Bromide is a chemical compound made by bromine with metals or radicals. Among the various bromides, especially potassium bromide is used in the medical field. Bromides have been found to have a depressive effect on the central nervous system in the human body. It has been used especially in the treatment of epilepsy. Bromides are mostly used for headaches because more effective drugs are developed today. In general, the effects of bromides on the body are in the form of relief.

The bromine salt is essentially a bromine-containing salt such as sodium bromide and potassium bromide. All bromides show drug and sedative effects on the central nervous system. For example, bromide drugs are also used in the treatment of insomnia caused by excessive anxiety.

Methyl bromide, a colorless and poisonous gas, has been used as an insecticide, especially for agricultural products in warehouses. The use of methyl bromide, a broad-acting pesticide that has been widely used in agricultural fields since 1940, was banned in 2009.

If too much bromide is taken into the body, it will damage the gastric membrane. In addition, a feeling of weakness, drowsiness and speech disorders, such as cause some discomfort.

During the ozonation of bromide ion containing water for disinfection purposes, many by-products such as bromate, brominated acetic acids and cyanobromide are formed if ammonia is present. The bromate ions formed in this way have been shown to produce carcinogenic effects. Therefore, determination of bromide in water has been important.

Bromide enters the groundwater near the sea due to sea water interference. Some surface waters also contain bromide due to industrial wastes. Under normal conditions, bromide content in drinking water is acceptable (rarely exceeds 1 mg / l).

Determination of bromide in drinking and potable water is carried out in authorized laboratories within the scope of chemical tests and the following standard is taken as basis in these studies:

  • TS 266 Waters - Waters for human consumption

According to this standard, bromide should not be present in drinking water.
