Selenium salts are toxic in big amounts, but trace amounts are needed for cellular function in many life forms, as well as all animals. Selenium is a component in many multivitamins and other nutritional supplements, as well as baby formula. it's a part of the antioxidant enzymes glutathione peroxidase and thioredoxin reductase which indirectly decrease certain oxidized molecules in animals and some plants. it's also found in three deiodinase enzymes, which change one thyroid hormone to another. Selenium prerequisites in plants differ by species, with some plants requiring comparatively big amounts and others seemingly requiring none.
Dissolved free sulfides H2S, HS-, and S2-, are violent species for the corrosion of many metals like steel, stainless steel, and copper. Sulfides present in aqueous solution are accountable for stress corrosion cracking SCC of steel, and is aka sulfide stress cracking. Corrosion is a big concern in many industrial installations processing sulfides: sulfide ore mills, deep oil wells, pipelines transporting soured oil, Kraft paper factories. Microbially induced corrosion MIC or biogenic sulfide corrosion are caused by sulfate decreasing bacteria producing sulfide that's emitted in the air and oxidized in sulfuric acid by sulfur oxidizing bacteria. Biogenic sulfuric acid reacts with sewerage materials and most usually causes mass loss, cracking of the sewer pipes and finally, structural collapse. This kind of deterioration is a big procedure influencing sewer systems global and leading to high treatment costs. also host pests and illnesses that can spread to cultivated crops. Charlock and Shepherd's purse may carry clubroot, eelworm may be harboured by chickweed, fat hen and shepherd's purse, while the cucumber mosaic virus, which can devastate the cucurbit family, is carried by a range of different weeds as well as chickweed and groundsel.

What kind of a shampoo to use?
Selenium is found in metal sulfide ores, where it partially replaces the sulfur. Commercially, selenium is made as a byproduct in the refining of these ores, usually throughout production. Minerals that are pure selenide or selenate compounds are recognized but rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and can be used in photocells. Applications in electronics, once important, have been usually supplanted by silicon semiconductor devices. Selenium is still used in some types of DC power surge protectors and one kind of fluorescent quantum dot.
