摘要

The aim of this study is to influence of coal-smoke air pollution on the respiratory health in pupils. Provide a gist for the prevention and control of atmospheric pollution. Via using the method of random sampling, we chose two primary schools from coal-smoke polluted areas in urban and two schools from countryside where it is not affected by the coal-smoke pollution, therefore we got total number of 680 primary students as object for this study. Compared to the primary schools children in the countryside, the incidence of respiratory symptoms such as cough, sputum and wheezing, is higher among the children in the urban areas. It is higher significantly in the diagnosis of pneumonia, acute respiratory infection and asthma (P<0.01). Coal-smoke air pollution increases the risk of respiratory symptoms and disease in primary school children, it is the hazard factor of damaging the respiratory symptoms in the children.
