background: possibility to trace-label albumin with isotopes results in information concerning its synthesis, breakdown, and distribution in the intra and extra cellular spaces. the iodination of albumin is a widespread procedure used in scientific studies. bromine not only is more reactive and less expensive than iodine, but bonds more easily with many elements. therefore, it could be a suitab...

a study was undertaken to investigate the role of placenta in transferring drugs containing bromine to the infant. 20 pregnant subjects were given bromine as kbr (500 mg/50 kg weight) 10h before the delivery the bromine content of the serum in the mother and the child was estimated by neutron.. 13 lrradlated at 2xlo activation analysis. samples were -2 -1 n em 5 for a period of one hour. a ge (...

A spectrophotometric study concerning the interactoin between iodine and bromine with tetrabutylammonium iodide (TBAI), tetrabutyl- ammonium bromide (TBABr) and cryptand 222 (C222) has been performed in dichloromethane solution at 25°C. The results are indicative of the formation of TBA+X3- and  C222X+X3-  t...

Bromine is one of the most abundant and ubiquitous trace elements in the biosphere and until recently had not been shown to perform any essential biological function in animals. A recent study demonstrated that bromine is required as a cofactor for peroxidasin-catalysed formation of sulfilimine crosslinks in Drosophila. In addition, bromine dietary deficiency is lethal in Drosophila, whereas br...

Bromine has a strong resource dependence. With the sharp decline of total amount and grade traditional brine resources, difficulty mining is increasing day by day, shortage bromine supply demand become normal situation. Therefore, it urgent to find new sources resources develop corresponding extraction technologies. Bromine-containing waste salt source bromine. The mature technology achievement...

 The major route of exposure is by inhalation.  Acute inhalation exposure to bromine vapour may cause upper respiratory effects, cough, headache, CNS effects and lacrimation.  Acute oral exposure to bromine results in central nervous system effects.  Deep partial skin loss and skin discolouration have been reported following acute dermal exposure to bromine.  Ocular exposure to bromine cau...

OBJECTIVE Inhaled 1-bromopropane decomposes easily and releases bromine ion. However, the kinetics and transfer of bromine ion into the next generation have not been clarified. In this work, the kinetics of bromine ion transfer to the next generation was investigated by using cross-fostering analysis and a one-compartment model. METHODS Pregnant Wistar rats were exposed to 700 ppm of 1-bromop...

Statistical models are developed for bromine incorporation in the trihalomethane (THM), trihaloacetic acids (THAA), dihaloacetic acid (DHAA), and dihaloacetonitrile (DHAN) subclasses of disinfection byproducts (DBPs) using distribution system samples from plants applying only free chlorine as a primary or residual disinfectant in the Information Collection Rule (ICR) database. The objective of ...

We report the first UV-vis spectroscopic study of bromine molecules confined in clathrate hydrate cages. Bromine in its natural hydrate occupies 51262 and 51263 lattice cavities. Bromine also can be encapsulated into the larger 51264 cages of a type II hydrate formed mainly from tetrahydrofuran or dichloromethane and water. The visible spectra of the enclathrated halogen molecule retain the spe...
