Abstract: |
Objectives: To investigate the effects on human health, and provide some useful evidence in preventing and controlling the atmosphere pollution. Methods: The method of stratified cluster sampling was used in this report. 1832 residents living in 11 communities and 1892 students of 3 middle schools and 5 primary schools were selected to investigate the respiratory symptoms and respiratory diseases. As the control, 943 residents in 5 communities and 917 students of 2 middle schools and 2 primary schools living in the non-contaminated areas (rural areas) in the same city were compared, respectively. Results: The attack rate of residents living in contaminated areas was significantly higher than those living in non-contaminated areas (P value less than 0.01 or 0.05) in aspects of respiratory symptoms and respiratory diseases such as cough, expectoration, pharyngodynia, wheeze, and common cold, pharyngitis, tonsillitis, acute bronchitis and chronic bronchitis, et al. Similarly, the attack rate of students living in contaminated areas was also significantly higher than those living in non-contaminated areas (P value less than 0.01 or 0.05) in aspects of respiratory symptoms and respiratory diseases such as cough, expectoration, pharyngalgia, asthma, and common cold, rhinitis, pharyngitis, tonsillitis and acute bronchitis, et al. However, other symptoms of respiratory disease of the people had no significant difference (P value greater than 0.05). Conclusions: The positive rates of the respiratory symptoms and respiratory diseases were increased which were caused by coal-burning atmospheric pollution. Furthermore, coal-burning atmospheric pollution was one of the main health hazards factors on people’s respiratory system.
