| Summary: | 碩士 === 國立雲林科技大學 === 環境與安全衛生工程系 === 102 === In this study, from 2004 to 2013 Southwest Air Quality District, totaling 11 air quality monitoring stations of the suspended particles (PM10 and PM2.5) for the scope of the study, combined with meteorological data than the concentration of suspended particles in the discussion of Taiwan in recent years, Southwest Region and air quality trends. The results found that over the past decade PM10 and PM2.5 concentrations were slightly decreased, showing the Taiwan region for air quality improvement and increased attention. Concentration below which the summer and winter, due to climatic factors such as wind direction, rainfall and other effects of the atmospheric concentration of suspended particles, the proposed industrial activity may be due to the type or intensity of climatic factors fine-tuning in order to facilitate the maintenance of air quality. The concentration found in the analysis, PM10 exceeded the number of hours to a maximum of Chiayi County, Chiayi City, the largest number of places PM2.5 exceeded, the display location great impact on the environment, while sources upwind contribution should increase attention. In addition, this study Yunlin County to investigate the impact of climate conditions studied, analyzed and summarized resulting in a high reflux and northeast monsoon climate patterns up to two higher concentrations of suspended particulate patterns. In the northeast monsoon and the sea breeze was strongly under the double impact, the impact of the dust of the estimated range of Jhuoshuei River near Chiayi County. Air quality trend analysis in this study can be obtained nearly ten regional type pollutants such as particulate matter pollution control should be strengthened, in response to the special climatic patterns of climate change should establish contingency as to safeguard public health and safety.
