Determination of trace elements Cd, Co, Mo, Se, Ti and V in natural waters by neutron activation analysis

Although the water chemistry in saline lakes can differ drastically due to subtle differences in inflowing water conditions, the concentrations, distributions, and geochemical behaviors of trace elements in such environments are poorly understood. In this study, the influence of major‐ion chemistry on the trace element distribution in saline lakes is examined based on major and trace element concentrations and geochemical modeling in three carbonate‐rich saline lakes located in Mongolia and Turkey. The results are compared to data reported from other carbonate‐rich and carbonate‐depleted lakes. The concentrations of U and oxyanions (V, Mo, and W) in carbonate‐rich saline lakes are several orders of magnitude higher than their contributing rivers and seawater. By contrast, their concentrations in carbonate‐depleted saline lakes are lower than those in rivers and oceans. The high U concentrations in carbonate‐rich saline lakes are possibly attributed to the formation of (magnesium–)uranyl–carbonate complexes, and the high oxyanion concentrations are likely a result of the high pH of lake water preventing them from being adsorbed onto solid phases such as suspended particulate matter and sediment. Strontium and Ba concentrations are lower in carbonate‐rich saline lakes than in river water and seawater, but relatively higher in carbonate‐depleted lakes. Incorporation into aragonite and/or calcite, adsorption onto solid phases, and formation of carbonate minerals are possible mechanisms that may account for the lower concentrations of these elements in carbonate‐rich lakes. These results help elucidate the influence of water chemistry on trace element distribution in saline lakes.

12Concentrations of 23 elements (Be, Al, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, 13Se, Rb, Sr, Mo, Pd, Cd, Sn, Pt, Pb) were evaluated in whole blood samples of live 14 harbor seals (Phoca vitulina) from two different locations in the Wadden Sea, the 15 Lorenzenplate in Germany, and the Danish island RØmØ. Elemental blood levels 16 were compared to data from literature of seals, other marine mammals and humans. 17While homeostatically controlled elements showed no differences, concentrations of 18As, Cr, Mn, Mo, Se, and V were higher than human levels. Furthermore, animals 19 from both locations showed significant geographical differences in whole blood 20 concentrations of Al, Mn, Cu, and Pt. These findings could be explained by 21 differences in feeding areas. The element pattern was not affected by gender. In 22 conclusion, these findings indicate an impact of the environment on biochemical 23 blood parameters of the harbor seals. The significant differences of elements in blood 24 samples of two groups of seals, which were associated with geographical variations 25 2 of prey support the use of element pattern in blood as tool for investigation of 1 environmental impact on seals. 2 3
