【摘要】 目的研究室内燃煤与大气污染对儿童肺功能的交互作用影响。方法1995-1996年间在中国4城市的城区和郊区的8所小学对6～12岁的儿童进行肺功能的队列测试,每年分冷、暖两季进行。通过3步回归过程进行统计分析。结果室外空气颗粒物与儿童第1秒最大呼气量(FEV1)、用力肺活量(FVC)和FEV1/FVC都有显著的负相关关系。家庭燃煤与TSP对FEV1和FVC有较显著的交互作用。家庭燃煤与PM10对肺功能的交互作用较弱,但有加重颗粒物对肺功能产生不利影响的趋势。未发现室内燃煤与SO2和NOx对肺功能有显著的交互影响作用。结论家庭燃煤这种室内污染因素加重了环境空气颗粒物污染,特别是TSP对儿童肺功能的不利影响。更多还原

【Abstract】 Objective To study the interaction effect of indoor coal consumption and outdoor air pollution on children’s lung function. Methods During 1995-1996, a cohort study on lung function measurements of children aged 6-12 was carried out in urban and suburban schools in 4 Chinese cities (twice a year in both warm and cold parts of the years). A so,called three,stage regression was used as statistic method. Results In the present paper it had been seen that the concentration of ambient air particles was negatively related to children’s FEV1, FVC and FEV1/FVC, TSP and indoor coal consumption showed a significant interaction on children’s lung function. There was only a weak interaction between indoor coal consumption and PM10 , but the results still showed a clue that indoor coal usage might aggravate the adverse impact of air particles on children’s lung function. However, there were no significant interactive relations had been found for SO2 or NOx. Conclusion Indoor coal burning can aggravate the effects of outdoor particle pollution, especially TSP, on children’s lung function.更多还原
