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.

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. Bromate is also a potential carcinogen. (L625, L626, L627, L638)

Safe for use in cosmetics, with qualifications

IDENTIFICATION AND USE: Sodium bromate is a solid and a strong oxidant. It is used as an analytical reagent, as a neutralizing solution in hair permanents, and an auxiliary agent in printing and dyeing. HUMAN STUDIES: For decades, it has been known that ingested sodium bromate can induce hearing loss. Hearing loss onset, following high-dose ingestion, is generally rapid occurring within 4-16 hr and of a severe to profound degree. Unlike the sensorineural hearing loss which is generally irreversible, bromate-induced tinnitus, which is less well-studied, may be permanent or temporary. It is not clear whether actual bromate-induced vestibulotoxicity occurs in clinical populations. The primary sites of lesion for bromate-induced ototoxicity appear to be in the cochlea. Several cases of acute bromate intoxication have been reported in humans following accidental or suicidal ingestion of permanent hair wave neutralizing solutions. These products usually contain either 2% potassium bromate or 10% sodium bromate. The most common acute signs are severe gastrointestinal irritation (vomiting, pain, diarrhea) and central nervous system depression (lethargy, hypotension, hypotonicity, loss of reflexes). Anemia from intravascular hemolysis may also occur. These effects are usually reversible. Later sequelae (usually within several days) include marked renal injury and hearing loss. Death from renal failure may ensue if medical intervention is not successful. A 17-year-old hairdresser developed sodium bromate poisoning after drinking a cup of hair neutralizer in a suicide attempt. She presented 1 week later with anuria, required hemodialysis for 5 days, and subsequently recovered. A case of sodium bromate poisoning is reported in a 21-month-old boy who ingested approximately 6 oz of a professional hair waving neutralizer and developed acute renal failure. In another case, a 34 year old man attempted suicide by ingestion of 14 g of sodium bromate. He developed a cerebral lesion due to sodium bromate intoxication which was confirmed on MRI, SPECT, auditory brainstem response (ABR) and sensory evoked potential (SEP). ANIMAL STUDIES: Sodium bromate is reported to have skin and eye irritant properties. It was a mild sensitizer in the Buehler test in guinea pigs. In guinea pigs, subcutaneous injections of 100 mg/kg bw sodium bromate produced cochlear damage--ie degenerative changes of the outer hair cells by 24 hr. Animals killed at that time revealed hyaline degeneration, cloudy swelling and necrosis of the epithelial cells in renal tubules, which were most severe in the proximal convoluted tubules. After injection of 200 mg/kg bw, there was more rapid onset of similar effects. The reproductive toxicity of sodium bromate in rats was evaluated in a short-term test. No changes were observed in the reproductive function of the females. Males showed no treatment-related histological changes in the kidneys, liver, spleen, testis or epididymis, but the activity of serum alanine aminotransferase was decreased by 14% at the two higher doses. There was a significant (18%) decrease in epididymal sperm density in males at the high dose. Sodium bromate was tested in the Ames test, the micronucleus test on mouse bone marrow, and the recessive lethal test using Drosophila. It was negative in the Ames test and in the Drosophila recessive lethal test. However, it showed significant mutagenic effects in a dose-dependent manner in the mouse micronucleus test system. ECOTOXICITY STUDIES: sodium bromate produced a weak induction of DNA damage to whole zebrafish embryos. Developmental effects occurred at a range of concentrations 20-100 ug/mL.

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)

/AQUATIC SPECIES/ Acute toxic effects of potassium bromate, sodium bromate and potassium bromide on luminescent bacteria, water flea, green alga and zebrafish were studied using standard toxic testing methods. The results showed that the pollutants had no effect on the luminous intensity of luminescent bacteria. The 96 hr EC50 of potassium bromate on Scenedesmus obliquus was 738.18 mg/L, 48 hr EC50 on Daphnia magna and Moina was 154.01 mg/L was 161.80 mg/L, while 48 hr LC50 was 198 52 mg/L, 175.68 mg/L, and 96 hr LC50 on zebrafish was 931.4 mg/L. The 96 hr EC50 of sodium bromate on Scenedesmus obliquus was 540.26 mg/L, 48 hr EC50 Daphnia magna and Moina was 127.90 mg/L, 111.07 mg/L, while 48 hr LC50 was 161.80 mg/L, 123.47 mg/L, and 96 hr LC50 on zebrafish was 1065.6 mg/L. But the effects of potassium bromide on the above several kinds of aquatic organisms were far smaller than those of potassium bromate and sodium bromate. The toxic effects on test organisms were due to the impacts of bromate after the comparison of different pollutants, and the effects were more obvious with the increase of exposure time. The order of sensitivity to the toxic effects of bromate was Daphnia magna, Moina > Scenedesmus obliquus > zebrafish > Chlorella vulgaris, luminescent bacteria.

/AQUATIC SPECIES/ Ballast water treatment has become a major issue in the last decade due to the problem of invasive species transported and released by the uptake and discharge of ballast water for shipping operations. One of the important issues considering ballast water treatment is to determine whether treated ballast water, once discharged, is safe to the aquatic environment. The International Maritime Organization (IMO) Marine Environmental Protection Committee (MEPC) has determined that prior to approval of a ballast water management system, aquatic toxicity data must be available for both the active substance and relevant byproducts. Many proposed ballast water treatment systems use chlorine as the active ingredient. Although there are sufficient toxicity data concerning active substances such as chlorine, there are limited toxicity data concerning disinfection (halogenated) byproducts including dibromochloromethane, four haloacetic acids and sodium bromate. Acute and chronic toxicity were determined for these disinfection byproducts (DBPs). Acute toxicity values ranged from 96-hr LC50s of 46.8 mg/L for Daphnia magna for both dibromochloromethane and sodium bromate to a 96-hr LC50 of 376.4 mg/L for Cyprinodon variegatus for tribromoacetic acid. Acute Isochrysis galbana population growth effect values ranged from a 72-hr EC10 of 39.9 mg/L for dichloroacetic acid to a 72-hr EC50 of 15,954 mg/L for sodium bromate. Chronic toxicity mortality/reproduction effects values for D. magna ranged from a 21-day IC25 of 160.9 mg/L for tribromoacetic acid to a 21-day LOEC of 493.0 mg/L for trichloroacetic acid. Chronic toxicity mortality/growth values for C. variegatus ranged from a 32-day IC25 of 246.8 mg/L for trichloroacetic acid to a 32-day LOEC of 908.1 mg/L for tribromoacetic acid. I. galbana 96-hr chronic population growth effects values ranged from an EC10 of 38.5 mg/L for trichloroacetic acid to an LOEC of 500.0 mg/L for tribromoacetic acid. Acute to chronic ratios for all of these DBPs ranged from 0.8 to 3.0. Based on toxicity/ecorisk categories generated by the U.S. Environmental Protection Agency, these disinfection byproducts would be considered either slightly toxic or practically nontoxic to the aquatic organisms tested.

/AQUATIC SPECIES/ Disinfection by-products /DBPs/ are contaminants produced during drinking water disinfection. Several DBPs have been implicated in a variety of toxic effects, mainly carcinogenic and genotoxic effects. Moreover, DBPs exposure has also been associated with an increased risk of developmental effects. In this study, the developmental toxicity and genotoxicity of 10 DBPs (four trihalomethanes [THMs], five haloacetic acids [HAAs] and sodium bromate) in the zebrafish embryo model were evaluated. Embryos exposed for 72 hours were observed for different endpoints such as growth, hatching success, malformations and lethality. THMs exposure resulted in adverse developmental effects and a significant reduced tail length. Two HAAs, tribromoacetic acid and dichloroacetic acid, along with sodium bromate were found to cause a significant increase in malformation rate. Chloroform, chlorodibromomethane and sodium bromate produced a weak induction of DNA damage to whole embryos. However, developmental effects occurred at a range of concentrations (20-100 ug/mL) several orders of magnitude above the levels that can be attained in fetal blood in humans exposed to chlorinated water. In conclusion, the teratogenic and genotoxic activity observed by some DBPs in zebrafish reinforce the view that there is a weak capacity of disinfection products to cause developmental effects at environmentally relevant concentrations.

/AQUATIC SPECIES/ Striped bass eggs (12 hr after fertilization) and larvae (4 days after hatching) and juvenile spot were exposed to a series of bromate concentrations (including sodium bromate) for 4, 10, and 10 days, respectively, using a static replacement bioassay technique. Newly hatched striped bass prolarvae were most sensitive to bromate and had a 96 hr median lethal concentration of (LC50) 30.8 mg/L (as bromate). Four-day-old striped bass larvae were less sensitive, with 2- to 10-day LC50s ranging from 605.0 to 92.6 mg/L bromate, resp. Juvenile spot were least sensitive, with 1- to 10-day LC50s ranging from 698.0 to 278.6 mg/L bromate, respectively.

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)

/SIGNS AND SYMPTOMS/ For decades, it has been known that ingested potassium bromate and sodium bromate can induce hearing loss. Hearing loss onset, following high-dose ingestion, is generally rapid occurring within 4-16 hr and of a severe to profound degree. Unlike the sensorineural hearing loss which is generally irreversible, bromate-induced tinnitus, which is less well-studied, may reportedly be permanent or temporary. It is not clear whether actual bromate-induced vestibulotoxicity occurs in clinical populations. The primary sites of lesion for bromate-induced ototoxicity appear to be in the cochlea. However, possible effects on the VIIIth nerve and central auditory system have not been fully investigated. Based on animal studies, in the cochlea, bromate damages the stria vascularis, Reissner's membrane, inner and outer hair cells, Claudius cells and inner sulcus cells. Physiologically, bromate reduces the endocochlear potential, cochlear microphonics, and electrophysiologic auditory thresholds. Possible mechanisms are discussed. The effects of long-term low-dose bromate exposure on hearing have not been studied. These effects, if they occur, may not be readily detected in many clinical populations, because idiopathic hearing loss occurs commonly in the population as a whole...

/SIGNS AND SYMPTOMS/ Several cases of acute bromate intoxication have been reported in humans following accidental or suicidal ingestion of permanent hair wave neutralizing solutions. These products usually contain either 2% potassium bromate or 10% sodium bromate. The most common acute signs are severe gastrointestinal irritation (vomiting, pain, diarrhea) and the Central Nervous System depression (lethargy, hypotension, hypotonicity, loss of reflexes). Anemia from intravascular hemolysis may also occur. These effects are usually reversible. Later sequelae (usually within several days) include marked renal injury and hearing loss. Death from renal failure may ensue if medical intervention is not successful. If support is successful, renal function generally returns after 5-10 days. Hearing loss is usually irreversible. Estimated doses in these cases ranged from about 20 to 1,000 mg BrO3-/kg.

/CASE REPORTS/ The clinical manifestations of sodium bromate intoxication include among others acute renal failure and deafness. Most of the toxic manifestations are reversible with the exception of renal failure and deafness. This patient ingested about 7.5 g of sodium bromate powder, which produced gastrointestinal irritation, hypotension, fatigue, deafness, acute renal failure, anemia and peripheral neuropathy. Hemodialysis was performed three times due to acute renal failure, although the renal function improved, it did not recover completely. The patient was discharged with BUN: 42 mg/dL and creatinine: 3.4 mg/dL; she was still deaf.

/CASE REPORTS/ A 17-year-old hairdresser developed sodium bromate poisoning after drinking a cup of hair neutralizer in a suicide attempt. She presented 1 week later with anuria, required hemodialysis for 5 days, and subsequently recovered. Sensorineural hearing loss, often a characteristic finding, was absent. Early diagnosis of bromate intoxication requires an appreciation that it commonly occurs in hairdressers, may be accompanied by deafness, and may present with insidious anuria.

Sodium bromate's production and use as an analytical reagent(1,2), in hair treatment formulations and in continuous or batch dyeing process in sulfur and vat dyes(2) may result in its release to the environment through various waste streams(SRC). Its use in gold mining applications(2) may result in its direct release to the environment(SRC).

Maximum contaminant level (MCL) for disinfection byproducts: Bromate, MCL: 0.010 mg/L. /Bromate/

Bromate is listed in the 2018 Edition of the Drinking Water Standards and Health Advisories Tables.

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)

A study to evaluate the potential in vivo transdermal absorption of bromate from a hair neutralizer formulation containing 10.17% sodium bromate (BrO,-) has also been reported. In this study 0.5 mL of the hair neutralizer was spread over a 5 sq cm shaved area of 24 albino guinea pigs and allowed to remain for 15 min (3 x the normal 5-min exposure used during actual hair treatment). At the end of the treatment, the exposed areas were rinsed with water several times and dried. Twenty-four control animals were exposed to a physiological saline solution. Two separate studies, each using the same procedures, were reported. The study used a hair neutralizer containing 10.17% sodium bromate (8.59% BrO,-). Blood samples were collected from both the test and control animals from the retro-orbital sinus at 1, 2, 3 and 4 hr. Urine samples were also collected. ... The recovery of bromate by the method used was estimated to be 87%, with a detection limit of 76 ppb BrO,-. The investigators reported that no bromate was found in the blood samples of the controls or the animals treated with hair neutralizers containing 10.17% sodium bromate (8.59% BrO3-). A separate parallel study using the same exposure method was conducted to measure the amount of bromide in the blood of treated and untreated guinea pigs. The bromide was measured by X-ray fluorescence with a limit of detectability of 0.5 ppm. Twenty-four animals were used in the controls and in each of the assays of the hair neutralizers. Elevated serum concentrations of bromide were observed in some of the treated animals in one of the assays of one hair neutralizer, but not in the other. The investigators concluded that bromate does not penetrate through guinea pig skin above the minimal limit of detection (76 ppb), and that the bromide that was detected in serum is the nonoxidative form of bromine.
