在冬季的几个月里，西雅图大都市区的许多社区受到住宅木材燃烧产生的颗粒物的严重影响。本研究旨在探讨小儿细颗粒物与肺功能的关系。研究对象是326名小学生，其中包括24名哮喘患者，他们居住在一个主要来自住宅木材燃烧的高颗粒物浓度的地区。分别于1988-1989年和1989-1990年冬季采暖季前、采暖季中、采暖季后测定FEV_1和FVC。使用光散射仪器评估细颗粒物。分析光散射和肺功能之间的关系表明，颗粒空气污染的增加与哮喘儿童肺功能的下降有关。σsp每增加10 - 4 m-1，哮喘儿童的FEV 1和FVC平均分别下降34和37 ml。该σ sp增加对应于PM2.5增加20 μg/m3。结论是，细颗粒物从木材燃烧是显着相关的急性呼吸道刺激在年轻的哮喘儿童。
During winter months many neighborhoods in the Seattle metropolitan area are heavily affected by particulate matter from residential wood burning. A study was conducted to investigate the relationship between fine particulate matter and pulmonary function in young children. The subjects were 326 elementary school children, including 24 asthmatics, who lived in an area with high particulate concentrations predominately from residential wood burning. FEV1and FVC were measured before, during and after the 1988–1989 and 1989–1990 winter heating seasons. Fine particulate matter was assessed using a light-scattering instrument. Analysis of the relationship between light scattering and lung function indicated that an increase in particulate air pollution was associated with a decline in asthmatic children*s pulmonary function. FEV1and FVC in the asthmatic children dropped an average of 34 and 37 ml respectively for each l0−4m−1increase in σsp. This σspincrease corresponds to an increase in PM2.5of 20 μg/m3. It is concluded that fine particulate matter from wood burning is significantly associated with acute respiratory irritation in young asthmatic children.
