为探讨天津市工业区大气污染对儿童健康的影响，于１９９５年１０～１１月对天津市某工业区（污染区）与对照区进行了环境流行病学调查。调查对象为７～１２岁儿童（污染区９０２人，对照区９１８人）。结果表明污染区大气ＳＯ２、ＮＯｘ、ＴＳＰ、ＣＯ浓度均显著高于对照区（Ｐ＜０．０５或Ｐ＜０．０１）；污染区儿童呼吸系统疾病、过敏性疾病患病率均显著高于对照区（Ｐ＜０．００５）；大气污染使儿童肺活量明显降低，差异有显著性（Ｐ＜０．０５）；污染区儿童免疫指标如（唾液溶菌酶活性、ＳＩｇＡ含量）、鼻粘膜细菌总数及溶血性链球菌数目与对照区比差异均有显著性（Ｐ＜０．０５）。提示污染区大气污染已对儿童健康状况产生明显危害
To investigate the impact of industrial pollution in Tianjin on children’s health, an environmental epidemiological survey was conducted in an industrial area (pollution area) and a control area in Tianjin from October to November in 1995. The respondents were children aged 7-12 years (902 contaminated areas and 918 controls). The results showed that the concentrations of SO2, NOx, TSP and CO in the polluted area were significantly higher than those in the control area (P <0.05 or P <0.01). The prevalence of respiratory diseases and allergic diseases in children in the polluted area were significantly higher than (P <0.05). The air pollution reduced the lung capacity of children significantly (P <0.05). The immune indexes such as (salivary lysozyme activity and SIgA content), the total number of nasal mucosa And the number of hemolytic streptococcus and control area were significantly different (P <0.05). Prompted air pollution in the polluted area has a significant health hazard of children
