| Summary: | 碩士 === 國立臺北科技大學 === 環境工程與管理研究所 === 101 === Though petroleum industry is one of the main NMHC source units in Taiwan, the total volum of traffic source NMHC emission, 173,087 tons per year, is bigger than the total volum of petroleum industry NMHC emission, 80,935 tons per year. And since traffic source is closer to the public than industry source, Health risk of residents coused by traffic source NMHC emission would greater than petroleum industry NMHC emission.
In this study, choosing A petroleum industry area and Taipei downtown area as the study sites. Modeling NMHC increasing concentration with AERMOD model and calculate health risk of residents, assessing NMHC pollution impact.
The result shows that NMHC concentration in Taipei downtown is greater than the area around A petroleum industry area NMHC concentration. Concerntration around petroleum industry (average 10.52ppb) is only 1/11 of concertration of Taipei (average 121.30ppb). There is no obviously non-cancer risk on both sites. Maximum HIa around petroleum indutry is6.37×10^(-4), and average is 1.73×10^(-4). Maximum HIc around petroleum industry is2.78×10^(-2), and average is7.55×10^(-3). Maximum HIa in Taipei is 2.69×10^(-2), and average is 4.81×10^(-3). Maximum HIc in Taipei is 6.08×10^(-1), and average is 1.09×10^(-1). Cancer risk of Taipei residents (maximum is 1.03×10^(-3), average is 1.84×10^(-4)) and residents live around A petroleum industry(maximum is 1.52×10^(-4), and average is 4.12×10^(-5)) are not acceptable. Total life expect lost in Taipei is 122,068,616 days, and average is 64.8 days per person. Total life expect lost around petroleum industry is 748,205 days, and average is 7.3 days per person.
