... is affected by external random factors, resulting in a weakened autocorrelation. The IICQ indicates that soil is dominated by mild and moderate pollution, accounting for 42.24 and 44.95%, respectively, with cadmium contributing up to 63.00% to the IICQ. Chromium and cadmium are controlled by natural sources...

Due to the close association of Cd and Sb in hydrothermal systems and the distinct Cd isotopic signatures between magmatic and sedimentary rocks, Cd isotopes have the potential to trace the metal origin in Sb-bearing deposits...

...., USA, and Harvard University, Cambridge, Massachusetts, USA. Cadmium is a rare element, found in average concentration of ∼0.15 ppm in the Earth's crust ( Haynes et al . 2013 ). As such, minerals containing essential Cd are relatively uncommon: only 28 minerals containing Cd, of which 16...
