Bromide is present in typical seawater (35 PSU) with a concentration of around 65 mg/L, which is about 0.2% of all dissolved salts. Seafood and deep sea plants generally have higher levels than land-derived foods. Bromargyrite—natural, crystalline silver bromide—is the most common bromide mineral known but is still very rare. In addition to ...
Hundreds of known organobromine compounds are generated by terrestrial and marine plants and animals, and some serve important biological roles. [12] As a pharmaceutical, the simple bromide ion (Br −) has inhibitory effects on the central nervous system, and bromide salts were once a major medical sedative, before replacement by shorter ...
Selenium, which is an essential element for animals and prokaryotes and is a beneficial element for many plants, is the least-common of all the elements essential to life. [ 3 ] [ 63 ] Selenium acts as the catalytic center of several antioxidant enzymes, such as glutathione peroxidase , [ 11 ] and plays a wide variety of other biological roles .
Anthropogenic and natural sources of bromine. The major sources include sea spray, salt lakes, marshes, volcanos, anthropogenic sources. Sinks include exchange of brominated compounds with the stratospheric and troposphere.Bromine's chemistry is linked to other halogens such as chlorine and iodine amplify atmospheric cycling that contributes to troposphere and stratosphere ozone layer ...
Plants in the Bromeliaceae are widely represented in their natural climates across the Americas. One species (Pitcairnia feliciana) can be found in Africa. [30] They can be found at altitudes from sea level to 4,200 meters, from rainforests to deserts. 1,814 species are epiphytes, some are lithophytes, and some are terrestrial
These may be metal salts containing bromide ion such as potassium bromide, or more covalent bromides of metals or nonmetals such as tantalum(V) bromide or phosphorus tribromide. See also [ edit ]
Organobromine chemistry is the study of the synthesis and properties of organobromine compounds, also called organobromides, [1] which are organic compounds that contain carbon bonded to bromine. The most pervasive is the naturally produced bromomethane .
Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...
