  1. Point source sulphur dioxide peaks and hospital presentations for asthma.

    Article - En anglais

    Objective

    To examine the effect on hospital presentations for asthma of brief exposures to sulphur dioxide (SO2) (within the range 0-8700 mug/m3) emanating from two point sources in a remote rural city of 25 000 people.

    Methods-A time series analysis of SO2 concentrations and hospital presentations for asthma was undertaken at Mount Isa where SO2is released into the atmosphere by a copper smelter and a lead smelter.

    The study examined 5 minute block mean SO2 concentrations and daily hospital presentations for asthma, wheeze, or shortness of breath.

    Generalised linear models and generalised additive models based on a Poisson distribution were applied.

    Results

    There was no evidence of any positive relation between peak SO2 concentrations and hospital presentations or admissions for asthma, wheeze, or shortness of breath.

    Conclusion-Brief exposures to high concentrations of SO2 emanating from point sources at Mount Isa do not cause sufficiently serious symptoms in asthmatic people to require presentation to hospital.
