  1. Effects of low ambient levels of ozone and sulfates on the frequency of respiratory admissions to Ontario hospitals.

    Article - En anglais

    To investigate the acute respiratory health effects of ambient air pollution, the number of emergency or urgent daily respiratory admissions to 168 acute care hospitals in Ontario were related to estimates of exposure to ozone and sulfates in the vicinity of each hospital.

    Ozone levels were obtained from 22 monitoring stations maintained by the Ontario Ministry of the Environment for the period January 1,1983 to December 31,1988.

    Daily levels of sulfates were recorded at nine monitoring stations representing three different networks operated by the Ontario Ministry of the Environment and Environment Canada.

    Positive and statistically significant associations were found between hospital admissions and both ozone and sulfates recorded on the day of admission and up to 3 days prior to the date of admission.
