戴奧辛之分析研究於70年代左右，於80年代左右世界各國對戴奧辛於環境中之分佈、特性、含量估算、質量平衡、甚至排放污染源皆做全面性的調查，國內也於90年代開始發展這方面的研究，近幾年來政府也陸續投入相當的資源來做台灣地區戴奧辛調查，主題大都不離廢棄物焚化爐、煉鋼廠、火葬場、水泥窯及一些工業，本研究則針對蜂炮慶典及火災意外這兩種戴奧辛來源，主要內容如下所述。
蜂炮慶典時戴奧辛排放特性之研究，分析15個空氣樣品，所得結果為162 ~ 189(慶典前)、72.9 ~ 90.7(慶典時)、141 ~ 249(慶典後)及22.5(模擬蜂炮實驗前)及285 fg-TEQ/Nm3(模擬蜂炮實驗時)，蜂炮排放係數為0.482 pg-TEQ/枝蜂炮，蜂炮慶典戴奧辛排放量2.41 μg-TEQ，模擬實驗的戴奧辛濃度百分比分佈為蜂炮燃放之戴奧辛分佈特性，主成分及階層群集分析結果將模擬實驗的2個蜂炮樣品歸為同一群，而其他樣品則屬於另一群。
火災意外時戴奧辛排放特性之研究，分析11個擦拭樣品及2個灰渣樣品，所得結果為擦拭樣品1.06 ~ 605 ng/m2及灰渣樣品201 ~ 719 ng/kg，推估全台建築火災戴奧辛大氣排放量為8.92 g-TEQ，約佔全國戴奧辛排放量3.94 %，主成分及階層群集分析結果3個樣品與文獻PVC火災樣品為同一群，其他樣品則與文獻一般火災樣品同群。

The UNEP report of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) inventories points out that the available number of national PCDD/Fs emission inventory is limited. The major sectors of PCDD/Fs release into the air were identified. Nevertheless, there are still un-identified PCDD/Fs sources . As part of our effort to estimate the Taiwan dioxin and furan inventory, we measured the PCDD/Fs concentrations in the ambient air during the FonPau festival in order to investigate whether the proliferation of firecrackers might produce a measurable increase in PCDD/Fs emissions.
The formation of thermally produced PCDD/Fs has been extensively studied. The reduction and elimination of PCDD/Fs can be achieved by optimizing the incinerating parameters and using air pollution control devices . However, certain thermal process such as fire accident, which is not controllable and releases unknown amount of PCDD/Fs. The study of PCDD/Fs in fire accidents is prevalent among researches, for example PVC-fire, house fire, vehicle fire, open-door incineration and municipal waste landfill fire. In November 2001, a fire accident occurred in a private residence and spread to the neighboring pesticide factory in Hsinchu city, Taiwan. A building next to the pesticide factory was heavily smoked during the fire. In this study, we collected and analyzed PCDD/Fs levels in wipe and ash samples from the scene of the fire. Principal component analysis (PCA) was used to compare the PCDD/Fs distribution and to investigate the characteristic of the fire.
