摘要

受到人類生活型態改變與分析技術與儀器進步之影響，逐漸發現更多新興污染物存在於環境水體，並將可能透過飲用水源進入動植物或人類體內。本文將說明液相層析串聯質譜儀（LC-MS/MS）分析新興污染物方法概要與處理困難，並於全台淨水場、高雄阿公店水庫、台南白河水庫等飲用水水源進行數項新興污染物定期檢測。結果顯示，農藥與農藥降解產物在淨水廠清水中幾乎零檢出，降解產物則在所有採樣區域中普遍比農藥本身有更高的檢出頻率。在阿公店水庫與白河水庫中，共通檢測項目為雙酚A、農藥與農藥降解產物、氧四環素，結果顯示除了雙酚A，阿公店水庫皆有比白河水庫更高的檢出濃度。另外針對有溫泉產業的白河水庫流域，則有測得微量抗菌劑三氯沙。

The occurrence of emerging contaminants is greatly influenced by human activity. Due to the development of advanced analytical instruments, detection of trace contaminants in water samples becomes more easily with appropriate pretreatments. This article briefly introduces the detection of emerging contaminants in drinking water and surface water samples by LC-MS/MS. The analytical procedures and the difficulties were discussed. Several emerging contaminants were monitored to investigate whether drinking water quality is influenced by human activity or not. The residual concentrations of herbicides and herbicide degradation product were non-detected after water treatment procedures. However, herbicide degradation product had been detected more frequently than its parent compound in all three types investigated samples. In Baihe reservoir, emerging contaminants (herbicides, herbicide degradation product and oxytetracycline) occurs at lower concentrations than those in Agongdian reservoir. The results indicate that Agondian reservoir undertook more contaminants from human activities. Since hot springs exist in Baihe, samples collected from hot spring hotel's wastewater and neighbor river were detected with the occurrence triclosan(ND-0.14 μg/L) and perfluorooctanoic(ND-8.2 ng/L) respectively. The analytical procedures and the difficulties were also discussed.
