The present study investigated the presence of legacy and emerging per- and polyfluoroalkyl substances (PFASs) in river water collected in 2016 up- and downstream from a fluorochemical production plant, as well as in river water from control sites, in The Netherlands. Additionally, drinking water samples were collected from municipalities in the vicinity from the production plant, as well as in other regions in The Netherlands. The PFOA replacement chemical GenX was detected at all downstream river sampling sites with the highest concentration (812 ng/L) at the first sampling location downstream from the production plant, which was 13 times higher than concentrations of sum perfluoroalkylcarboxylic acids and perfluoroalkanesulfonates (∑PFCA+∑PFSA). Using high resolution mass spectrometry, 11 polyfluoroalkyl acids belonging to the C2nH2nF2nO2, C2nH2n+2F2nSO4 or C2n+1H2nF2n+4SO4 homologue series were detected, but only in downstream water samples. These emerging PFASs followed a similar distribution as GenX among the downstream sampling sites, suggesting the production plant as the source. Polyfluoroalkyl sulfonates (C2nH2F4nSO3) were detected in all collected river water samples, and therefore appear to be ubiquitous contaminants in Dutch rivers. GenX was also detected in drinking water collected from 3 out of 4 municipalities in the vicinity of the production plant, with highest concentration at 11 ng/L. Drinking water containing the highest level of GenX also contained two C2nH2nF2nO2 homologues.

荷兰的一家氟化工厂附近的河流和饮用水中存在全氟和多氟烷基物质（PFAS）
本研究调查了2016年从含氟化合物生产厂上下游收集的河水中以及荷兰控制点的河水中存在的遗留和新兴的全氟烷基物质和多氟烷基物质（PFAS）。此外，从生产厂附近以及荷兰其他地区的市政当局收集了饮用水样品。在生产工厂下游的第一个采样点，在所有下游河流采样点检测到全氟辛烷磺酸替代化学品GenX，其最高浓度（812 ng / L）比全氟烷基羧酸和全氟烷磺酸总和（∑PFCA +）的浓度高13倍。 ∑PFSA）。使用高分辨率质谱法，属于C的11个多氟烷基酸检测到2 n H 2 n F 2 n O 2，C 2 n H 2 n +2 F 2 n SO 4或C 2 n +1 H 2 n F 2 n +4 SO 4同源序列，但仅在下游水中样品。这些新兴的PFAS在下游采样点之间的分布与GenX相似，表明生产工厂是来源。多氟烷基磺酸盐（C 2 n H 2 F 4 n在所有收集的河水样品中都检测到了SO 3，因此似乎是荷兰河流中普遍存在的污染物。在生产工厂附近的4个城市中，有3个城市的饮用水中也检测到GenX，其最高浓度为11 ng / L。含有最高水平GenX的饮用水还含有两个C 2 n H 2 n F 2 n O 2同源物。
