Effects of the extraction temperature, pressure, and cosolvent volume on the extraction efficiency were investigated by extracting spiked oyster samples. The results show that the maximum extraction efficiency was obtained at 40\u00b0C, 12\u00a0MPa, and a cosolvent (dichloromethane) volume of 5.0\u00a0mL. Under these conditions, the calibration curves had good linearity with square of the correlation larger than 0.998 in the concentration range of 5\u2013800\u00a0ng\/mL; limit of detection and limit of quantitation were 0.16\u20132.83 and 0.55\u20139.43\u00a0ng\/g, respectively. At spiked levels of 10, 30, and 50\u00a0ng\/g, the average recoveries were 70.4\u201380.4% for polycyclic aromatic hydrocarbons, 74.0\u201383.6% for polychlorinated biphenyls, and 66.9\u201378.0% for polybrominated biphenyl ethers, with average relative standard deviations of less than 16.3%. The established method has no significant differences in recovery compared to traditional methods and is suitable for the analysis of real samples.<\/jats:p>","DOI":"10.1002\/jssc.201700043","type":"journal-article","created":{"date-parts":[[2017,7,26]],"date-time":"2017-07-26T02:52:45Z","timestamp":1501037565000},"page":"4213-4221","source":"Crossref","is-referenced-by-count":2,"title":["Development
