Cadmium isotope fractionation within the soil profile complicates source identification in relation to Pb–Zn mining and smelting processes

The Cd isotope composition of atmospheric aerosols from the Tropical Atlantic Ocean

“…For leachate subsamples, the EF crust values of the corresponding total digests are plotted. The colored bars denote the Cd isotope compositions of the upper continental crust [ Schmitt et al , ], fumes/ash from metal smelting operations [ Cloquet et al , ; Shiel et al , , Chrastńy et al , ], and ore minerals [ Wombacher et al , ; Shiel et al , ; Zhu et al , , Chrastńy et al ., , Wen et al , , ; Zhu et al , ; Martinková et al , ].…”

“…The observed Cd isotope variations between the products (i.e., ash and slag) and starting materials (i.e., ore minerals and coals) of Pb‐Zn smelting and coal combustion support this hypothesis [ Cloquet et al , ; Shiel et al , ; Martinková et al , ]. Such isotopic variability has been exploited to trace anthropogenic sources of Cd to sediments proximal to Pb‐Zn mining and smelting operations [ Cloquet et al , ; Gao et al , , , Chrastńy et al , , Wen et al , ]. Furthermore, Shiel et al [, ] interpreted Cd isotope data for marine bivalves in the context of anthropogenic and natural Cd sources to coastal waters.…”

Spatial distribution of some trace and major elements in sediments of the Cávado estuary (Esposende, Portugal)

“…The correlation between Ni and Cr was extremely high (0.99), which corroborates their common origin. Similarly, high correlation was also found between the concentrations of Zn and Cd (0.76), probably due to the existence of Cd impurities in Zn ores (Chrastný et al, 2015).…”

Chromatographic Separation of Cd from Plants via Anion-Exchange Resin for an Isotope Determination by Multiple Collector ICP-MS

“…9,10 Cd isotope analyses have been applied in order to investigate the evolution of celestial bodies, [11][12][13] mineral genesis and material source, 7,14 paleo-ocean environments, [15][16][17][18][19] and environmental cadmium pollution sources. 3,4,8,[20][21][22] Furthermore, Wei et al 6 suggested that Cd isotope fractionation in Cd hyperaccumulator plants could apply new insights in the enrichment mechanisms.…”
