ABSTRACT
The paper presents some information about selenium (Se) and its biological role in the ecosystem. Se is a trace element for mammals. It has been shown to be a natural component in the enzyme glutathione peroxydases and other selenoproteins. Se participates in various biological processes, such as antioxidant defence, thyroid hormone production, and immune responses. The concentration of Se in organisms varies widely between geographical areas, depending on its content in the soil, plants, and dietary intake. In larger amounts it can be toxic (acute or chronic selenosis). Its deficit in diet can trigger the development of some chronic diseases (Keshan, Kashin- Beck).
