  1. Exposure-response relationships in rhinitis and conjunctivitis caused by methyltetrahydrophthalic anhydride.

    Article - En anglais


    To examine exposure-response relationships in the occurrence of symptoms of the eyes and airways in workers exposed to methyltetrahydrophthalic anhydride (MTHPA).


    A population of 11 workers from 2 condenser plants (A and B) using epoxy resin with MTHPA underwent a questionnaire survey and serology investigations, and data obtained on 95 subjects in assembly and inspection lines were analyzed for this study.


    In all, 24 (65%) of 37 workers in plant A and 38 (66%) of 58 workers in plant B had positive MTHPA-specific IgE.

    The air levels of MTHPA detected in assembly and inspection lines were higher in plant A than in plant B (geometric mean 25.5-63.9 and 4.93-5.49 mug/m3. respectively).

    IgE-sensitized workers in each plant had significantly (P<0.05) more complaints regarding the eyes and nose than did unsensitized workers, suggesting that there is an IgE-mediated mechanism in most of these symptoms.

    The sensitized workers in plant A had higher frequencies for symptoms of the eyes, nose, and pharynx than did those in plant B (P<0.02).

    Furthermore, only 15% of persons often displayed work-related symptoms among the 20 symptomatic workers in plant B as compared with 73% of the 26 symptomatic workers in plant A (P<0.0001).

    These results can be explained by the difference in the MTHPA levels measured in the lines between the two plants. (...)
