【摘要】 通过整群抽样方法,对所选定的774人进行鼻咽部3项、血液10～13项、肺功能9项,共25个分析项目的分析测试,以污染区与对照区人群比较,t 或 q 检验,结果鼻咽部指标差异有显著性意义的9项次,占该项次的75.0%;血液指标差异有显著性的35项次,占该项次的59.3%;配对研究中肺功能指标差异有显著性意义的12项次,占该项次的33.3%,其中大气道占41.7%,小气道占58.3%.表明污染区人群鼻咽、血液、肺功能等指标均不同程度地发生变化.更多还原

【Abstract】 With the sample method,analysis of 3 nose & throat items,10-13 blood items and 9 lung function items among the chosen 774 persons,and comparing people in pollution district with those in compared district,we finish t or q examinations. The resluts indicate that there are 9 obviously difference indices in nose & throat section,comprising of 75% of the whole item-times;there are 35 obviously diffe- rence indices in blood,comprising of 59.3% of the whole item-times;there are 12 obviously difference indices in lung function,comprising of 33.3% of the whole item-times;among them large respiratory track takes up 41.7%,and small respir- atory track takes up 58.3%.The conclusion ind cates that the indices of nose & throat,blood and lung function etc of people in polluted district have been chan- ged to greater or less extent.更多还原
