“…The Commission has changed the recommended value for the standard atomic weight of cadmium, A r (Cd), to 112.414(4) from 112.411(8) based on an evaluation published by Pritzkow et al [45]. While the majority of atomic-weight determinations of multi-isotopic elements employ a single gravimetrically prepared mixture of two near-pure isotopes, this work is a tour de force of seven near-pure isotopes of cadmium (cadmium has a total of eight stable isotopes).…”

“…Further, stable isotopes of these elements may somehow fall into both groups: traditional as well as non-traditional stable isotopes, depending on the isotopes of interest and the ratios being calculated. The natural variation of the 87 Sr/ 86 Sr isotope ratio, as a result of the radioactive decay of 87 Rb, has been used for decades in geochronology and can -in good conscience -be considered as a traditional isotope ratio. In contrast to that the other three naturally occurring isotopes 84 Sr, 86 Sr and 88 Sr have been taken as invariant in nature until the early 2000s when first papers about an observed variation were published.…”

“…Industrial Cd emissions are prone to processes that involve evaporation and condensation, which induce significant fractionation effects (< 1 ‰ for 114 Cd/ 110 Cd), thus providing potential signatures to trace human sources of Cd in the environment [32]. The extent of isotopic fractionation of Cd is rather low compared to the traditional systems, not significantly exceeding the range from -3.6 ‰ to +3.4 ‰ in terrestrial materials [87]. So far, the largest Cd isotope fractionations were determined in oceanic environments (up to 4 ‰ for 114 Cd/ 110 Cd) and attributed to biological uptake and utilization of dissolved seawater Cd [88].…”

Analytical ecogeochemistry is an evolving scientific field dedicated to the development of analytical methods and tools and their application to ecological questions. Traditional stable isotopic systems have been widely explored and have undergone continuous development during the last century.The variations of the isotopic composition of light elements (H, O, N, C and S) have provided the foundation of stable isotope analysis followed by the analysis of traditional geochemical isotope tracers (e.g. Pb, Sr, Nd, Hf). Questions in a considerable diversity of scientific fields have been addressed, many of which can be assigned to the field of ecogeochemistry. Over the past fifteen years, other stable isotopes (e.g. Li, Zn, Cu, Cl) have emerged gradually as novel tools for the investigation of scientific topics that arise in ecosystem research and have enabled novel discoveries and explorations. These systems are often referred to as non-traditional isotopes.The small isotopic differences of interest that are increasingly being addressed for a growing number of isotopic systems represent a challenge to the analytical scientist and push the limits of today's instruments constantly. This underlines the importance of a metrologically sound concept of analytical protocols and procedures and a solid foundation of data processing strategies and uncertainty considerations before these small isotopic variations can be interpreted in the context of applied ecosystem research. This review focuses on the development of isotope research in ecogeochemistry, the requirements for successful detection of small isotopic shifts as well as highlights the most recent and innovative applications in the field.

“…Most of these local laboratory materials are not available as a general resource internationally. Pritzkow et al [266] prepared and characterized a material named Cd-2211, which they suggested as the zero-delta material, but which is not yet commercially available. On this scale, the BAM-I012 material (named Cd-I012 herein) is listed with δ…”

Abstract:Since the early 1950s, the number of international measurement standards for anchoring stable isotope delta scales has mushroomed from 3 to more than 30, expanding to more than 25 chemical elements. With the development of new instrumentation, along with new and improved measurement procedures for studying naturally occurring isotopic abundance variations in natural and technical samples, the number of internationally distributed, secondary isotopic reference materials with a specified delta value has blossomed in the last six decades to more than 150 materials. More than half of these isotopic reference materials were produced for isotope-delta measurements of seven elements: H, Li, B, C, N, O, and S. The number of isotopic reference materials for other, heavier elements has grown considerably over the last decade. Nevertheless, even primary international measurement standards for isotope-delta measurements are still needed for some elements, including Mg, Fe, Te, Sb, Mo, and Ge. It is recommended that authors publish the delta values of internationally distributed, secondary isotopic reference materials that were used for anchoring their measurement results to the respective primary stable isotope scale.
