“…Notably, published Cd isotope data for birch leaves 13 and Cd-tolerant plants 14 exhibit a similar range of δ 114/110 Cd values (from -0.39 to 1.3‰) as were measured here for the plant parts (-0.12 to 0.97‰).…”

18Analyses of stable metal isotope ratios constitute a novel tool to improve understanding of 19 biogeochemical processes in soil-plant systems. In this study, we used such measurements 20 to assess Cd uptake and transport in wheat grown on three agricultural soils under 21 controlled conditions. Isotope ratios of Cd were determined in the bulk C and A horizons, in 22 the Ca(NO 3 ) 2 extractable Cd soil pool and in roots, straw and grains. The Ca(NO 3 ) 2 23 extractable Cd was isotopically heavier than the Cd in the bulk A horizon (Δ

“…13,14 Cadmium is also known to sorb to the negatively 57 charged surfaces of the root apoplast [15][16][17] where it can also precipitate with phosphates. 18 In 58 the soil solution and in several plant parts, Cd is furthermore complexed by inorganic and 59 organic ligands.…”

“…However, batch number must be indicated when SPEX Cd is reported in different laboratories, because of the large difference in δ 114/110 Cd NIST SRM 3108 values obtained in different batches, for example δ 114/110 Cd NIST SRM 3108 of Spex‐1 are −0.09 ± 0.01 ‰ for Lot: 74‐075219K and −1.25 ± 0.06‰ for Lot: CL6‐30CDY relative to NIST SRM 3108 (Wei et al . , ). BAM I012 yielded a δ 114/110 Cd NIST SRM 3108 value of −1.31 ± 0.09‰ (2 s , n = 13) and a δ 112/110 Cd NIST SRM 3108 value of −0.66 ± 0.08‰ (2 s , n = 13), which is indistinguishable from value reported by previous studies (Abouchami et al .…”

We report high‐precision cadmium isotope ratios for a series of standard solutions and geological reference materials for interlaboratory comparison. Complete separation of Cd from a matrix in geological samples was achieved using AG MP‐1M anion exchange resin with > 97.8% recovery. Cadmium isotope ratios were measured by both Neptune plus multi‐collector‐inductively coupled plasma‐mass spectrometry (MC‐ICP‐MS) and Nu Plasma II MC‐ICP‐MS at low‐resolution mode. Both sample calibrator bracketing (SSB) and double‐spike techniques (DS) were utilised for mass bias correction. Cadmium isotope ratio data of standard solutions (BAM I012 Cd, SPEX Cd, Alfa Aesar Cd, GSB Cd) and geological reference materials (GSS‐1, GXR‐1, GXR‐2, GSD‐12, NIST SRM 2711a) are reported relative to Cd solution (NIST SRM 3108). The intermediate precision over a three‐year period was better than ± 0.09‰ (2s) for δ114Cd/110Cd and ± 0.06‰ (2s) for δ112Cd/110Cd ratios. SPEX Cd was used as a secondary reference material for Cd isotopic measurement with a δ114/110CdNIST SRM 3108 value of −2.13 ± 0.09‰ (2s). The soil reference material NIST SRM 2711a has a significantly heavier isotopic composition than other soil materials, GXR‐1, GXR‐2 and GSS‐1. New recommended values are presented for future interlaboratory calibration.

“…Cadmium isotopes have also been used to investigate ore deposit formation processes (e.g., Zhu et al , Wen et al , Zhu et al ) and marine cycling of Cd (e.g., Lacan et al , Ripperger et al , Abouchami et al , Conway and John ). In recent decades, Cd mass fractions in world‐wide soils have dramatically increased due to contamination from mining, smelting, electroplating, wastewater irrigation, and use of chemical fertilisers and pesticides (e.g., Ghosh and Singh , Zhang et al , Wei et al ). Previous studies have found that polluted materials have different Cd isotope compositions and, therefore, Cd isotopes can be used to trace sources of contamination (e.g., Cloquet et al , Gao et al , Pallavicini et al , Wen et al , Imseng et al ).…”

This study presents a high‐precision Cd isotope measurement method for soil and rock reference materials using MC‐ICP‐MS with double spike correction. The effects of molecular interferences (e.g., 109Ag1H+, 94Zr16O+, 94Mo16O+ and 70Zn40Ar+) and isobaric interferences (e.g., Pd, In and Sn) to Cd isotope measurements were quantitatively evaluated. When the measured solution has Ag/Cd ≤ 5, Zn/Cd ≤ 0.02, Mo/Cd ≤ 0.4, Zr/Cd ≤ 0.001, Pd/Cd ≤ 5 × 10−5 and In/Cd ≤ 10−3, the measured Cd isotope data were not significantly affected. The intermediate measurement precision of pure Cd solutions (BAM I012 Cd, Münster Cd and AAS Cd) was better than ± 0.05‰ (2s) for δ114/110Cd. The δ114/110Cd values of soil reference materials (NIST SRM 2709, 2709a, 2710, 2710a, 2711, 2711a and GSS‐1) relative to NIST SRM 3108 were in the range of −0.251 to 0.632‰, the δ114/110Cd values of rock reference materials (BCR‐2, BIR‐1, BHVO‐2, W‐2, AGV‐2, GSP‐2 and COQ‐1) varied from −0.196‰ to 0.098‰, and that of the manganese nodule (NOD‐P‐1) was 0.163 ± 0.040‰ (2s, n = 8). The large variation in Cd isotopes in soils and igneous rocks indicates that they can be more widely used to study magmatic and supergene processes.
