许多研究报告了空气中颗粒物与从症状到死亡的一系列呼吸系统结果之间的关联。目前的注意力集中在这些颗粒的特性负责的不利健康影响。我们重新分析了最近三项纵向日记研究，以检查细颗粒和粗颗粒对学龄儿童呼吸道症状和呼气峰流量的相对贡献。在哈佛六城市日记研究中，双污染物模型中的下呼吸道症状与细颗粒物的四分位距增量相关[（对于15 μ g/m3的颗粒物（PM）
Numerous studies have reported associations between airborne particles and a range of respiratory outcomes from symptoms to mortality. Current attention has been focused on the characteristics of these particles responsible for the adverse health effects. We have reanalyzed three recent longitudinal diary studies to examine the relative contributions of fine and coarse particles on respiratory symptoms and peak expiratory flow in schoolchildren. In the Harvard Six Cities Diary Study, lower respiratory symptoms in a two-pollutant model were associated with an interquartile range increment in fine particles [(for 15 mu g/m(3) particulate matter (PM)
