Relationship between Air Pollution and Child Pulmonary Function in China / 环境与健康杂志

ABSTRACT

Objective To describe the relationship between ambient air pollutants(TSP,SO2,NOx) and the level of children’s lung function (FVC,FEV1,MMEF) in China. Methods The papers on ambient air pollution and children lung function published from 1985 to 2006 were collected and 11 of them were selected according to the following criteria children aged 7-15; local air quality monitoring results were reported; strict quality control were taken when testing children lung function; the results were expressed by the average of measure. Results The selected papers included the results of 7 cities in China. Among them,the result of 6 cities showed that the levels of children lung function were significantly lower in the heavy air pollution areas compared with that in the light pollution areas. According to the papers,the average levels of ambient air TSP were in the range of 0.084 mg/m3-0.835 mg/m3,SO2(cSO2) were 0.013 mg/m3-0.929 mg/m3,NOx were 0.044 mg/m3-0.229 mg/m3,there was a significant negative correlation between the levels of TSP and SO2 and children FVC and FEV1,as well as the levels of NOx and children MMEF,the correlation coefficients were as follows,-0.797(t=-4.384,P=0.001) between TSP and FVC,-0.693(t=-4.190,P
