摘要
目的探讨空气污染程度不同地区小学生肺功能之间的差异。方法收集空气相对轻重污染区2006~2008年大气SO2、NO2、PM10和CO的日监测值,在污染轻重区分别设点每月进行PM2.5的监测,在大气监测点周围3km范围内各选择1所600人以上的学校进行小学生肺功能检查。结果①空气相对重污染区(南山区)空气SO2、NO2、CO、PM10和PM2.5平均浓度均高于空气相对轻污染区(龙岗区),分别为0.0285mg/m3与0.0227mg/m3,0.0649mg/m3与0.0473mg/m3,2.278mg/m3与1.478mg/m3,0.0724mg/m3与0.0713mg/m3,0.0665mg/m3与0.0524mg/m3,除PM10外,差异均有显著性(P<0.05)。②小学生肺功能主要指标(VC、VC%、FVC、FVC%、MVV、MVV%、FEV1.0、FEV1.0/FVC、PEF、PEF%、FEF25、FEF50和FEF75)随着年龄的增长而增高。同年级小学生肺功能比较,南山区小学生肺功能主要指标值高于龙岗区,主要指标差异均有显著性(P<0.05)。结论空气污染对小学生肺功能可能有影响。
Objective To explore the changes of lung function of primary students living in the regions of different air pollution.Methods Nanshan District and Longgang District were decided respectively as a relatively heavy air pollution region and as a relatively light air pollution region in Shenzhen according to their air pollutant concentrations.The daily monitoring values on atmospheric SO2 ,NO2 ,PM10 and CO from 2006 to 2008 in the two districts were collected.PM2.5 monthly monitoring was started in Jan.2008.Pulmonary functions of primary students were performed in the two schools within the scope of the surrounding 3km of the PM2.5 monitoring points.Results Average concentrations of atmospheric SO2 ,NO2 ,CO,PM10 and PM2.5 in Nanshan District were more high than those in Longgang District.Their concentrations were 0.0285 mg /m^3 vs 0.0227 mg /m^3 ,0.0649 mg /m^3 vs 0.0473 mg /m^3 ,2.278 mg /m^3 vs 1.478 mg /m^3 ,0.0724 mg /m^3 vs 0.0713 mg /m^3 and 0.0665 mg /m^3 vs 0.0524 mg /m^3 (P〈0.05) respectively except PM10.Levels of the key indicators of lung function (VC,VC% ,FVC,FVC% , MVV,MVV% ,FEV1.0,FEV1.0 /FVC,PEF,PEF% ,FEF25 ,FEF50 and FEF75 ) increased with ages in the primary students.Means of the most indicators in Nanshan District were higher than those in primary students in Longgang District.Significant difference existed in the same grade of students on lung function in the two regions (P〈0.05).Conclusion Air pollution could affect pulmonary function of primary students.
