工业区大气污染对儿童生长发育影响的研究

The Study of Air Pollution's Insfluence on Children Grow and Develop Targetin Industry Area

为探讨天津市工业区大气污染对儿童生长发育的影响，为大气环境综合治理提供卫生学依据，于１９９５ 年１０ ～１１月对天津市某工业区与对照区进行了环境流行病学调查。调查对象为７ ～１２ 岁学龄儿童，污染区９０２ 人，对照区９１８ 人。结果表明工业污染区中 Ｓ Ｏ２ 、 Ｎ Ｏｘ 、 Ｔ Ｓ Ｐ、 Ｃ Ｏ 超标率分别达５５５５ ％ 、３４４５ ％ 、９３７８ ％ 、３２２５ ％ ，分别是对照区的４５５倍、４１５ 倍、１３０ 倍、１５３ 倍。大气污染使儿童生长发育指标：身高、体重、胸围、肺活量有明显降低（ Ｐ＜ ００５） 、（ Ｐ＜００１） 。提示工业区大气污染已对儿童健康状况产生明显危害。

In order to study air pollutions on children's grow and develop tardget in tianjin industry Area,and provide hygiene basis for tackling air environment epidemiology investigation during Oct Nov.,1995 in Tianjin certain industry Area and relevant comparison Area.The object is school children age 7～12.In polluted Area are 902 childern and comparison area are 918.The results show taht in polluted area the exceed standard rate of SO 2、NO x、TSP、CO are 55 55%、34 45%、93 78%、32 25% respecively.Correspondingly in comparison area are4 55、4 15、1 30、1 53 times as that in polluted area respectively.The air polution has great dcereace to children grow and develop target:with,weight,across chest,vital capacity.These targets have remarkable discrpancy(P<0 05),(P<0 01).These results indicated that air pollution had been obviously detrimental to children's health in this area.
