RESUMO
AIMS: To determine the health impacts of smoke and the effectiveness of public health advisories during a severe bushfire smoke event in Albury, NSW. METHODS: The NSW Department of Environment and Climate Change provided PM(10) data. A computer-assisted telephone survey using random digit dialling was conducted following the smoke event to assess health impacts and the effectiveness of advisories. RESULTS: The smoke event lasted 38 days. The maximum daily PM(10) level was 415 microg/m(3). Public health advisories were based on alerts for air pollution issued by NSW Department of Health. From the survey, a total of 389 interviews were available for analysis. At least one health effect of the smoke was reported by 70% of respondents and 5% reported seeking medical treatment. Over 74% reported seeing, hearing or reading the health advisories. Behaviour change was significantly greater in this group (odds ratio = 2.74; 95% confidence interval 1.50-5.02). CONCLUSION: High rates of health effects may be experienced by populations exposed to bushfire smoke pollution. Public health advisories can support behaviour change to reduce exposure to bushfire smoke.
