| 英文摘要 | Two procedures were compared for extraction and clean-up of 20 organophosphorus and 19 pyrethroid pesticides in sediment to identify the more effective procedure for groups of pesticides or individual compounds. In Procedure I, methanol/water and n-hexane were used for extraction, and 1:10 (v/v) dichloromethane in n-hexane and acetone were used as eluents for eluting the analyte through the cartridge, with one evaporating steps on a rotary evaporator and two eluting steps on the cartridge. n-hexane/acetone (2:1, v/v) was used for extraction and elution in Procedure II with one evaporating step on a rotary evaporator and one eluting step on the cartridge. All extractions were performed under an ultrasonic bath and gas chromatography and mass spectrometry were utilized for measurements. Procedure II was developed as a rapid, timesaving, less costly and safer substitute for Procedure I which was an old method. Procedure II was more effective for almost all the organophosphorus pesticides tested and 11 of the 19 pyrethroid pesticides, while Procedure I was more appropriate for analysis of 5 pyrethroid pesticides. However, recoveries of most pyrethroid pesticides were fairly low. Thus, further studies should focus on adjustment and formulation of solvents for more efficient extraction and clean-up of pyrethroid pesticides from sediment samples. |
