大气污染与儿童肺功能的典型相关分析

Canonical correlation analysis of air pollution with children's lung function

在 1 994～ 1 996年间 ,对污染点和对照点 (相对清洁点 )同时进行了大气污染 (气溶胶 ,二氧化硫等 )和儿童肺功能 (FVC,FEV1 ,FEF2 5～ 75 等 )的测定。对它们之间的关系进行了典型相关分析 ,其结果是肺功能指标和大气污染物呈负相关。统计分析提示污染点与对照点儿童肺功能的差别主要是由于大气污染 (气溶胶 )造成的 ,特别是 PM2 .5 的细粒子造成的。

From 1994 to 1996, measurements for air pollution (aerosol and SO 2, etc ,) and children's lung function (FVC, FEV, and FEF 25～75 ) were carried out simultaneously in a polluted site and a relative clean site Canonical correlation analysis was done for the relationship between them; the result is that there exists a negative correlation between lung function of children and air pollutant It is clear that the difference between lung function in polluted site and clean site is mainly due to the air pollution (aerosol), especially the fine particulate PM 2 5
