中文摘要：
建立了土壤、底泥及植物样品中佳乐麝香和吐纳麝香的分析方法。采用30 mL混合溶剂（正己烷：丙酮,V：V=1∶1）于120℃微波萃取装置上萃取20 min,萃取液浓缩后经硅胶及活性炭/硅胶复合柱净化,二氯甲烷洗脱,洗脱液浓缩定容后用GC-MS-SIM进行检测。实验结果表明,佳乐麝香和吐纳麝香的线性范围为10～1000μg/L,在该范围内相关系数分别为0.9995、0.9964。土壤和底泥中2种多环麝香的检出限为0.66～0.72μg/kg（S/N=3）,植物中的检出限为3.64～3.78μg/kg（S/N=3）。基质加标回收实验的平均回收率为79.4%～90.5%,相对标准偏差为8.5%～13%。
英文摘要：
An efficient microwave-assisted solvent extraction（MASE） method has been developed for the determination of two polycyclic musks in soil,sediment and plants.A centrifuged sample（1 or 5 g）,mixed with 5 g of anhydrous sodium sulfate in a Teflon cell,was extracted with 30 mL of a 1∶1（V/V） mixture of acetone and hexane for 25 min,including a 5 min ramp with a 20 min hold at a controlled temperature of 120°C.After cooling,the extract was evaporated and cleaned up on a silica gel or activated carbon/silica gel column.Then final eluent（dichloromethane） was concentrated before injection.Identification was carried out by GC-MS in the selective ion monitoring（SIM） mode.Using this method,HHCB（Galaxolide） and AHTN（Tonalide） were obtained good linear calibrations in the range of 10～1000 μg/L,and the correlation coefficients were 0.9995 and 0.9964,respectively.The detection limits of polycyclic musks were from 3.64 to 3.78 μg/kg in plants and 0.66～0.72 μg/kg in soil and sediment（S/N=3）.The average recoveries were in the range of 79.4%～90.5% when the spiked concentration was 20 μg/kg.The RSDs ranged from 8.5% to 13%.
