Selenium in the SoilPlant Environment: A Review
Selenium (Se) exhibits a "doubleedged" behavior in animal and human nutrition. It is a micronutrient required in low concentrations by animals and humans, but toxic at high concentrations. Selenium deficiency has been associated with cancer and other health problems. Selenium requirements are commonly met through soils and plants such as wheat, rice, vegetables and maize in many countries.

Calcium. Calcium is a secondary plant macronutrient and is vital for healthy plants. It is required for the formation of new cells so is needed in order for roots, stems and leaves to grow. It is also used by plants when they respond to pest and disease attacks.
Distribution Selenium in Nutrition NCBI Bookshelf
Selenium is widely distributed in minute amounts in virtually all materials of the earth's crust, having an average abundance of about 0.09 ppm (Lakin, 1972). Its occurrence has been determined in a wide variety of rocks, minerals, lunar and volcanic materials, fossil fuels, soils, plant materials, and waters.

Selenium in biology Wikipedia
In plants, it sometimes occurs in toxic amounts as forage, e.g. locoweed. Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase.
The roles of selenium in protecting plants against abiotic
1. Introduction. Selenium (Se) had long been considered as a toxic element until it was found also to be essential in 1957 (Schwarz and Foltz, 1957).Since then, the role of Se in mitigating environmental stress has been extensively investigated in animals and humans and, to a lesser extent, in plants.

Jan 27, 2011 · Selenium is an essential micronutrient to sustain human and animal health. However it is one of the most common micronutrient deficiencies in malnutrition. Low levels of selenium (Se) have been associated with a higher risk of cardiovascular diseases and cancer in humans Selenium is mainly provided by plant foods (such as cereal), meat and dairy products.

The selenium chemistry of wastewater varies greatly between industries, between treatment plants in the same industry, and even within different processes at a single treatment plant. Selenium's complex chemistry makes it challenging to treat.
Frontiers Selenium Biofortifiion in Fragaria
Selenium (Se) is an essential nutrient for humans, due to its antioxidant properties, whereas, to date, its essentiality to plants still remains to be demonstrated. Nevertheless, if added to the cultivation substrate, plants growth resulted enhanced. However, the concentration of Se in agricultural soils is very variable, ranging from 0.01 mg kg1 up to 10 mg kg1 in seleniferous areas.
