Ecotoxicological research detailing trace metal contamination and seasonal variation in the tissues of northern fishes such as Arctic charr (Salvelinus alpinus) has been poorly represented in the literature beyond examination of mercury. In an effort to address this, anadromous Arctic charr were collected from the Deception River watershed in the late summer and post-winter season, before quantifying seasonal and organotropic variations in dorsal muscle and liver concentrations of arsenic, cadmium, chromium, copper, nickel, lead, and zinc. Potential linkages with biological variables (fork length, age, and somatic condition) and indicators of feeding behavior (δ¹³C and δ¹⁵N) were also assessed. Trace metal organotropism favouring elevation in liver tissue concentrations was exhibited by cadmium, copper, nickel and zinc, while arsenic, chromium and lead exhibited no significant organotropic variation. Seasonal differences in concentrations were metal and tissue dependent, but generally increased in tissues collected from post-winter sampled Arctic charr. Significant correlations with biological and trophic descriptors were also determined to be element and tissue dependent. These parameters, in addition to season, were incorporated into multi-predictor variable models, where variations in trace metal concentration data were often best explained when season, somatic condition, and trophic descriptors were included. These variables were also of greatest relative importance across all considered trace metals and tissue types. These findings suggest that seasonally linked processes have the greatest influence on trace metal concentrations in anadromous Arctic charr. Future metal-related research on Arctic charr and other northern fish species should further consider these variables when evaluating elemental accumulation.

详细的生态毒理学研究详细介绍了诸如鲑鱼（Salvelinus alpinus）之类的北方鱼类组织中的痕量金属污染和季节性变化，但文献中对汞的研究却很少。为了解决这个问题，在定量分析砷，镉，铬，铜，镍，铅和锌。与生物变量（叉长度，年龄，和身体条件）和指标摄食行为的（潜在联系δ ¹³ C和δ ¹⁵N）也被评估。镉，铜，镍和锌表现出有利于肝脏组织浓度升高的微量金属有机质，而砷，铬和铅则无明显的有机质变化。浓度的季节性差异取决于金属和组织，但通常从冬季采样后的北极炭收集的组织中有所增加。还确定与生物学和营养描述子的显着相关性是元素和组织依赖性的。这些参数，除季节外，还被合并到多预测变量模型中，其中，当包括季节，体况和营养描述时，通常可以最好地解释痕量金属浓度数据的变化。这些变量在所有考虑的痕量金属和组织类型中也具有最大的相对重要性。这些发现表明，季节性链接的过程对北极北极红藻中痕量金属的浓度影响最大。在评估元素积累时，未来有关北极红点鲑和其他北部鱼类的金属相关研究应进一步考虑这些变量。
