The two red cultivars showed significantly higher concentrations of Cu, Cr, Ba, Mo, Cd, Ga, Ge, and Tl and lower concentrations of B, Mn, Sr, and U than the white cultivar Italian Riesling. However, the tissue distribution of rare earth elements was totally different from that of the ...
5a, b) to calculate Sm/Nd and Lu/Hf. We further calculated all trace element abundances in the evolving LMO along a fractionation sequence of Schmidt and Kraettli (2022) for elements with reliable trace element partition coefficients, determined in this study (Li, Ba, Th, U, Sc, Ti, V,...

The distributions and concentrations of trace elements in the environment exposed to biological materials including humans can affect life depending on the exposure and degree of concentrations. Whilst the essential trace elements impacts on human development the potential toxic elements will have adverse ...
Background: Since the introduction of long-term parenteral nutrition (PN), morbidity due to inadequate replacement or toxicity of routinely administered trace elements has been well described. After decades of experience, much debate still exists about optimal supplementation. In practice, trace elements...
Trace element abundances in igneous zircons, as determined by electron microprobe and laser-ablation microprobe ICPMS analysis, are shown to be sensitive to source rock type and crystallisation environment. The concentrations of 26 trace elements have been determined for zircons from a wide range of ...
Due to the lower concentration of Ca in rapidly cooled clinopyroxenes, divalent large ion lithophile elements (LILE) on M2 decrease at the expense of monovalent cations. Conversely, higher concentrations of HFSE and TE on the M1 site are facilitated as the average charge on this site ...
Clinical trace element deficiencies or toxicities in the dromedary or Bactrian camel are rarely attested. Thereby, references are few, and until recently, standards were rather not defined. Regarding those elements, the characteristics of camel are the i
