摘要
对承德市空气污染和学生呼出气最大流速(PEF)进行了研究。空气监测表明,承德市冬季除NO_2外,SO_2、TSP和CO浓度燃煤区高于集中供热区。PEF测试发现,采暖后期燃煤组学生PEF与采暖前期相比明显降低,与供热组比较,差异显著。供热组的PEF值采暖前后变化不大。研究认为,空气污染使PEF值明显降低,测试PEF为早期显示空气污染对人体肺功能影响的研究提供了新方法。
he paper reported a research on Air pollution in chengde of china and peak Explratory flow(PEF)of pupits,Montoing restrls for Air showed that concentra-tions of SO2,TSP and CO higher in coal-bunning distriot than in cdntralized heat supply distriot,exocpt for NO2, in chengde' Winter.Monitoning nesults for PEF showed that PEF of pupills in coal-bunning grow sigrilicanty lower affter winter than befor winter.The grow in coal-bunning com-pane with the growin heat supply, differenes was obxi-ons. In the heat suply grow, dterges of between befor winter and affter winter was very small.the project be-lieved that Air pollutions could neduced PEF.Analyses to PEF Should supply a new measure to pulnomary funtions.
