摘　　要：采用ASE法提取沉积物中16种多环芳烃,以固相萃取法净化提取液,用气相色谱-串联质谱法测定。通过优化测定条件,使方法在5.00μg/L^1 600μg/L范围内线性良好,方法检出限为0.15μg/kg^0.66μg/kg。空白石英砂的加标回收率为61.9%~121%,7次测定结果的RSD为2.6%~11.1%。A method for determination of 16 polycyclic aromatic hydrocarbons（ PAHs） in sediments was developed by using accelerated solvent extraction（ ASE） and solid phase extraction coupled with gas chromatography-triple quadruples mass spectrometry. The results demonstrated that the method had good linearity in the range of 5. 00 μg/L ~ 1 600 μg/L,the detection limits of PAHs were in 0. 15 μg/kg ~ 0. 66 μg/kg. The recoveries were in 61. 9% ~ 121%,the relative standard deviation（ RSD） ranged from 2. 6% to 11. 1% by 7 duplicated measurements.
