以洪泽湖中6种代表性生物为研究对象，采用超声波法提取样品中硝基苯类化合物，用凝胶色谱净化、浓缩，气相色谱/质谱联用法测定。该法与索氏提取法在同等试验条件下进行加标回收试验，前者回收率高且稳定，简便可行。方法检出限为0．008μg/g～0．030μg/g，平均加标回收率为76．5％～109％，重复测定3次的RSD为1．5％～13．0％。

Six representative biological samples from Hongze Lake were selected as researching objects .Ni-trobenzene compounds in biological samples were extracted by ultrasonic extraction .Gel chromatography was ap-plied to cleanup and concentration and quantification was done by GC /MS.Compared with the recoveries of the ultrasonic method and soxhlet extraction method under the same experimental conditions , the former method showed better recoveries and more stable .The detection limits were 0.008 μg/g ~0.030 μg/g.The average spike recovery were from 76 .5%to 109%, and the RSDs of three times repeated measurements were from 1 .5%to 13 .0%.
