國內現行的採樣標準方法，多用主動式需外加能源及人為控制的抓取採樣方法，短時間內採集離散的少量體積樣品，後續使用標準方法檢驗，得到採樣時段的檢測結果，數據符合品保/品管規範，可以適時找出超出法規管制標準的污染源，達到管制的目的。然而，對於與時俱變、且濃度變異甚鉅的汙染物，則須提高採樣的時間長度和頻率，方有可能釐清汙染者，導致工作量日增、且花費不貲；對於超微量污染物、或是生物累積性及可利用性毒物，也需加長採樣時間，以採集到儀器足以偵測到的數量，也會遇到類似的問題。被動式採樣裝置不需用外加能源及人為控制，適合長時間連續的採樣，在歐美先進國家已被積極開發作為一種生物暴露風險評估模擬之工具。 本研究提供23篇被動式採樣技術論文之中文摘要，研析其內容，確認泡棉圓盤(PUF disk, PolyUrethane Foam) 和半透膜採樣裝置(SPMD, SemiPermeable Membrane Device) 被動式採樣器可應用於周界空氣中常見持久性有機污染物(POPs)的檢測。PUF disk使用PUF作為截存材料，不需要半透膜包覆，SPMD使用180 l，99%純度triolein作截存材料，半透膜為低密度聚乙烯袋。實地模擬實驗結果顯示PUF disk被動式採樣與主動式採樣標準方法關聯性較好，適合採集空氣中多氯戴奧辛及呋喃(PCDD/Fs)及平面型多氯聯苯(Co-PCBs)。應用模擬實驗得到之飽和曲線以定量際採集之樣品，估算得到之PCDD/Fs及Co-PCBs濃度趨勢與主動式採樣得到濃度相近，兩方法的同源物分布結果有良好的關聯性。研究結果顯示利用PUF disk被動式採樣器於目標採樣點可以半定量空氣中PCDD/Fs及Co-PCBs濃度，分析同源物分佈特性關聯性，可以協助追蹤疑似排放污染源。

The Taiwan standard sampling methods usually require external power and controller. The methods usually collected a small amount of discrete samples which were subsequently analyzed using standard methods. If the data meet the requirements of quality control and quality assurance, we can identify law-violating contaminating source in due time. For contaminant concentration varying with time, we need to prolong sampling time and increase sampling frequency to assist identifying the contaminating source at the price of heavier workload and higher expense. Similar problems are encountered when analyzing ultratrace contaminants, bioaccumulating and bioavailable toxic substances. Passive accumulation devices (PADs) are free of external power and human intervention. PADs are suitable for consecutive longtime sampling and have been used in western countries for risk assessment of biological exposure. Therefore this proposal is to develop a technique for long time passive accumulation, including PUF disk and semipermeable membrane device (SPMD). We collected 23 relevant papers first and provided their Chinese and English abstract. The papers demonstrate that the PUF disk (PUF disk, PolyUrethane Foam) and SPMD (SemiPermeable Membrane Device) (SPMD, SemiPermeable Membrane Device) are suitable for monitoring the POPs (Persistent Organic Pollutants) in ambient air. The PUF disk uses PUF as sequestration material and is free of using semipermeable membrane. The SPMD uses 180 l, 99% triolein as sequestration material and LDPE (Low Density PolyEthylene) tube as semipermeable membrane. The result from on-site calibration experiment demonstrates that the PUF disk producing results in good agreement with those from active sampler and is more suitable for ambient air PCDD/Fs (PolyChlorinated Dibenzo-p-Dioxins/DibenzoFurans) and Co-PCBs (Co-planar PolyChlorinated Biphenyls) sampling. Using the saturating curves from simulating experiment to quantify real samples, the tendency of estimated PCDD/Fs and Co-PCBs concentration are similar to those obtained by standard method of active sampling. Furthermore, the congener concentration distribution is also similar among the two methods. In summary, this research demonstrates that using PUF disk PADs sampling at target area is capable of semi-quantitatively determine ambient air PCDD/Fs and PCBs concentrations. Furthermore, analyzing the congener concentration distribution profiles might assist trace the origin of suspected emission sources.
