Selenium (Se), discovered by the Swedish chemist Jakob Berzelius in 1817, is a metalloid and states in group VIA with an atomic weight of 78.96. Selenium has five valence states common in nature, including selenide (2-), elemental Se (0), thioselenate (2+), selenite (4+), and selenate (6+). Selenium is an essential nutrient for humans and animals to form important selenoproteins, including glutathione peroxide, thioredoxin reductase.
The International Society for Selenium Research (ISSR) is a non-profit organization with a goal of promoting integrated and multidisciplinary selenium research efforts worldwide. The ISSR will foster the collaborative efforts of researchers and professionals in selenium research by providing a forum for interaction at international conferences and communication via the ISSR website and newsletter.
