AB  - A simple and solvent-minimized procedure for the determination of six commonly 
      found synthetic polycyclic musks in aqueous samples using ultrasound-assisted 
      dispersive liquid-liquid microextraction (UA-DLLME) coupled with gas 
      chromatography-mass spectrometry (GC-MS) is described. The parameters affecting 
      the extraction efficiency of analytes from water samples were systematically 
      investigated. The best extraction conditions involved the rapid injection of a 
      mixture of 1.0 mL of isopropyl alcohol (as a dispersant) and 10 muL of carbon 
      tetrachloride (as an extractant) into 10 mL of water containing 0.5 g of sodium 
      chloride in a conical-bottom glass tube. After ultrasonication for 1.0 min and 
      centrifugation at 5,000 rpm (10 min), the sedimented phase 1.0 muL was directly 
      injected into the GC-MS system. The limits of quantitation (LOQs) were less than 
      0.6 ng/L. The precision for these analytes, as indicated by relative standard 
      deviations (RSDs), was less than 11% for both intra- and interday analysis. 
      Accuracy, expressed as the mean extraction recovery, was between 71 and 104%. 
      Their total concentrations were determined in the range from 8.3 to 63.9 ng/L in 
      various environmental samples by using a standard addition method.
