宁夏某市大气污染对健康影响的研究

Study of the Effect of Atmospheric Pollution on Human Health in a City of Ningxia

为评价大气污染对健康影响尤其是低浓度早期危害,分别在居住区、工业区、商业区和清洁区设点监测SO2、NOx、TSP,同时在各区选7～14岁小学生检查眼、耳鼻喉科疾病,免疫功能,唾液AP T1/2e测定。结果表明生活在各污染区儿童上呼吸道疾病检出率和AR阳性反应率均高于对照区（P【0.05）;唾液溶菌酶低于清洁区（P【0.01）;唾液中AP T1/2e缩短,与TSP的相关系数r=-0.957（P【0.025）。

In order to evaluate the early harm of atmospheric pollution, especially low concentrated pollutants to human health, sulfur dioxide (SO_2)nitrogen oxides (NOx) and total suspended particulates (TSP) were surveillanced in the districts of residential, industrial, commercial and clean areas respectively, and the diseases of ear-nose-throat, immune function,and AP T l/2~e in school children (7—14 years old) were examined at the same time. The results showed that prevalence of eye and respiratory diseases and the positive reaction of AR in pupils in those polluted areas were significantly higher than those in clean areas (P<0.05). Saliva Lysozyme concentration of pupils in polluted areas were significantly lower than that in clean areas (P<0.01). The AP T1/2~e in saliva was shortened the correlation coefficient between AP T1/2~e and TSP was -0.957 (P<0.025). It indicated that the AHH activity was increased.
