The authors investigate the effect of CO pollution Caused by two different heating wavi onpupil’s COHb concentration and immunological competence. The results show that CO pollution restrains the immunity functions of the nonspecific and specific body fluid.The salivary lysozyme and immune globulin concentration are regarded as a sensitive sign which reflects a first- stage of danger of air pollution.

Objectives To explore a better amending method for a set of correlated time series with heavy missing data and its application to monitoring data on environment pollution.Methods A model of Simultaneous Linear Equations with ARMA Error is proposed for iterative estimation of missing values.Simulation study is performed on the basis of an AR(1)model with input series and applied study is performed on th basis of a real montoring data set on CO-pollution respectively.The results are compared with those estimated wih three usually used apporaches,Multivariate Linear Regression,Simple ARIMA and interpolation by cubic spline in terms of statistical property.Programming is performed with statistical software SAS.Results The iterative approach based on the model of Simultaneous Linear Equations with ARMA Error is better than other three approaches significantly.Conclusion The amending method proposed can be used to estimate the missed values of a set of multi-dimensional time series with heavy missing,and apply to relevant monitoring data in real life.
