Concentrations of 28 novel and legacy perfluoroalkyl and polyfluoroalkyl substances (PFASs) in wastewater from 77 industrial plants in the largest industrial complex in Korea were determined. The industrial plants were of eight types (advanced electronic, battery, chemical, general electronic, glass and ceramic, metal, polymer, and textile). PFAS concentrations in river water receiving the wastewater were determined to assess the impact of wastewater from the industrial complex. Only 19 and nine target PFASs were detected in untreated industrial wastewater and river water, respectively. Novel PFASs such as F53B (6:2 chlorinated polyfluoroalkyl ether sulfonate) were not detected. The mean PFASs concentration in industrial wastewater treatment plant effluent was 5.18 µg/L. The mean total PFASs concentration was highest in advanced electronic plant effluent, second highest in general electronic plant effluent, and lowest in battery and chemical plant effluents. Perfluorohexane sulfonate was the dominant homolog, being detected in effluent from plants of all classes and contributing 96% of total discharged PFASs by mass. Perfluorooctane sulfonate (included in the Stockholm Convention) use has decreased markedly since previous studies. Perfluorooctane sulfonate has largely been replaced by PFASs with fewer than seven carbon atoms. A similar change was found for river water receiving industrial wastewater.
测定了韩国最大工业综合体 77 家工业工厂废水中 28 种新型和传统全氟烷基和多氟烷基物质 (PFAS) 的浓度。这些工业工厂分为八种类型（先进电子、电池、化工、一般电子、玻璃和陶瓷、金属、聚合物和纺织）。测定了接收废水的河水 PFAS 浓度，以评估该工业综合体废水的影响。在未经处理的工业废水中仅检测到 19 种和 9 种目标 PFAS，而在河水中则分别检测到 19 种和 9 种目标 PFAS。新型 PFAS 如 F53B（6:2 氯代多氟烷基醚磺酸盐）未被检出。工业废水处理厂废水中的平均 PFASs 浓度为 5.18µg/L。在先进电子工厂废水中的平均总 PFASs 浓度最高，其次是一般电子工厂废水中的浓度，而电池和化工厂废水中的浓度最低。全氟己烷磺酸盐是主要的同系物，在所有类型工厂的废水中均有检出，其质量占总排放量 PFASs 的 96%。自之前的研究以来，全氟辛烷磺酸盐（已列入《斯德哥尔摩公约》）的使用已显著减少。全氟辛烷磺酸盐已被碳原子数少于七个的 PFASs 大量取代。在接收工业废水的河水中也发现了类似的变化。
