The number of studies using various stable isotope systems for tracing contamination
sources and various biogeochemical processes is rapidly rising due to the increased …

This work critically reviews stable isotope fractionation of essential (B, Mg, K, Ca, Fe, Ni, Cu,
Zn, Mo), beneficial (Si), and non-essential (Cd, Tl) metals and metalloids in plants. The …

Cadmium (Cd) isotopes have great potential for understanding Cd geochemical cycling in
soil and aquatic systems. Iron (oxyhydr) oxides can sequester Cd via adsorption and …

Cadmium (Cd) stable isotopes provide a novel technique to investigate the fate of Cd in the
environment, but challenges exist for tracing the sources in the plants. We performed …

Abstract Initial Cadmium (Cd) isotope fractionation studies in cereals ascribed the retention
of Cd and its light isotopes to the binding of Cd to sulfur (S). To better understand the relation …

The drainage of rice soils increases Cd solubility and results in high Cd concentrations in
rice grains. However, plant Cd uptake is limited by sorption to iron plaques, and Cd …

The mechanism of reactive oxygen species (ROS) burst in rice cells induced by cadmium
(Cd) stress remains poorly understood. The present study shows that the burst of superoxide …

Anions accompanying inorganic fertilizers, such as chloride and sulfate ions, potentially
affect the solubility, uptake, and transport of Cd to rice grains. However, the role of anions in …

Biogeochemical processes of atmospherically deposited cadmium (Cd) in soils and
accumulation in rice were investigated through a three-year fully factorial atmospheric …

When rice plants grown in paddy fields with Cd content of 0.3–1.5 mg kg− 1, Cd quantities in
roots and straws were 2–7 times higher than that in topsoil. Return of these vegetative …
