  1. Asthma in chemical workers exposed to aliphatic polyamines.

    Article - En anglais

    Following the identification of an index case of occupational asthma, we assessed the respiratory morbidity in 12 workers exposed to aliphatic polyamines in a chemical factory and in 60 unexposed workers in three other workplaces.

    Many amine workers reported symptoms of chronic cough (7/12), chronic phlegm (9/12), wheezing (4/12) and exertional breathlessness (3/12).

    These were significantly more frequent in exposed than in unexposed workers (P<0.01).

    They also had significantly greater diurnal variation in peak expiratory flow rates (DV-PEFR) than the unexposed workers (P<0.01).

    All four amine workers with wheezing reported onset of symptoms after employment at the factory, and all had DV-PEFR greater than 15%, compared to only one control worker (P<0.01).

    A second case of occupational asthma was confirmed by bronchial challenge test.

    The study indicated a very high risk of asthma and chronic airways disease and a need for stringent measures to protect the health of industrial workers exposed to aliphatic amines in Singapore.
