本研究目的係在利用液態被動式採樣器(LPS)針對合成皮工廠中二甲基甲醯胺(DMF)進行暴露評估研究，以探討現行法規中利用矽膠管和活性碳管採樣的方法，進而更能精準評估勞工暴露濃度。同時並探討DMF環境測定。在進行DMF的暴露濃度測定時，於作業現場中以LPS、主動式採樣器（矽膠管、活性碳管）、衝擊瓶、和臂章式採樣器3M 3500等五種採樣方式，同時進行平行採樣並分析，來探討之間的相關性，以評估用LPS採集DMF的可行性。 其結果顯示臂章式採樣器3M 3500最差，其次為活性碳管。高濕度下LPS、矽膠管、活性碳管和衝擊瓶之相關係數皆在0.75以上。但在低濕度下LPS與矽膠管之相關係數0.81，濃度大致相同，而活性碳管與各採樣器之關係皆不佳。衝擊瓶為較佳採樣方法，但具有不便性；LPS具有輕巧、便利、使用簡單、可重複使用及變異性小等優點，雖然高濕度下因擴散關係會受影響。故LPS對於二甲基甲醯胺不失為一種可行方法的採樣方法。
