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.

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. (L626, L627, A543)

Bromine vapour causes irritation and direct damage to the mucous membranes. Symptoms include lacrimation, rhinorrhoea, eye irritation with mucous secretions from the oropharyngeal and upper airways, coughing, dyspnoea, choking, wheezing, epistaxis, and headache. The bromide ion is a central nervous system depressant producing ataxia, slurred speech, tremor, nausea, vomiting, lethargy, dizziness, visual disturbances, unsteadiness, headaches, impaired memory and concentration, disorientation and hallucinations. This is called bromism. (L626, L627)

/HUMAN EXPOSURE STUDIES/ Bromides (including ammonium bromide) have been widely used for their sedative and anticonvulsant effects but, because the blood concentration necessary to produce a therapeutic effect is usually close to that at which toxic effects become evident, they have been replaced by other agents. DOSE: 1 to 6 g daily in divided doses. TOXIC EFFECTS: 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 occurance but may be absent even in patients who have developed severe mental symptoms. There is a clear evidence between blood-bromide concentration and symptoms, though individuals vary greatly. A toxic concentration can be reached very rapidly if the intake of chloride is reduced. High concentration of bromide has an irritant action on the stomach. A blood bromide concentration of 1 g (12.5 mmol) per litre is often regarded as the minimum intoxication level, though toxic symptoms may occur at lower concentrations, 2g/L produces toxic symptoms in most cases and 3 g/L is dangerous to life.

/SIGNS AND SYMPTOMS/ In addition to sedative and anticonvulsant effects, bromide produces a number of neuropsychiatric changes. in retrospective studies, it was found that many patients who were hospitalized in psychiatric institutions in the mid-20th century in fact had bromide intoxication.

/CASE REPORTS/ A 22-day-old girl was brought to the emergency department (ED) by her parents for excessive sleepiness and decreased oral intake over the prior 48 hours. Her birth history was unremarkable and her parents had no significant past medical history. Routine newborn exam and screens were also normal at birth. She had followup visits with a pediatrician and had been gaining weight appropriately. The parents stated that the child had some "colic" 2 weeks prior and her urine output was slightly decreased, but otherwise she had no recent illness, fever, chills, vomiting, diarrhea, rash, or excessive crying. All other systems reviews were negative. Further questioning revealed that the parents had been adding Cordial de Monell, an "elixir" for colic, to each meal around the clock for about 12 days prior to the patient's current symptom onset. It was purchased locally, and is commonly used in the Dominican Republic and in the expatriate Dominican community in the US. The resident physician who was caring for this patient had a similar cultural background, was familiar with this product, and remembered it contained "bromuro de potasio." The parents later brought in the actual product, confirming potassium bromide as a listed ingredient. The New York City Poison Control Center was consulted regarding whether exposure to potassium bromide could explain this patient's presentation. ... We believe this child suffered from excess therapeutic sedative exposure due to her size, age, and repeated exposure. Bromism is not nearly as common as it once was, but several forms of bromide are still readily available. This diagnosis should be included in the differential diagnosis of patients who present with sedative-hypnotic-type intoxication. Elevations in the reported serum chloride levels and a negative anion gap are helpful findings if present, but our case and others before confirm that the lack of these features do not rule out this poisoning. This case further illustrates the need for clinicians to be diligent in obtaining thorough medication, dietary, herbal supplement, social, occupational, and cultural histories from their patients. Aggressive hydration with chloride-containing solutions is the cornerstone of treatment, and in severe cases dialysis may be considered. Bromides are not gone, and bromism should not be forgotten. /Bromides/

/CASE REPORTS/ Case reports of 8 patients with positive bromide tests and symptoms of bromide intoxication are presented. The patients, who had ingested Alva Tranquil, Nervine or Bromo-Seltzer (potassium bromide, sodium citrate, and citric acid), had significant histories of alcoholism. In 1 case, ingestion of 25 Nervine tablets produced a serum bromide level of 360 mg/100 mL. Toxic signs and symptoms are usually seen when serum bromide levels exceed 80 mg/100 ml. Clinical manifestations, diagnosis, and treatment of brominism are presented.

/LABORATORY ANIMALS: Acute Exposure/ Eye Irritation: Rabbit, Slightly irritating

/LABORATORY ANIMALS: Acute Exposure/ Skin Irritation: rabbit, nonirritating

/GENOTOXICITY/ Ames test /was conducted in/ Salmonella typhimurium strains TA1535,TA100,TA1538,TA98,TA1537 at concentrations 250, 500, 1250, 2500, 5000 ug/plate, with and without metabolic activation. The test levels selected were based on results of a preliminary toxicity test in strain TA98. Each test was conducted in duplicate and was carried out on two separate occasions. Positive controls (sodium azide, ICR-191, 4-nitro-o-phenylenediamine (NPD), 2-aminoanthracene) induced significant increases in reverant colony numbers with all strains, confirming sensitivity of the cultures and activity of S-9 mix. No significant increases in reversion to prototrophy were obtained with any of the 5 bacterial strains at the compound levels tested, either in the absence or presence of S-9 mix. Ammonium bromide was concluded to be devoid of mutagenic activity under the conditions of the study.

According to the 2012 TSCA Inventory Update Reporting data, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of ammonium bromide is 1 to 99; the data may be greatly underestimated(1).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 16,770 workers (3,784 of these were female) were potentially exposed to ammonium bromide in the US(1).

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Bromine, methyl bromide, and related compounds/

Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water.

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.

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)

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.
