The fate of polycyclic musks (PCMs) (HHCB, AHTN, ADBI, AHDI, ATII, DPMI), UV filters (3-(4-methylbenzylidene) camphor, 4-MBC; octyl-methoxycinnamate, OMC; octocrylene, OC; octyl-triazone, OT) and biocides (permethrin, carbendazim) during wastewater treatment was studied on a full-scale plant. Average influent concentrations of OMC, HHCB, OC, AHTN, 4-MBC and OT were at 20070, 4420, 1680, 1430, 960 and 720 ng L(-1), respectively. The other PCMs, permethrin and carbendazim ranged between < limits of quantification and 670 ng L(-1). Concentrations in the water line decreased significantly for most compounds. Removal rates for PCMs ranged from 72% to 86%, for UV filters from 92% to >99% and were at 92% and 37% for permethrin and carbendazim, respectively. Removal during wastewater treatment was mainly driven by sorption onto solids and biodegradation. For anaerobic sludge digestion, elimination of PCMs, OMC and the biocides was observed.
在一座全尺寸工厂中研究了多环麝香（PCMs）（戊基环己基苯（HHCB）、7-乙酰基-1,1,3,4,4,6-六甲基四氢化萘（AHTN）、1,4-亚丁基二（2,6-二甲基苯并咪唑）（ADBI）、1,4-亚己基二（2,6-二甲基苯并咪唑）（AHDI）、1,3,4,6,7,8-六氢-4,6,6,7,8,8-六甲基环戊并[g]苯并吡喃（ATII）、二苯甲酰甲烷（DPMI））、紫外线过滤剂（3-(4-甲基亚苄基)樟脑、4-甲基苄亚基樟脑（4-MBC）；甲氧基肉桂酸辛酯（OMC）；二乙氨羟苯甲酰基苯甲酸己酯（OC）；乙基己基三嗪酮（OT））和杀生物剂（氯菊酯、多菌灵）在废水处理过程中的情况。OMC、HHCB、OC、AHTN、4-MBC和OT的平均进水浓度分别为20070、4420、1680、1430、960和720 ng L⁻¹。其他PCMs、氯菊酯和多菌灵的浓度在低于定量限至670 ng L⁻¹之间。对于大多数化合物，水管中的浓度显著降低。PCMs的去除率在72%至86%之间，紫外线过滤剂的去除率在92%至>99%之间，氯菊酯和多菌灵的去除率分别为92%和37%。废水处理过程中的去除主要是由吸附到固体上和生物降解驱动的。对于厌氧污泥消化，观察到PCMs、OMC和杀生物剂的去除。
