“…The concentrations of the acute phase protein CRP were high or in the upper range compared to reference date described for harbor seals [30]. The Hp concentrations were distinctly elevated for four of five seals (Pv 01, 03, 04, 05) compared to the reference range of harbor seals [19]. The Tf concentrations were elevated for all five seals and the CDT ratio for Pv 01 compared to published reference ranges determined for wildlife harbor seals of the German North Sea [22].…”

Helgoland and Sylt are important centers of tourism in the North Sea. Harbor and grey seals are one reason for the attraction of these islands. However, little is known about these local seal groups. The present postmortem health and pollution study describes a multiparameter investigation of five ill harbor seals which were shot for animal welfare reasons. Firstly, results of pathology and blood investigations support the bad prognosis of survival made in the field. Signs of inflammation in organs, malnutrition, a high-stress level, and reduced thyroid activity were found. Secondly, metal and organic contaminants were investigated. Metal pollutants in blood, liver, muscle, and kidney tissue were not elevated. Lead and mercury concentrations showed a decreased level compared to former studies. Additionally, interesting insights were found for several organic contaminants in comparison with other studies. The Helgoland seals may be influenced by the contaminants of the Elbe plume.

“…Although these activities include seals from the islands Sylt and Helgoland, the locations are not considered separately, and little is known about the local groups of these islands. In a previous study, we published data on the health parameter haptoglobin measured in plasma of seals (Phoca vitulina) from Helgoland [19].…”

“…Median, minimum, and maximum element concentrations were compared between seals of the islands Anholt (Kattegat, Baltic Sea) and Helgoland (North Sea, Germany) with our previous studies on seals from Rømø (Wadden Sea, Denmark), Lorenzenplate (Wadden Sea, Germany), and Elbe estuary (Neuwerk, Germany) (Table 4; Griesel et al 2008, Kakuschke et al 2010a.…”

“…However, only a few health and pollution studies have been realized. In three previous studies, we published acute phase protein blood concentrations of haptoglobin, C-reactive protein, and transferrin from harbor seals (Kakuschke et al 2010a;Grebe et al 2011;Kakuschke et al 2013). Additionally, a postmortem study of seals from Helgoland described macroscopic findings, blood parameters as well as metal and organic contaminants of several body fluids and tissues .…”

“…Blood sampling of harbor seals is considered minimally invasive and allows the analyses of pollutants, biomarkers, and health parameters additionally to in vitro cell experiments from living animals. For the North Sea, several investigations have been performed to measure contaminants (Griesel et al 2006;Das et al 2008;Griesel et al 2008;Kakuschke et al 2009;Weijs et al 2009a, b, c;Kakuschke et al 2010b), assess immune cell functions (De Swart 1995;Ross 1995;Kakuschke et al 2005;Das et al 2008;Dupont et al 2013), or analyse biomarkers Hasselmeier et al 2008;Kakuschke et al 2010a;Grebe et al 2010Grebe et al , 2011Grebe et al , 2012Kakuschke et al 2013) in blood samples of harbor seals. Most of these studies focused on animals closed to urbanized areas along the Wadden Sea coast.…”

The harbor seals (Phoca vitulina) from Helgoland (North Sea) and Anholt (Kattegat, Baltic Sea) are top predators within the marine food web and an indicator species of the environmental contamination. Furthermore, they are a main tourist attraction. Despite these important roles, little is known about the health and pollutant contamination of these seals. The objective of this study was therefore to investigate 18 essential and nonessential/toxic elements (Al, As, Be, Ca, Cr, Cu, Fe, K, Mn, Mo, Ni, P, Pb, Rb, S, Se, Sr, and Zn) in blood samples using inductively coupled plasma mass spectrometry and total X-ray-fluorescence spectrometry. Blood concentrations of mineral nutrients, such as Ca, K, P, and S, were within the reference ranges described for harbor seals. Likewise, for the trace elements, As, Be, Rb, Se, and Sr, no significant differences were observed compared with previous studies. Interestingly, blood concentrations of nine nonessential as well as essential trace metals (Al, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Zn) measured significantly lower in the offshore living seals from Helgoland and Anholt compared with results obtained from animals living close to urbanized areas, such as the Wadden Sea and Elbe estuary. This suggests that industrial emissions, sewage deposition, shipping traffic and dredging tasks might be the cause of increased metal concentrations of inshore harbor seals.
