Role of mineral nutrition in minimizing cadmium accumulation by plants.
Cadmium (Cd) is a highly toxic heavy metal for both plants and animals. The presence of Cd in agricultural soils is of great concern regarding its entry into the food chain. Cadmium enters into the soil-plant environment mainly through anthropogenic activities. Compounds of Cd are more soluble than other heavy metals, so it is more available and readily taken up by plants and accumulates in dif...

متن کاملNonruminant Nutrition: Mineral-Mineral Interactions: Implications for Nutrition
Inorganic elements (metals, non-metals, transition elements, and electrolytes commonly called “minerals” in nutrition science) are critical to all life processes as enzyme cofactors, stabilizers of proteins, structural components of tissues, second messengers, regulators of acid-base balance, participants in redox reactions, and for the maintenance of cellular electrical potential. For this rea...
