In the province of Quebec, ragweed pollen is the principal allergen causing allergic rhinitis. The present study examines the relationship between the concentration of ragweed pollen and the prevalence of allergic rhinitis in August in the populations of two municipalities in the Laurentide area, a region on the northern limit of distribution of ragweed. The concentration of ragweed pollen was measured with a Burkhard sampler. The prevalence of allergic rhinitis was simultaneously measured by a telephone survey which was addressed to a random sample of 500 households in the two municipalities. The results showed a significant difference in the prevalence rate of allergic rhinitis in the population of the two municipalities (3.77% and 7.22%) exposed to significantly different pollen levels. Interventions aimed at lowering the pollen concentrations could lower the prevalence rate of allergic rhinitis in August.
在魁北克省，豚草花粉是引发过敏性鼻炎的主要过敏原。本研究考察了豚草花粉浓度与位于豚草分布北界的洛朗代地区两个市镇8月份人群中过敏性鼻炎患病率之间的关系。豚草花粉浓度采用伯克哈德采样器进行测量。同时，通过电话调查对两个市镇的500户随机抽样家庭测量过敏性鼻炎的患病率。结果显示，暴露于显著不同花粉水平的两个市镇人群中，过敏性鼻炎患病率存在显著差异（分别为3.77%和7.22%）。旨在降低花粉浓度的干预措施可降低8月份过敏性鼻炎的患病率。
