我们研究了植被火灾产生的直径 < 10 和 < 2.5 微米的颗粒物 (PM10 和 PM2.5) 与 251 名患有哮喘的成人和儿童在 7 个月内的日常健康结果之间的关系。使用针对潜在环境混杂因素、自相关、周末和假期进行调整的广义估计方程对数据进行分析。 PM10的范围为2.6-43.3 μg m(-3)，与哮喘症状的发作、开始口服类固醇药物、平均每日症状计数和平均每日缓解药物剂量显着相关。 PM2.5 也有类似的结果。没有发现与哮喘发作、医疗保健就诊人数增加或缺课/缺勤等更严重后果之间存在关联。这些结果有助于填补关于为控制燃料负荷而故意进行景观燃烧的较低污染水平对人口健康影响的证据，与记录更详细的更强烈、更严重污染的野火风险之间的差距。
We examined the relationship between particulate matter (PM) < 10 and < 2.5 microns in diameter (PM10 and PM2.5) generated by vegetation fires and daily health outcomes in 251 adults and children with asthma over a 7-month period. Data were analysed using generalized estimating equations adjusted for potential environmental confounders, autocorrelation, weekends and holidays. PM10 ranged from 2.6-43.3 mu g m(-3) and was significantly associated with onset of asthma symptoms, commencing oral steroid medication, the mean daily symptom count and the mean daily dose of reliever medication. Similar results were found for PM2.5. No associations were found with the more severe outcomes of asthma attacks, increased health care attendances or missed school/work days. These results help fill a gap in the evidence about the population health impacts of lower levels of pollution characteristic of deliberate landscape burning to control fuel loads versus the better documented risks of more intense and severely polluting wildfires.
