Aims: Accumulation of trace elements occurs in conditions of decreased or termination of kidneys functions. In some conditions increased trace elements can obtain toxic features. On other hand, researches are showing that concentration of some trace elements could be decreased in ERSD patients, too. The most important factor affecting trace element concentration in ERSD patient is the degree of renal failure and using of replacement therapy. Materials and methods: We determined the concentration of microelements (beryllium, boron, aluminum, vanadium, chromium, nickel, arsenic, rubidium, strontium, cadmium, cesium, barium, thallium and lead) in whole blood of 41 ESRD patients with chronic kidney disease stage VD, who were treated with hemodialysis / hemodiafiltration and in 61 conditionally healthy donors. Determination of whole bloods trace elements content was conducted using inductive coupled plasma mass- spectrometry (ICPMS).  Results: It is determinate that levels of beryllium, boron, aluminum, vanadium, chromium, strontium, cadmium, barium, thallium and lead is reliable increased in ESRD patients. Decreased levels are observed for nickel, arsenic, cesium and rubidium. Conclusions: ESRD is accompanied with substantial and multidirectional changes of trace elements blood levels. During researches has shown that in ESRD patients processes of trace elements accumulation are prevailing over elimination ones.

Abstract. Barium (Ba) incorporated in the calcite of many foraminiferal species is proportional to the concentration of Ba in seawater. Since the open ocean concentration of Ba closely follows seawater alkalinity, foraminiferal Ba/Ca can be used to reconstruct the latter. Alternatively, Ba/Ca from foraminiferal shells can also be used to reconstruct salinity in coastal settings where seawater Ba concentration corresponds to salinity as rivers contain much more Ba than seawater. Incorporation of a number of minor and trace elements is known to vary (greatly) between foraminiferal species and application of element/Ca ratios thus requires the use of species-specific calibrations. Here we show that calcite Ba/Ca correlates positively and linearly with seawater Ba/Ca in cultured specimens of two species of benthic foraminifera, Heterostegina depressa and Amphistegina lessonii. The slopes of the regression, however, vary 2–3 fold between these two species (0.33 and 0.78, respectively). This difference in Ba-partitioning resembles the difference in partitioning of other elements (Mg, Sr, B, Li and Na) in these foraminiferal taxa. A general trend across element partitioning for different species is described, which may help developing new applications of trace elements in foraminiferal calcite in reconstructing past seawater chemistry.
