    Abstract: 塑膠產品的廣泛應用衍生出大量廢棄物,廢棄物的處理不當使得大量塑膠汙染物被排放到環境中,如今塑膠微粒對海洋的污染已經成為全球關注的議題,因其聚合物不易被分解的性質,長時間下易累積於環境中,再加上塑膠易吸附其他有機與重金屬汙染物,使其對生物體有著潛在的危害,而建立塑膠汙染物的檢測方法將能為我們追朔汙染源頭,利於進行整治與改善。
    現今針對塑膠微粒的標準檢測方法尚未定案,而目前普遍的檢測方法,如FT-IR、Raman等光譜技術常包括費工耗時的樣品純化步驟,因此本研究使用簡單的液液萃取法(Liquid-liquid extraction)和基質輔助雷射脫附游離飛行時間質譜技術(MALDI-TOF-MS),並選擇聚苯乙烯(Polystyrene,PS)塑膠微粒作為代表,探討此兩種快速、簡便的方法是否能優化現今塑膠微粒的檢測。
    ;Currently, microplastic particles have been concerned as a group of emerging contaminants in surface water and marine environment. In this study, we combined two simple and rapid tools—liquid-liquid extraction (LLE) and matrix-assisted laser desorption ionization time-of-flight mass spectrometer (MALDI-TOF MS) in order to improve the time-consuming and laborious defects for microplastics particles detection, and polystyrene (PS) was used as the model microplastic particles.
