Treatment · 1 Eintrag

EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

Health Effects · 1 Eintrag

Bromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses.

Toxicity Summary · 2 Einträge

IDENTIFICATION AND USE: Ammonium bromide exists as white crystals or granules. It is used in process engraving and lithography, fireproofing of wood, and as a corrosion inhibitor. Bromide- containing medications is a prominent former use. HUMAN EXPOSURE AND TOXICITY: The warning symptoms of bromide intoxication, bromism, include mental dullness, slurred speech, weakened memory, apathy, anorexia, constipation, drowsiness and loss of sensitivity to touch and pain. These symptoms disappear on discontinuing the drug, but continued use leads to more serious symptoms including restlessness, disorientation, ocular disturbances, ataxia, hallucinations, delirium, stupor and coma. Bromide rash, of an acneform, nodular, or sometimes erythematous type, is of fairly common occurrence but may be absent even in patients who have developed severe mental symptoms. Transplacental bromism had been described in the literature. ANIMAL STUDIES: Ammonium bromide was not irritating to skin, but slightly irritating to eyes in rabbits. Ames test conducted in Salmonella typhimurium strains TA1535,TA100,TA1538,TA98,TA1537 with and without metabolic activation was negative.

Bromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes.

Biological Half-Life · 1 Eintrag

The biological half-life of bromide ions in human blood was studied in 10 human healthy volunteers. Br(82) labelled ammonium bromide was given orally as a water solution. The biological half-life of bromide ions was found to be about 12 days.

Metabolism/Metabolites · 1 Eintrag

Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626)

Absorption, Distribution and Excretion · 4 Einträge

The biological half-life of bromide ions in human blood was studied in 10 human healthy volunteers. Br(82) labelled ammonium bromide was given orally as a water solution. The biological half-life of bromide ions was found to be about 12 days. The bromide ratio red blood cells/serum was found to be about 0.45. No bromide was found to be incorporated in fat, extracted from plasma and hemolyzed blood cells by ether. Nor was any bromide found to be incorporated in blood proteins.

The excretion of bromide by the urine was studied in 13 healthy voluteers who were given Br(82) ammonium bromide orally as water solution. Urine samples were collected every 2 hr approx. for 5 days. Blood and saliva bromide levels were also measured in 6 of the subjects. The biological half life of bromide was equal in blood, urine and saliva, about 12 days. Nearly all of the labelled bromide administered was found to be excreted in the urine. The mean concentration of labeled bromide in urine and saliva was about equal and 150% of the blood level. The excretion of bromide varied during the day - there was hardly any found in urine during sleep.

The concentration of Br-82 (in the form of NH4-82-Br containing 12 mg. bromine/mCi) in the thyroid, muscle and blood was studied in rats. The animals were injected ip with 30 uCi 82- Br in 2 mL 0.9% NaCl solution. Results of the study indicated that under normal conditions bromine is not concentrated by the thyroid. After stimulation by TSH there is an increased uptake by the gland. There was no evidence that bromine is metabolized further in the thyroid gland.

Single doses of an aqueous solution of Br(82)-ammonium bromide were injected into tail veins of pregnant albino mice 2 days before post-partum. The mice were sacrificed after 5 or 20 min.,1,2,4,24 or 48 hrs and the distribution of the Br(82) in the tissues of the dams and the fetuses had been studied by autoradiography. The distribution was found to be similar at the various time periods studied. The radioactivity was excreted slowly. Blood levels remained high and exceeded those recorded for most organs and tissues. Bromide gradually accumulated in the central nervous system. The level in the thyroid was relatively high but did not exceed levels in the blood. Bromide showed transplacental passage and most of the radioactive bromide was found in the bones of the fetuses, but the level was not as high as in the cartilage of the dams (which did not exceed blood levels). The following tissues accumulated bromide at higher conc. than the blood after 24 hrs: Gastric mucosa and contents, urinary bladder contents, blood-vessel walls and retina.

Methods of Manufacturing · 5 Einträge

It is prepared by the reaction of hydrobromic acid and ammonia or preferably by the direct reaction of ammonia (in a slight excess) with bromine in water. ... Concentration of solutions produces the crystalline product, whereas a powder results from spray-drying.

... Prepared by the reaction of ammonia with iron(II) bromide or iron(III) bromide.

For ammonium bromide, another method involving reaction of an aqueous bromine solution and iron filings has been used. The solution of ferrous and ferric bromide thus formed then reacts with ammonia to precipitate hydrated oxides of iron. Ammonium bromide can be recovered by crystallization from the concentrated liquor.

Action of hydrobromic acid on ammonium hydroxide with subsequent crystallization.

Ammonium bromide is manufactured by a reaction between ammonia and bromine. The solution is then filtered, crystallized and dried.
