摘要:	本研究利用揮發性有機物（Volatile organic compounds，VOCs）自動採樣設備，24小時監測某工業區周界揮發性有機物濃度、風速、風向、溫度及濕度等項目，同時當VOCs監測濃度較高時，自動觸發鋼瓶採樣分析污染物濃度，並運用異味活性值(Odor activity value，OAV)及權重分析結果，評估異味污染物來源及其污染指紋，期進一步勾稽比對異味污染來源，並作為環保機關稽查管制之參考依據。本研究以苗栗縣高異味污染陳情之頭份工業區為研究對象，該工業區有高異味污染之虞的工廠，計有H公司頭份廠(塑膠品製造業)、C公司頭份廠(化學材料製造業)、F公司(紡織業)、T公司頭份廠(化學材料製造業)、O公司(化學材料製造業)、S公司(化學材料製造業)及V公司(化學材料製造業)等7家。研究結果顯示，監測期間共觸發5次自動採樣，分析結果有62種污染物，主要污染物為甲苯(9.88 ppb )、間對-二甲苯(2.64 ppb )、順式-1,2-二氯乙烯(2.56 ppb )、乙烷(2.26 ppb )及氯乙烯(1.92 ppb )等污染物，係屬該工業區之污染指紋。另以異味活性值分析之結果可知，甲苯（OAV = 0.706）、間對-二甲苯（OAV = 0.033）、正丙苯（OAV = 0.023）、異丙苯（OAV = 0.018）及異丁醛（OAV = 0.014）有較高之異味情形，可視為該工業區之異味污染指紋。另根據權重分析比對結果，氯乙烯、甲苯、苯、二氯甲烷及丙烯腈等污染物，為該工業區應優先管制之污染物。比對相關工廠原物料清冊結果，H公司頭份廠應加強管制甲苯及氯乙烯，C公司頭份廠及T公司頭份廠亦須加強管制甲苯，至於二氯甲烷及丙烯腈等污染物尚無比對出對應之污染來源。根據本研究初步建立監測採樣之方法，應可提供後續環保機關對於空氣污染物管制工作之參考，並藉以提升稽查管制之效能。 ;This study investigates that monitoring the concentrations of volatile organic compounds(VOCs), wind speed, wind direction, temperature and humidity in a industrial area for 24 hours by volatile organic compounds automatic sampling equipment. When the VOCs monitoring concentration is higher than alarm value, automatic trigger cylinder sampling will start to analysis of pollutant concentration. The odor activity value (OAV) and weight analysis method were discussed. To establish the pollutants sources, fingerprints and provide reference information for inspection control by Environmental Protection Bureau local government were also major objectives of this research. This research is based on the high-odor pollution of Toufen industrial zone in Miaoli County. The industrial zone has the highly potential for odor pollutants emissions factory, including the H company (plastic products manufacturing), the C company (chemical materials manufacturing), F Company (textile industry), T Company (chemical materials manufacturing), O Company (chemical materials manufacturing), S Company (chemical materials manufacturing), and V Company (chemical materials manufacturing). The results of the study showed that 5 automatic samplings were triggered and 62 pollutants were analyzed during the monitoring period. The main pollutants were toluene (9.88 ppb), meta-xylene (2.64 ppb), cis-1,2-dichloroethylene (2.56 ppb), ethane (2.26 ppb) and vinyl chloride (1.92 ppb). These pollutants represented and matched the pollution fingerprints of this Toufen industrial zone. According to the analysis results of odor activity value, it obviously showed that toluene (OAV = 0.706), m-xylene (OAV = 0.033), n-propylbenzene (OAV = 0.023), cumene (OAV = 0.018) and isobutyraldehyde (OAV = 0.014) have a highly potential for odor emission. And these pollutants could be regarded as the odor pollution fingerprints of the Toufen industrial zone. Based on the results of weight analysis comparison, the pollutants, such as vinyl chloride, toluene, benzene, methylene chloride and acrylonitrile, should be preferentially controlled in the Toufen industrial zone. The results of the comparison with the raw materials data, H, C, and T company should strengthen the control of toluene and vinyl chloride respectively. However, methylene chloride and acrylonitrile were also still needed to compare and figure out the corresponding pollution emission sources. According to the results of this study, the automatic sampling technology of volatile organic compounds could be used as a model for the controlling of air pollutants by Environmental Protection Bureau of local government, and also could improve the effectiveness of audit control.
