碩士 === 大仁科技大學 === 環境管理研究所 === 102 === In recent years, more emphasis has been put on environmental protection and the promotion of health awareness. Many investigations of air pollution and the impact of the air pollution concentrations on human health have gradually received extensive discussions. In order to understand the impacts of total volatile organic compounds (hereinafter referred to as TVOC) in the industrial area on its neighboring schools and residences, this study selects four sites in the industrial area in the south and its neighboring elementary schools and residences. The climate in winter is relatively stable in southern Taiwan. In order to avoid students at schools and factories in operation, this study uses a portable instrument ppbRAE3000 to obtain samples on the air quality only from Monday to Friday during the winter vacation. The detections of air quality are conducted on each site for three time a day (7:00am-8:00am; 10:00am-11:00am; 15:00pm-16:00pm). The results show that the average concentrations of the TVOC (measured in ppb) in the industrial area, Elementary School A, Elementary School B, Elementary School C, Residence 1, and Residence 2 as follows. In the morning (1523.29 ± 933.38,863.47 ± 62.82,488.18 ± 16.84 , 424.85 ± 31.05,831.29 ± 183.158,725.79 ± 285.65); at noon (1035.52 ± 1281.91,484.64 ± 32.15,462.92 ± 15.18,266.70 ± 14.28,711.89 ± 189.64,515.03 ± 58.91); in the afternoon (733.22 ± 344.77,410.56 ± 17.05 , 496.12 ± 56.06,268.48 ± 22.75,355.61 ± 20.84,412.27 ± 40.97). The measured data show that, except for Elementary School B that is heavily influenced by the Taiwan Provincial Highway No. 1, the TVOC concentrations on other sites are highest in the morning, second highest at noon, and lowest in the afternoon. Elementary School C which is most distant away from the industrial area has the lowest TVOC concentrations. Residence 2 which is most distant away from the industrial area has TVOC concentrations lower than Residence 1 has. The results show that the distance from the industrial area is main factor that influences the TVOC concentrations in the air. Therefore, we suggest that some TVOC detection stations be built in the industrial area in the south and that the evacuation routes be planned for school children when the TVOC is detected to exceed normal ranges of concentrations.
