Plants | Free Full-Text | Selenium Toxicity in Plants and …

Selenium (Se) is a widely distributed trace element with dual (beneficial or toxic) effects for humans, animals, and plants. The availability of Se in the soil is reliant on the structure of the parental material and the procedures succeeding to soil formation. Anthropogenic activities affect the content of Se in the environment. Although plants are the core source of Se in animal and human ...

By supplementing Yara fertilizers with sodium selenate, plants can convert the inorganic selenium into organic forms, which are more efficiently utilized by humans and animals. For example: Applying selenium in grassland fertilizer increases the selenium uptake by the grass and therefore increase the selenium supply to the animals and humans via meat and dairy products.

The selenium chemistry of plants has been reviewed several times (Brown and Shrift, 1982; Anderson and Scarf, 1983), most recently by Lauchli (1993). Interaction between S and Se uptake and assimilation by plants is expected, particularly when S and Se are present as sulfate (SO 4 2- ) and selenate (SeO 4 2- ), their most chemically stable forms in aerated, neutral and near-neutral natural waters.

The selenium content of soil affects the amounts of selenium in the plants that animals eat, so the quantities of selenium in animal products also vary [2,5]. However, selenium concentration in soil has a smaller effect on selenium levels in animal products than in plant-based foods because animals maintain predictable tissue concentrations of selenium through homeostatic mechanisms.
