描述
Selenate, also known as selenic acid or disodium selenate, is a member of the class of compounds known as non-metal selenates. Non-metal selenates are inorganic non-metallic compoundscontaining a selenate as its largest oxoanion. Selenate can be found in a number of food items such as blackcurrant, allium (onion), common walnut, and pistachio, which makes selenate a potential biomarker for the consumption of these food products. Selenate can be found primarily in urine. The element selenium exhibits several valence states. Selenate is the least reduced, followed by selenite, and elemental selenium. The valence state is an important factor to the toxicity of selenium. Selenate is the form required by organisms that need selenium as a micronutrient. These organisms have the ability to acquire, metabolize and excrete selenium. The level at which selenium becomes toxic varies from species to species and is related to other environmental factors like pH and alkalinity that influence the concentration of selenite over selenate .
