| Summary: | 碩士 === 國立屏東科技大學 === 環境工程與科學系所 === 100 === The occurrence of sand storms in Asia increased year by year, Occurred five times by the 1950s, 1960s, occurred eight times, 13 times 1970's, 80'shappened 14 times, 90 occurred 23 times, to the year 2000 that is 12 times, and the result of human economic activity generated by human factors on the damage caused to the environment more and more serious, resulting in the intensity of dust storms in Asia is also growing, and the frequency it is growing frequently, making it a cross international air pollution has also become an international disaster, and a serious natural disaster issues. Although Taiwan is located in the periphery of the East Asian sand storms, but in recent years, dust storms affect Taiwan's air quality has become increasingly frequent, and the growing strength of the trend, for example, nearly all 2009 and 2010 due to strong intensity of Asian sand storms, laden with a large number of suspended particles and affect Taiwan's air quality, the Asian sand storms generated by air pollution has also become a subject of analysis to be studied.
Analysis from 2005 to 2010 six stations Guanyin, Shalu, Tainan, LinYuan , Ilan and Hualien impact of sand storms on the incident in Taiwan, the study shows that the intensity of sand storms in recent years, Asia has growing tendency, especially in the April 25, 2009 and March 21, 2010 are the most severe dust storms in recent years, incidents, One in 21 March 2010 the sand storms, the air pollution index (PSI) values are> 500 harmful to human health effects. The results found in Tainan and Linyuan local air pollution monitoring stations than the other stations the situation so serious impact on Taiwan in the sand storms,its concentration of suspended particulate matter (PM10) have a more significant increase in cases, and speed in the analysis of the , and found that after Tainan and Linyuan stations, its speed has slowed the trend, so there remain as happens now, and because of a serious problem with local air pollution caused by suspended sand storms particles, so the air pollution index level of sensitivity is often poor populations to harmful effects. Sand storms occurred in the number of cases compared with the number of respiratory disease treatment, the results show that the number of visits and the number of sand storm events has its relevance, which from 2007 to 2010 was most apparent when the 2007 sand storm event four times, the number of visits 15,509,114, while the impact of sand storms events in 2008 only 1 times, the number of visits 15,280,418 people, 220000 people more than 2008 young of more, the 2009 and 2010 due to more severe sand storms, the number of visits of up to 15,769,685 and 15,759,153 class, compared to the previous two years, the number of visits increased number of respiratory diseases.
