摘　　要：目的　分析 1999年以来郑州市大气单因子污染指数 (pi)与儿童上呼吸道感染门诊就诊人数 (Y)之间的相关性 ,并确定大气污染物中的主要致病污染物。方法　用化学分析法测定大气中各主要污染物含量 ,用单纯整群抽样法进行Y的调查 ,用多元线性回归和多元逐步回归分析法分析pi和Y的相关性。结果 :分析提示 1999年大气污染物中SO2 与Y有密切关系。PSO2 与Y的线性回归方程式为 :Y =2 94 1.3+4818.5PSO2 。结论 :郑州市大气污染物中SO2 为主要致病 (上呼吸道感染 )因子。TSP、NOX 与SO2Objective To study the correlation between air single pollution factor PI and Y of the infection of the upper respiratory tract in Zhengzhou city, 1999,and decide its main pathogenic polluted substances. Methods Using the methods of chemical analysis to determine each polluted substance in the air. Using the simple hole sample method to investigate Y. Using pluralism linear regression and pluralism progressive regression to analyse the relationship between PI and Y.Results SO 2 and Y in air pollution has closed relationship in Zhengzhou city in 1999. There was a coordinated relationslip between TSP and NO X. P SO2 and Y's linear regression equation is Y=2941.3+4818.5 P SO2 .Conclusions In the polluted air substances of Zhengzhou city SO 2 is the main pathogenic factor.TSP,NO x and SO 2 have coordinated pathogenic action.
