Study On Traffic Pollution Of City And Adult Respiratory System Response

With the economy growth and the dilation urbanizing, the traffic pollution caused by traffic jams and motor vehicle gas gradually gravely, which affects not only the urban environment quality, but also the respiratory system of the residents along roads.Taking Tianjin as an example, four representative traffic intersections (Hai Guang-si,Wang Ding-di Overpass,Huayuanyashi Road,Yang Liu-qing Square) and the section of University town on Jin-jing road were selected as the monitoring station. The concentration of main traffic pollutant NOX (nitrogen dioxide and nitric oxide) and SO2 in the air was detected with the method of monitoring pollution spots. The result showed that, the API of four monitoring stations was higher than that proclaimed by authority department and the NOX pollution of Hai Guang-si was more serious. The concentration of SO2 maintained steady, while that of NO and NO2 fluctuated wildly. It may be related to the diffuse constrained factors of emissions. The correlation between the concentration in different time and traffic flux had no significant difference, because the pollutant concentration was restricted with ( wind speed,temperature,traffic flux and hypsography ). The concentration of air pollution was changed as the influence of auto tail gas in Jin-jing road. Commonly, with the vehicle flux increased the concentration of Nitrogen oxides enhanced. But vehicle flux has small infection to the concentration of Sulfur dioxide. As the distance raised, the concentration of Nitrogen oxides was reduced.In addition, through the investigation and analysis of adult respiratory system disease incidence about serious traffic pollution area-Hai Guangsi and the better air quality area-Xi Qing University town in Tianjin, we found that traffic pollution has a direct effect on the high incidence of respiratory system disease. On this basis, it has a high correlation between the respiratory system disease incidence and the pollutants. Also, the main pollution factor of respiratory conditions contains cold cough, sputum, asthma, bronchitis and pneumonia is different.
