| Summary: | 碩士 === 中山醫學大學 === 醫療產業科技管理學系碩士班 === 106 === The sick building syndrome caused by various air pollutants always damages our health. Public transportation is the place where people stay the longest except for inside of the building. Therefore, this study aimed at Taiwan public transportation, including Taiwan high-speed rail and Taiwan Railway, bus and Mass Rapid Transit (MRT). Performed air detections for CO2, CO, Particulate Matter (PM), HCHO, O3 and VOC. One-way analysis of variance (ANOVA), T test (Student t-test) and Pearson Product-Moment Correlation Coefficient were used to analyze the measured data.
The results of the study showed that high-speed rail detection has higher PM on platforms and commercial vehicles, while high-speed rails also have higher CO2 concentrations in peak-time compartments with more people. And the concentration of PM and CO2 are the highest in railway station, the air quality of Tze-Chiang Limited Express is the worst. The detection results of MRT show that the highest concentration of PM in the hall and the high number of people would produce poor air quality, such as the Tamsui-Xinyi Line and the Wenhu Line in Taipei MRT, and so on. The detection results of bus show that the concentration of PM in bus stops is the highest, and the concentration of CO2 in bus is higher. The number of suspended particulates in high-speed rail, Taiwan Railway, MRT and bus is affected by the number of people in the car.
This research suggested that air cleaning system should be set up in public transportation and control panel should be set up to adjust the flow rate so that the air can be filtered effectively. The high efficiency filter (HEPA filter) can be used to filter air pollutants. In addition, as the concentration of suspended particulates in conveyors is closely related to the number of passengers. Also, suggested that a platform compartment monitoring system should be adopted to balance the number of passengers in each compartment, so as to avoid causing poor air quality in individual compartments. The study also suggests that the public should enhance their awareness and behavior of public transport air quality hazards. According to air quality conditions of public transport to protect self.
