摘要： A multi-residue analysis of six diacylhydrazine insecticides in water, sediment, and aquatic products was established by liquid chromatography triple quadrupole tandem mass spectrometry (LC-MS/MS). The water sample was extracted with acetonitrile by low-temperature enrichment liquid-liquid extraction technology. The sediment and aquatic products were prepared using QuEChERS technique. Method validation showed perfect linearity with correlation coefficients (R) more than 0.9992 for all insecticides, and the matrix effects were nearly negligible (-1.42% to -0.27%) for water, sediment and aquatic products. The recoveries were 80.0-99.7% at three spiked levels (0.02 ng.mL(-1), 0.1 ng.mL(-1), 0.5 ng.mL(-1); 2.0, 10, and 50 ng.g(-1)) and the precisions (intra-day and inter-day precision) were lower than 5.28%, with the low LODs (3.8 similar to 9.6 pg.mL(-1); 0.38-0.96 ng.g(-1)) and LOQs (12.7 similar to 32.0 pg.mL(-1); 1.27-3.20 ng.g(-1)) for water, sediment, and aquatic products, indicating the good accuracy and precision of the proposed method. The applicability, efficiency, and sensitivity of this method have been proved in the analysis of six diacylhydrazine insecticides in water, sediment, and crucian carp in Rice-crucian carp - integrated planting system.
