为探讨石油化工企业外环境空气臭氧对儿童健康影响，对大气臭氧及其它污染物进行监测并用整群抽样方法对儿童肺功能做了测定。结果显示臭氧最大１小时平均浓度接近国家空气质量标准（０．１２ｍｇ／ｍ３），污染区儿童肺功能（ＭＭＦ和ＦＥ７５）低于对照区，差异有显著性。靠近石油化工厂的小学生呼吸道疾病发病率亦较其他小学高。提示该石化厂周围存在一个相对高臭氧浓度的区域。暴露于该空气环境的儿童肺功能轻度降低。
In order to explore the impact of air ozone on the health of children in petrochemical enterprises, the atmospheric ozone and other pollutants were monitored and the lung function of children was determined by cluster sampling method. The results showed that the maximum average concentration of ozone in one hour was close to the national air quality standard (0.12mg / m3), and the lung function (MMF and FE75) of children in the contaminated area was lower than that in the control area. The difference was significant. Primary school students near the petrochemical plant also have higher incidence of respiratory diseases than other primary schools. Suggesting that there is a region of relatively high ozone concentration around the petrochemical plant. Children exposed to this air environment had a mild decrease in lung function.
