The Elbe is one of the major rivers releasing pollutants into the coastal areas of the German North Sea. Its estuary represents the habitat of a small population of harbor seals (Phoca vitulina). Only little is known about the health status and contamination levels of these seals. Therefore, a first-ever seal catch was organized next to the islands of Neuwerk and Scharhörn in the region of the Hamburg Wadden Sea National Park. The investigations included a broad set of health parameters and the analysis of metals and organic pollutants in blood samples. Compared to animals of other Wadden Sea areas, the seals showed higher γ-globulin levels, suggesting higher concentrations of pathogens in this near-urban area, elevated concentrations for several metals in particular for V, Sn, Pb, and Sr, and comparable ranges for chlorinated organic contaminants, except for elevated levels of hexachlorobenzene, which indicates characteristic inputs from the Elbe.
易北河是向德国北海沿海地区排放污染物的主要河流之一。其河口是一小群港湾海豹（Phoca vitulina）的栖息地。这些海豹的健康状况和污染水平知之甚少。因此，在汉堡瓦登海国家公园地区的 Neuwerk 和 Scharhörn 岛屿附近首次组织了海豹捕捞活动。调查包括一系列广泛的健康参数以及血液样本中金属和有机污染物的分析。与其他瓦登海地区的动物相比，这些海豹的γ球蛋白水平较高，这表明在这个近城市地区存在更高浓度的病原体，尤其是 V、Sn、Pb 和 Sr 等几种金属的浓度升高，以及氯化有机污染物的可比范围，除了六氯苯水平升高，这表明易北河的特征输入。
