In this study, seven kinds of synthetic musks were characterized in sediment samples of Yellow River Delta wetland, including celestolide, phantolide, traseolide, galaxolide, tonalide, musk xylene, and musk ketone. They were analyzed using gas chromatography-mass spectrometry (GC-MS), with recoveries of 91.85 %-105.35 % and the relative standard deviation (% RSD) were 3.30 %-8.11 % for all analytes. Galaxolide and tonalide were the main musk contaminants which were detected in sediment samples. The total concentrations of galaxolide ranged from 1.42 to 8.60 ng/g (mean 2.92 ng/g) (dry weight, dw); the total concentrations of tonalide ranged from the detection limit (LOD) to 3.63 ng/g (mean 1.69 ng/g, dw). The one reason of the higher level of SM pollutants was the domestic wastewater dumped by the local residents in some sites. And there was no significant correlation between SMs and TOC in sediment samples of Yellow River Delta wetland (p > 0.05).
在本研究中,对黄河三角洲湿地沉积物样本中的七种合成麝香进行了表征,包括佳乐麝香、芬檀麝香、吐纳麝香、 galaxolide、 吐纳麝香、二甲苯麝香和麝香酮。采用气相色谱 - 质谱联用仪(GC-MS)对其进行分析,所有分析物的回收率为91.85% - 105.35%,相对标准偏差(%RSD)为3.30% - 8.11%。Galaxolide和吐纳麝香是在沉积物样本中检测到的主要麝香污染物。Galaxolide的总浓度范围为1.42至8.60 ng/g(平均值2.92 ng/g)(干重,dw);吐纳麝香的总浓度范围为检测限(LOD)至3.63 ng/g(平均值1.69 ng/g,dw)。合成麝香污染物水平较高的一个原因是当地居民在一些地点排放的生活污水。并且在黄河三角洲湿地沉积物样本中,合成麝香与总有机碳之间没有显著相关性(p > 0.05)。
