Is selenium poisonous?
Selenium is a naturally occurring substance that is toxic at high concentrations but is also a nutritionally essential element. Hydrogen selenide is the most acutely toxic selenium compound. Acute (short-term) exposure to elemental selenium, hydrogen selenide, and selenium dioxide by inhalation results primarily in respiratory effects, such as irritation of the mucous membranes, pulmonary edema, severe bronchitis, and bronchial pneumonia. Epidemiological studies of humans chronically (long-term) exposed to high levels of selenium in food and water have reported discoloration of the skin, pathological deformation and loss of nails, loss of hair, excessive tooth decay and discoloration, lack of mental alertness, and listlessness. Epidemiological studies have reported an inverse association between selenium levels in the blood and canceroccurrence and animal studies have reported that selenium supplementation, as sodium selenate, sodium selenite, and organic forms of selenium, results in a reduced incidence of several tumor types. The only selenium compound that has been shown to be carcinogenic in animals is selenium sulfide, which resulted in an increase in liver tumors from oral exposure.
The element Selenium is very poisonous, yet your body needs tiny amount of it to be healthy. Most commonly, selenium is found in dandruff shampoos.
Selenium is an atomic element with 34 electrons and 34 protons. Stable versions (isotopes) have from 42 to 44 neutrons. It is necessary in very small amounts to support life, otherwise it is poisonous. Selenium at one time was the main source for transistors and diodes because of its semiconductor properties.
Selenium is not a who. Selenium is a material.
***Semi-spoiler alert! *** In the 1982 novel "Banker", by Dick Francis, selenium is used not for the purpose of killing people, but rather to create birth defects in racehorses. The bad guys are willing to murder- but not with the poisonous element mentioned. One of Francis' best, in my humble opinion.

None. Your question doesn't make sense because there is no family of elements that are all poisonous nonmetals. Elemental halogens are poisonous but at least two of them (chlorine and iodine) are needed by your body but not in their elemental form. They must be part of an ionic compound. Oxygen, sulphur and selenium are also needed by your body but other than oxygen, the others must also be part of a compound and not… Read More
