海南豇豆多菌灵、啶虫脒和阿维菌素残留及其膳食风险评估

【目的】探明海南产区豇豆中多菌灵、啶虫脒和阿维菌素的残留水平及膳食暴露风险情况,为豇豆风险监管提供科学依据。【方法】应用超高效液相色谱—串联质谱法对采自海南省的295份豇豆样品中多菌灵、啶虫脒和阿维菌素残留进行检测,通过风险商(HI)对3种农药残留膳食风险进行评估。【结果】295份豇豆样品中有242份(82.0%)样品农药残留为阳性,多菌灵、啶虫脒和阿维菌素在样品中的检出率分别为45.8%、64.4%和28.8%,残留值范围分别为0.016~3.049、0.015~1.710和0.011~0.312 mg/kg。通过食用豇豆摄入多菌灵、啶虫脒和阿维菌素残留的最高HI分别为0.200、0.262和0.718。【结论】海南产区豇豆中多菌灵、啶虫脒和阿维菌素的膳食暴露风险在可接受水平,不会给公众健康带来危害。

Residue analysis and dietary risk assessment of carbendazim,acetamiprid and abamectin in Vigna unguiculata L. Walp in Hainan

Objective]The 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.Method]Residues 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).Result]Positive 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.Conclusion]The dietary exposure risk of acetamiprid,carbendazim and abamectin in V. unguiculata from Hainan are acceptable and does not pose serious hazard to public health.
