工業都會區之環境大氣有害空氣污染物濃度特徵

有害空氣污染物（Hazardous air pollutants, HAPs）因具有急毒性，且與居民健康直接相關，已成為世界先進國家管制重要項目。HAPs來源可大致區分為固定污染源與移動污染源，本研究以臨海工業區為範疇，針對柴油車密集區監測HAPs，了解移動污染源柴油車HAPs環境濃度，並蒐集臨海工業區特殊性工業區測站監測數據，解析工業都會區之HAPs物種特徵。於柴油車密集區利用離線（Off-line）與線上（On-line）方法，獲得HAPs環境濃度。離線檢測結果顯示監測所得HAPs物種主要為醛酮類（甲醛、乙醛），另測得壬烷、三甲基苯較於都會區移動污染源高，顯示該地區排放源確為柴油車貢獻。比較臨海工業區之工業測站以及柴油車密集區之監測HAPs物種結果，於柴油車密集區測得較高濃度甲醛、乙醛（5.26～17.4 ppm），苯及乙苯則於工業區測站及柴油車密集區皆有測得；而重金屬物種不論固定源或柴油車監測結果皆低。此外，於柴油車密集區域測得非包括1,2-二氯乙烷、氯乙烯、1,4-二氯苯、丁二烯等非柴油車排放物種，顯示柴油車密集區域仍會受到固定源工廠排放HAPs影響。為了解含氯物種以及丁二烯排放源，本研究以線上連續監測技術搭配風速與風向驗證，結果顯示可能來源為測站西北方之前鎮碼頭儲槽區。

Hazardous air pollutants (HAPs) have acute toxicity and are directly related to the health of residents. They have become an important item of control in the world. The sources of HAPs including stationary source and mobile sources. This study monitors the HAPs concentration in the dense diesel vehicles areas (Kaohsiung Xiaogang District), and use stationary monitor site data in the Linhai Industrial Park to analyze the differences in HAPs concentration between stationary monitor site and diesel vehicle areas. This study uses off-line and online on-line methods to evaluate the ambient concentration of HAPs emitted by diesel vehicles. The off-line test results show that the main pollutants emitted by diesel vehicles are mainly carbonyls (formaldehyde, acetaldehyde), and the measured nonane and trimethylbenzene are higher than the mobile pollution sources in the metropolitan area, indicating that monitor concentration of HAPs in dense diesel vehicles areas is really from diesel vehicles. Comparing the results of monitoring HAPs species at industrial monitoring stations and dense diesel vehicles areas, diesel vehicles mainly contribute formaldehyde and acetaldehyde species (5.26-17.4 ppm), stationary sources and diesel vehicles will all contribute benzene and ethylbenzene species. Concentration of heavy metal species in stationary monitor site and dense diesel vehicles areas are very low. In addition, non-diesel vehicle emission species measured in dense diesel vehicles areas, including 1,2-dichloroethane, vinyl chloride, 1,4-dichlorobenzene, and butadiene, indicate that pollutants measured in dense diesel vehicles areas will still be affected by HAPs emitted by stationary source. In order to understand chlorine-containing species and butadiene emission sources, this study used online monitoring methods and wind speed and wind direction to verify emission sources. The results showed that the sources from northwest of the Storage tank.
