Occupational asthma caused by pyrazolone derivative used in silver halide photographic paper

Chest. 2000 Jul;118(1):246-8. doi: 10.1378/chest.118.1.246.


Occupational asthma has been documented in workers exposed to a wide variety of chemical compounds. Reactive dyes have been described as causing occupational asthma in textile industry workers. We report a case of occupational asthma resulting from exposure to pyrazolone dye used in silver halide photographic paper. There is a need for both further surveys of workers exposed to other reactive dyes and careful preventive measures in the handling of such compounds.
