| Alternative Name | Nitrogen trichloride |
| CAS Number | 10025-85-1 |
| Formula | Cl3-N |
| Major Category | Nitrogen Compounds |
| Synonyms | Agene; Chlorine nitride; Trichloramine; Trichlorine nitride; Nitrogen trichloride; [ChemIDplus] |
| Category | Other Nitrogen Compounds |
| Sources/Uses | A byproduct of water chlorination, it is volatile and strongly irritating; May make the lung more susceptible to allergens; It is formed when organic matter in sweat and urine react with chlorine in swimming pools; [Reference #2] |
| Comments | Occupational asthma in indoor pool workers (lifeguards and a swimming teacher) confirmed by specific bronchoprovocation testing; [Malo] Chloramines include chloramide (NH2Cl), dichloramide (NHCl2), and trichloramide (NCl3). Tricloramide, also called nitrogen chloride or nitrogen trichloride, was the predominant vapor found in the indoor pool environment with a high chlorine to nitrogen ratio. All three swimming pools the study had been treated with sodium hypochlorite. Measured levels of NCl3 ranged from 0.23-0.57 mg/m3 in one pool and 0.1-0.31 in another pool. The concentration used for the challenge tests was 0.5 mg/m3. All 3 workers had immediate asthmatic reactions to the challenge tests, and one had an additional late reaction. [See Reference #1] |
