摘要

全氟烷基化合物是一種具有極佳的特性而被廣泛使用的化學物質，也因而可以透過不同的傳輸途徑進入到環境中。許多研究已陸續報導全氟烷基化合物對健康所造成的危害，進而讓此類新興化合物越來越受到重視。水庫對台灣的飲用水而言是一個重要的角色，因此如何維持水質並避免有害物質進入水庫成為一個重要的議題。本研究於2019年11月至2020年4月間，採集了台灣6座水庫的表層水與底層水並透過液相層析串聯式質譜儀分析樣品中10種全氟烷基化合物的濃度，來探討全氟烷基化合物在台灣水庫中的分佈、潛在來源及風險。本研究選定6座水庫分別為翡翠水庫、石門水庫、鯉魚潭水庫、明德水庫、仁義潭水庫與澄清湖水庫。表層水中全氟烷基化合物總濃度範圍為

Perfluoroalkyl substances (PFASs) is a group of versatile chemicals which known for their excellent properties and toxicity. They could enter and spread into environmental matrices through various pathways. Concern for PFAS is rising due to updated information and studies that show more threatening health risks and complicated behavior of the newly emerging PFASs. Reservoirs in Taiwan have several important roles, therefore the quality of the water must be maintained to prevent harmful contaminants from entering the human body. To investigate the occurrence, potential source, and risk of 10 PFASs, surface and bottom water layers of six reservoirs in Taiwan were sampled from November 2019 to April 2020 and the concentrations were quantified by UPLC/MS-MS. The studied reservoirs included Feicui Reservoir, Shimen Reservoir, Liyutan Reservoir, Mingde Reservoir, Renyitan Reservoir, and Cheng Ching Lake Reservoir. The total concentrations of PFASs in surface layer and bottom layer ranged from 0.05). Principal component analysis (PCA) and positive matrix factorization (PMF) were employed to identify the source contribution. Both PCA and PMF produced two source apportionment factors. It can be concluded that the first source was derived from domestic daily activity-derived and metal plating, while the second source might be associated with food packaging, outdoor equipment and consumer products. Risk quotients (RQs) and Health Risk Index (HRI) were applied to understand the potential threat of PFASs to the environment and human health. The calculated RQ values were very low, less than 0.01, meaning that PFASs presence in reservoir water is not risky to the aquatic biotas. Likewise with the results of HRI calculation that the values were less than 1, indicating that there are no obvious adverse effects to Taiwanese through the consumption of treated drinking water derived from the studied reservoirs.
