Inorganic chloramines
Inorganic chloramines comprise three compounds: monochloramine (NH 2 Cl), dichloramine (NHCl 2 ), and nitrogen trichloride (NCl 3 ). Monochloramine is of broad significance as a disinfectant for water. Inorganic chloramines are produced by the reaction of ammonia and hypochlorous acid or chlorine. An urban legend claims that mixing household bleach (aqueous sodium hypochlorite) with ammonia-based cleaners releases chlorine gas or mustard gas; in reality, the gas produced by the reaction is a mixture of inorganic chloramines.
Swimming pools
Chloramines are formed by reaction of chlorine used to disinfect swimming pools with ammonia and urea introduced into the pools by human perspiration, saliva, mucus, urine, and other biologic substances, and by insects and other pests. Chloramines, especially trichloramine, are responsible for most of the "chlorine smell" of pools, as well as for skin, eye, and respiratory irritation.
