“…Measurements for Ca, K, P, and S were within the normal range described for harbor seals (Griesel et al 2006). Despite the small number of animals investigated, the element blood concentrations obtained from Anholt seals were comparable to Helgoland seals (Table 4; Fig.…”

“…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.

The study of liquid biological samples with the use of various techniques has become a routine task nowadays. Saliva has been a study object for the correlation of chemical elements with a disorder in human body. Saliva is an aqueous hypotonic fluid and transparent and produced by various secretory glands (parotid, submandibular, sublingual, and smaller glands). This paper uses the technique of total reflection X‐ray fluorescence (TXRF) to analyze saliva samples collected in duct of the parotid gland and the gingival crevice between first (tooth 46) and second (tooth 47) grinding teeth of seven individuals. Using the TXRF technique, the main objective of this work was to assess the results obtained quali‐quantitatively. The chemical elements identified in saliva samples of the parotid gland and the gingival crevice were P, S, Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Se, Br, Rb, and Pb. Although different elements have been identified in the analyzed samples, the identified chemical elements have varied from one individual to another. Comparing the results obtained from the saliva samples of parotid gland and the gingival crevice, it could be observed in the gingival crevice other elements not found in the parotid gland. Therefore, the sampling strategy and the TXRF technique was able to differentiate chemical elements in the samples of the parotid gland and the gingival crevice.
