| 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] |
