Halogenwasserstoffprodukt
Halogenwassers, in the sense used in chemistry and environmental science, refers to water that contains halogen elements (fluorine, chlorine, bromine, iodine) or halogenated compounds. In practice the term is used in German-language literature to discuss either natural halide content in water or water that has been treated with halogens for disinfection or other purposes. The concept encompasses both inorganic halide ions dissolved in water and organic compounds in which a halogen atom is bound to carbon or other atoms.
Natural waters can contain halide ions such as chloride, fluoride, bromide, and iodide derived from geology,
Halogenated water types include chlorinated water (drinking and swimming pools), fluoridated water (fluoride-added for caries prevention),
Regulation typically seeks to minimize health risks by limiting concentrations of halogens and halogenated disinfection byproducts
