“…The HHCB concentrations measured in this study were slightly higher than previously reported values in Germany [37], Thailand [24], USA [28], and China [26] (Table S4). The distribution of SMFs in the STP effluents was dependent on the SMF concentrations in the STP influents, removal efficiency, and the chemical properties of each SMF.…”

“…The average removal rate of SMFs in the four STPs using the MLE and A2O processes (Table S2) was 58.5% for HHCB and 56.8% for AHTN. The HHCB and AHTN removal efficiencies were lower than the values reported in previous studies [23,24,37,38]. Table 3 also shows the concentrations of the nine SMFs (n = 153) in five mainstream sites of the Han River (H1-H5) and 17 tributaries (T1-T17), which were measured every month from March to November 2018.…”

“…The SMF concentrations in the receiving water can be affected by the sewage treatment process and their removal efficiencies in STPs. Several studies have reported the occurrence of SMFs in sewage effluents in several STPs [7,[22][23][24][25][26]. The SMF removal efficiencies in STPs varied from 50% to 90% [25,[27][28][29].…”

Levels of synthetic musk fragrances (SMFs) and various personal care products (PCPs) were measured in the Han River and its tributaries in Seoul, Korea. The most abundant SMF in all river and PCP samples was 4,6,6,7,8,8-hexamethyl-1,3,4,7-tetrahydrocyclopenta(g)sochromene (HHCB), followed by 1-(3,5,5,6,8,8-hexamethyl-6,7-dihydronaphthalen-2-yl)ethanone (AHTN), musk ketone (MK), and 1,1,2,3,3-pentamethyl-2,5,6,7-tetrahydroinden-4-one (DPMI). The most abundant SMF in both PCPs and the Han River samples was HHCB, followed by AHTN. Moving from upstream to downstream in the Han River, the median SMF concentration was 6.756, 2.945, 0.304, and 0.141 μg/L in the sewage treatment plant (STP) influents, effluents, tributaries, and mainstream, respectively, implying that effective SMF removal was achieved during the sewage treatment process, followed by dilution in the receiving water. Four STPs using advanced biological treatment processes had removal efficiencies of 58.5%, 56.8%, and 38.1% for HHCB, AHTN, and MK, respectively. The highest SMF concentrations in the tributaries were observed at locations close to the STPs. Our study confirmed that the main source of SMFs in the receiving water were sewage effluents containing untreated SMFs, which largely originate from household PCPs, especially hair care products (e.g., shampoo) and perfumes.

Reiner et al [28] also reported that HHCB was detected in the concentration range of 1.78-12.7 μg/L in the influent from an urban STP located in New York State, while in the sewage influent in rural Kentucky it was present in the range of 0.043-7.032 μg/L.…”

There was a significant correlation between the SMF concentration in the PCPs and the Han River samples. Moving from upstream to downstream in the Han River, the median SMF concentration was 6.756, 2.945, 0.304, and 0.141 μg/L in the sewage treatment plant (STP) influent, effluent, tributaries, and mainstream, respectively, implying that effective SMF removal was achieved during the sewage treatment process, followed by dilution in the receiving water. Four STPs using advanced biological treatment processes had removal efficiencies of 55.8%, 50.6%, 43.3% for HHCB, AHTN, and MK, respectively. The highest SMF concentrations in the tributaries were observed at locations close to the STPs. Our study confirmed that the main source of SMFs in the receiving water were sewage effluent containing untreated SMFs, which are largely originated from household PCPs, especially hair care products (e.g., shampoo) and perfumes.
