What is bromide in drinking water?

Bromide can be involved in the reaction between chlorine and naturally occurring organic matter in drinking-water, forming brominated and mixed chloro-bromo by- products, such as trihalomethanes or halogenated acetic acids, or it can react with ozone to form bromate.

Is bromide safe in drinking water?

Bromide is a naturally occurring element found in surface waters and groundwater. During drinking water treatment, bromide can combine with chlorine or other disinfectants, contributing to the formation of toxic tap water disinfection byproducts.

Is bromide toxic to humans?

Methyl bromide is highly toxic. Studies in humans indicate that the lung may be severely injured by the acute (short-term) inhalation of methyl bromide. Acute and chronic (long-term) inhalation of methyl bromide can lead to neurological effects in humans.

How do you remove bromide from drinking water?

Granular activated carbon (GAC) was used to remove bromide (Br⁻) and bromate (BrO(3)(-)) from drinking water in both bench- and pilot-scale experiments.

Why do they put bromine in water?

Bromine substances are disinfectants and can be used as an alternative for chlorine. In swimming pools, bromine is used against the formation and growth of algae, bacteria and odors in swimming water. In the United States, bromine has been used since 1936 to treat swimming water.

Is bromide cancerous?

While the National Institute for Occupational Safety and Health (NIOSH) lists methyl bromide as a potential occupational carcinogen [6], IARC ranks its carcinogenicity as unknown (group 3) [7]. There is evidence for a carcinogenic potential of methyl bromide based on its known genotoxic activity.

What happens if you drink bromide?

Ingestion of liquid bromine can cause abdominal pain and hemorrhagic gastroenteritis with secondary shock. Signs and symptoms might also include brown discoloration of mucous membranes and the tongue (1, 2).

Does tap water contain bromine?


Concentrations of bromide in fresh water typically range from trace amounts to about 0.5 mg/l. Concentrations of bromide in desalinated waters may approach 1 mg/l.

Is bromine and bromide the same?

Bromine is a chemical element of the halogen group, which includes fluorine, chlorine, iodine and astatine. Bromide is an anion of bromine, commonly found in trace amounts as salt in sea-water, along with sodium chloride (common table salt).

Which is safer chlorine or bromine?

Bromine: Is gentler on your skin than chlorine, but can be a bit more difficult to wash off after a long soak. If you or anyone who uses your hot tub on a regular basis has sensitive skin or any kind of upper respiratory difficulties, bromine will likely be the better choice.

Which is better chlorine or bromine?

Chlorine works faster to kill contaminants but for a shorter period of time, as it dissipates faster. Bromine kills contaminants more slowly but for a longer period of time; plus, it can help keep water chemistry more balanced due to its low pH, meaning less chemical adjusting is needed.

How do you make bromine water?

Dissolve the sodium bromine in the hydrochloric acid, mixing the compounds in a flask or beaker. Pour the mixture into the glass bottle. Add the bleach to the mixture in the bottle. Cap the bottle and swirl it gently to mix the ingredients.

What is bromine water made of?

Bromine water is an oxidizing, intense yellow-to-red mixture containing diatomic bromine (Br2) dissolved in water (H2O).

Where do you get bromine?

Bromine is found naturally in the earth’s crust and in seawater in various chemical forms. Bromine can also be found as an alternative to chlorine in swimming pools.

What foods contain bromide?

Bromide is most commonly found in the form of methyl bromide, a common pesticide used on strawberries; as brominated vegetable oil which is often added to citrus drinks and asthma inhalers; as a fire retardant in fabrics and mattresses; and as potassium bromate, a dough conditioner found in commercial bakery products …

What medications contain bromide?

Bromine is often found in certain medications like inhalers, nasal sprays and certain gaseous anesthetics. Bromine in the form of polybromo diphenyl ethers is used as a fire retardant in carpets fabrics, mattresses and upholstery. Bromine is often used for treatment of swimming pools and hot tubs.

Why is bromine important to humans?

Bromine, chemical symbol Br and atomic number 35, is a reddish-brown liquid that is being used in key applications such as water treatment, the reduction of mercury emissions, fire safety, energy storage and generation, production of pharmaceuticals and enhanced quality rubber.
