多环麝香广泛用于化妆品和其他个人护理和家庭清洁产品。研究了西安市两个污水处理厂（STP）三种不同工艺中两种代表性多环麝香--佳乐麝香（HHCB）和托纳麝香（AHTN）的产生和去除情况。样品经固相萃取预浓缩后，用改进的方法进行气相色谱-质谱联用（GC/MS）分析。HHCB在进水中的浓度范围为82.8 ~ 182.5 ng·L-1，在出水中的浓度范围为22.6 ~ 103.9 ng·L-1。进水中的AHTN为11.0 - 19.3 ng·L−1，出水中的AHTN为2.2 - 8.8 ng·L−1。HHCB和AHTN对两种麝香的去除率分别为43.1%~ 70.4%和54.2%~ 84.4%。3种工艺的水相中两种麝香的浓度沿着段略有增加，在生物处理过程中显著去除，表明所选麝香在不同活性污泥工艺中均能得到显著去除。与传统工艺相比，活性污泥高级工艺在选择性麝香去除方面并没有表现出明显的优势。活性污泥对麝香的选择性去除主要是由于活性污泥的吸附作用。HHCB/AHTN比值沿着处理流程没有明显变化，表明每个污水处理结构对两种麝香的去除效率相似。
Polycyclic musks are widely used for cosmetics and other personal care and household cleaning products. The occurrence and removal of two representative polycyclic musks, galaxolide (HHCB) and tonalide (AHTN) were investigated in three different processes of two sewage treatment plants (STPs) in Xi’an, China. The samples were preconcentrated by solid phase extraction procedure and analyzed using a gas chromatography mass spectrometry (GC/MS) by a modified procedure. The HHCB was in the range of 82.8 to 182.5 ng·L−1 in the influents and 22.6 to 103.9 ng·L−1 in the effluents. The AHTN ranged from 11.0 to 19.3 ng·L−1 in the influents and 2.2 to 8.8 ng·L−1 in the effluents. The removal efficiency of the two musks varied in the ranges of 43.1%–70.4% for HHCB and 54.2%–84.4% for AHTN. Concentrations of the two musks in aqueous phase of three processes slightly increased along the primary process, and significantly removed during the biologic treatment processes, revealing that the selected musks could be remarkably removed in varied activated sludge processes. Advanced processes of activated sludge did not show a significant superiority on selected musk removal compared to the conventional process. The selected musk removal mainly resulted from the adsorption function of activated sludge. There was no significant change of HHCB/AHTN ratios along the treatment flow, indicating that each sewage treatment structure had a similar removal efficiency for the two musks.
