在德国污水处理厂的废水和污泥中测量了两种多环麝香香料 HHCB（佳乐麝香）和 AHTN（托那内酯）。在同一植物中对代谢物 HHCB-内酯进行了鉴定和定量。进水浓度约为 1900ng/l HHCB 和 580ng/l AHTN，而污泥中的分析浓度约为 3000ng/g HHCB 和 1500ng/g AHTN。大约 35% 的两种化合物未经改变地通过工厂并排放到河流中。污泥中吸附的 HHCB 略多于排出的 HHCB；而对于 AHTN，污泥中吸附的量大约是排放量的两倍。大约 5-10% 的 HHCB 在植物中被氧化成 HHCB 内酯。不过，STP 中的主要过程是吸附过程。 (C) 2004 Elsevier Ltd. 保留所有权利。
Measurements of two polycyclic musk fragrances HHCB (galaxolide) and AHTN (tonalide) were measured in wastewater and sludge of a German sewage treatment plant. The metabolite HHCB-lactone was identified and quantified in the same plant. The influent concentrations were about 1900ng/l HHCB and 580ng/l AHTN, while in the sludge about 3000ng/g HHCB and 1500ng/g AHTN were analysed. About 35% of both compounds passed through the plant unaltered and were discharged to the river. Slightly more HHCB was sorbed to the sludge than was discharged; while for AHTN about twice as much was sorbed to the sludge than was discharged. About 5-10% of the HHCB was oxidised in the plant to HHCB-lactone. The dominant processes in the STP were sorption processes, though. (C) 2004 Elsevier Ltd. All rights reserved.
