石油化工大气污染对儿童呼吸功能影响研究

Research on the impact of air pollution of petrochemical plant to childre n's pulmonary function.

本文研究石油化工大气污染对儿童肺功能影响，选择与石化厂不同距离的４所小学的９～１０岁儿童为观察对象，对大气污染水平与儿童呼吸功能进行动态观察，按不同季节监测大气中各种污染物并同时测定儿童呼吸功能，对影响儿童肺功能的其他因素进行多元回归分析。结果显示，石化厂周围大气污染物浓度随季节而变化；儿童肺功能与大气污染水平呈一定负相关，女童较男童敏感。呼吸功能各指标中以ＦＶＣ、ＰＥＦＲ和ＭＭＴ为敏感，提示在石化厂一定距离范围内大气污染对儿童肺功能已产生影响。

To study the impact of air pollution of petrochemical plant to the children's pulmonary function,9～10 years old students from four primary school which were in different distance to the petrochemical plant were selected as study population.We took dynamic observation on the air pollution levels and the children's pulmonary function.Both the pollutants in the air and the children's pulmonary function were measured in different seasons,By multiple regression,other factors which can impact children's pulmonary function were analyzed.The results showed that,the air pollutants concentrations around the petrochemical plant changed with the seasons'changing,the children's pulmonary function were certain inverse related to the air pollutants levels,and girls were more vulnerable than boys.Among the pulmonary functions markers,FVC, PEFR and MMT were the sensitive markers,it indicated that in certain distance from the petrochemical plant,the children's pulmonary function had been affected by the air pollution.
