title: Occupational asthma caused by pyrazolone derivative used in silver halide photographic paper.
abstract: 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.
