Abstract: Four techniques, Soxhlet extraction （SOX）, ultrasonic extraction （USE）, fluidized-bed extraction （FBE） and acce-lerated solvent extraction （ASE） with different solvents （methanol, hexane/acetone and acetonitrile） were used for theextraction of DDT analogues in sediments. Results revealed that the four extraction techniques had high recoveries （＞86.0%） with low standard deviations （＜ 12.0%） for most of DDT analogues, meaning that they could all successfully extractDDT analogues in sediments. Accelerated solvent extraction using methanol and hexane/acetone （1:1）, fluidized-bedextraction using hexane/acetone （1:1） and the ultrasonic extraction using hexane/acetone （1:1） were comparable or betterthan Soxhlet extraction using hexane/acetone （1:1）. Considering solvent- and time-consumption, level of automation,and environmental risk, accelerated solvent extraction with hexane/acetone （1:1） was better than the other extractiontechniques.
