以及在肝脏中记录到 Zn 的最低浓度在 2 龄个体中。就年龄组而言，所有组织中 2 个幼鱼的 MPI 值最高。金属（类）积累与鱼类状况之间的相关性以及鱼类长度和体重与肌肉中 Cu 和 Hg、鳃中 Cu、Hg 和 Sr 以及肝脏中 Cu、Cr 和 Fe 之间的相关性均不显著。结果表明，幼鱼对污染更敏感，但在本研究中分析的有毒元素的总体生物积累量更高。
