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 ...
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 .
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 ...
Inorganic bromine is found in the atmosphere and is quickly cycled between its gas and its particulate phase. Bromine gas (Br 2 ) undergoes an autocatalytic cycle known as the ' bromine explosion ', which occurs in the ocean and salt lakes such as the Dead Sea , where a high quantity of salts are exposed to the atmosphere.
Dow found a better permanent location at Freeport, Texas, where a seawater extraction plant started in 1940, and a second in 1943. [9] The Freeport plants recovered magnesium, sodium compounds, and chlorine, in addition to the bromine. The Freeport chemical operations are still active, but they stopped extracting bromine in 1969. [10]
Cucurbita foetidissima is a tuberous xerophytic plant found in the central and southwestern United States and northern Mexico. [3] It has numerous common names, but is most commonly called the buffalo gourd in English. The type specimen was collected from Mexico by Alexander von Humboldt and Aimé Bonpland sometime before 1817. [4]
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 .
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
