The occurrence of potentially persistent and mobile (PM) organic micropollutants (OMP) in the aquatic environment is recognized as a severe threat to water resources and drinking water suppliers. The current study investigated long-term fate (persistency and bio-transformation) of several emerging contaminants in a simulated bank filtration (BF) for the first time. In parallel, four sand column systems were operated with groundwater and continuously spiked with an average concentration of 1 μg/L for 24 OMP. Each column system consisted of two sand columns connected in series. Presumably, biological activities in the first column were higher than in the second column, as dissolved oxygen utilization, dissolved organic matter (DOM) and UV absorbance at 254 nm (UV₂₅₄) reduction rates were high in the first column. This study revealed that 9 out of 24 OMP were persistent and mobile throughout the study under oxic conditions and within a hydraulic retention time (HRT) of 12 days. However, 2 (out of 9) OMP were persistent but showed sorption behavior. 15 (out of 24) OMP displayed bio-transformation, 4 were eliminated entirely within 4.5 days of HRT. Others showed constant or improved degradation with the adaptation (or operation) time. Improved degradation with adaption was high in the bioactive sand columns. However, 8 OMP showed improved elimination at high HRT, even in low biologically active columns. In addition, no significant effect of the DOM on the eliminations of OMP was found except for 4-hydroxy-1-(2-hydroxyethyl)-2,2,6,6,-tetramethylpiperidine (HHTMP), 2-methyl-2-propene-1-sulfonic acid (MPSA) and sulfamethoxazole (SMX). The eliminations of HHTMP (Pearson's r > 0.80, p < 0.05), MPSA (Pearson's r > 0.70) and SMX (Pearson's r > 0.80) correlated with the removals of humic substances in the sand columns. Overall, adaptation time and HRT play a crucial role in the elimination of emerging OMP through BF, yet at the same time several OMP exhibit persistent behavior.

水生环境中潜在持久性和移动性（PM）有机微污染物（OMP）的出现被认为是对水资源和饮用水供应商的严重威胁。目前的研究首次调查了模拟银行过滤（BF）中几种新兴污染物的长期命运（持久性和生物转化）。同时，使用地下水运行四个砂柱系统，并连续添加平均浓度为 1 μg/L 的 24 OMP。每个柱系统由两个串联的砂柱组成。据推测，第一根柱中的生物活性高于第二根柱中的生物活性，因为第一根柱中溶解氧利用率、溶解有机物 (DOM) 和 254 nm 处的紫外线吸光度 (UV ₂₅₄ ) 降低率较高。这项研究表明，24 个 OMP 中有 9 个在整个研究过程中在有氧条件下和 12 天的水力保留时间 (HRT) 内具有持久性和可移动性。然而，有 2 种（9 种）OMP 具有持久性，但表现出吸附行为。 24 种中的 15 种 OMP 显示出生物转化，其中 4 种在 HRT 的 4.5 天内完全消除。另一些则随着适应（或操作）时间的推移，表现出持续或改善的退化。生物活性沙柱中的适应降解程度较高。然而，即使在低生物活性柱中，8 OMP 在高 HRT 下也显示出更高的消除效果。此外，除了 4-羟基-1-(2-羟乙基)-2,2,6,6,-四甲基哌啶 (HHTMP)、2-甲基-2- 之外，DOM 对 OMP 的消除没有显着影响。 1-丙烯磺酸 (MPSA) 和磺胺甲恶唑 (SMX)。消除了 HHTMP（Pearson r > 0.80，p < 0.05）、MPSA（Pearson r > 0.70）和 SMX（Pearson r > 0）。80）与沙柱中腐殖质的去除相关。总体而言，适应时间和 HRT 在通过 BF 消除新出现的 OMP 方面发挥着至关重要的作用，但同时一些 OMP 表现出持久的行为。
