The concentrations of 14 perfluoroalkyl substances (PFASs) and 46 pharmaceuticals in raw water and drinking water from five drinking water treatment plants were determined to assess removal of the chemicals during treatment. 10 out of 14 PFASs were detected in the raw and drinking water samples. The mean perfluorohexane sulfonate concentrations in raw and drinking water were the highest with levels of 106 and 69.6 ng L⁻¹, respectively and the other PFAS concentrations were lower. The ∑₁₄PFAS and individual PFAS removal efficiencies for the treatment plants were −36.9% to 70.7% (mean 31.3%) but the granular activated carbon process removed >80% of the total amount of long-chain PFASs that was removed. The removal efficiency increased as the perfluorocarbon chain length increased. The removal efficiencies increased by 14.2% and 11.2% from the shortest to the longest perfluoroalkyl carboxylic acid and perfluoroalkyl sulfonic acid chain lengths, respectively. 20 out of 46 pharmaceuticals were detected in the raw water samples, but most were removed completely during treatment. Only caffeine, carbamazepine, crotamiton, fenbendazole, metformin, and sulfamethoxazole were detected in the drinking water samples. Oxidation processes contributed >90% of the overall treatment plant removal efficiency except for metformin.

确定了来自五个饮用水处理厂的原水和饮用水中14种全氟烷基物质（PFASs）和46种药物的浓度，以评估处理过程中化学物质的去除情况。在原水和饮用水样品中检测到14种PFAS中的10种。原水和饮用水中的全氟己烷磺酸盐平均浓度最高，分别为106和69.6 ng L ^-1，其他PFAS浓度较低。∑ ₁₄处理厂的PFAS和单个PFAS去除效率为-36.9％至70.7％（平均31.3％），但颗粒状活性炭工艺去除的>长链PFAS总量的80％以上。去除效率随着全氟化碳链长的增加而增加。从最短到最长的全氟烷基羧酸和全氟烷基磺酸的链长，去除效率分别提高了14.2％和11.2％。在原水样品中检测到46种药物中的20种，但在处理过程中大部分已完全去除。饮用水样品中仅检测到咖啡因，卡马西平，克罗米通，芬苯达唑，二甲双胍和磺胺甲恶唑。除二甲双胍外，氧化工艺对整个处理厂去除效率的贡献超过90％。
