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).
