Abstract: ObjectiveThe aim of this study was to explore the residue levels of carbendazim,acetamiprid and aba-mectin in Vigna unguiculata L. Walp produced in Hainan and the potential dietary risk from the consumption of V. unguicu-lata,in order to provide reference for risk supervision of V. unguiculata.MethodResidues of carbendazim,acetamiprid and abamectin in 295 V. unguiculata samples collected in Hainan were analyzed by ultra-high performance liquid chroma-tography-tandem mass spectrometry,and then dietary risk of the three pesticide residues was assessed with hazard index (HI).ResultPositive pesticide residues were detected in 242(82.0%)samples out of 295 V. unguiculata samples. Detec-tion rates of carbendazim,acetamiprid and abamectin in the samples were 45.8%,64.4%and 28.8%,with residue value ranging from 0.016-3.049,0.015-1.710 and 0.011-0.312 mg/kg respectively. The highest HI for residues of carbendazim, acetamiprid and abamectin from consumption of V. unguiculata were 0.200,0.262 and 0.718 respectively.ConclusionThe dietary exposure risk of acetamiprid,carbendazim and abamectin in V. unguiculata from Hainan are acceptable and does not pose serious hazard to public health.
