摘　　要：为评价噻唑膦和阿维菌素在山药上使用的安全性,采用超高效液相色谱-质谱联用仪检测,分析山药中噻唑膦和阿维菌素残留量,并运用膳食摄入风险评估模型进行长期膳食摄入风险评估。结果表明,在0.01~1 mg/kg添加水平下,噻唑膦和阿维菌素在山药上的平均回收率分别为87%~110%和80%~89%,相对标准偏差分别为0.6%~5.5%和1.0%~2.6%,山药中噻唑膦和阿维菌素最终残留量均小于0.01 mg/kg。噻唑膦施药有效剂量为3000 g/hm^(2);阿维菌素施药有效剂量为375 g/hm^(2),于播种前施药1次并在收获期采收山药,噻唑膦和阿维菌素的普通人群国家估计每日摄入量分别是0.047、0.059 mg,风险商分别为18.7%、93.4%,说明其对一般消费人群是安全的。To investigate the residues of fosthiazate and abamectin in Chinese yam,the samples were extracted with acetonitrile and detected by ultra high performance liquid chromatography-mass spectrometry,and the residues of fosthiazate and abamectin in Chinese yam were analyzed.Meanwhile,the long-term dietary intake risk assessment model was used to assess the dietary intake risk.The experimental results showed that when the spiking levels were from 0.01-1 mg/kg,the average recoveries of fosthiazate and abamectin in Chinese yam were 87%-110%and 80%-89%.The relative standard deviation were 0.6%-5.5%and 1.0%-2.6%.The final residues of fosthiazate and abamectin in Chinese yam were<0.01 mg/kg.Fosthiazate and abamectin were applied once before sowing at the effective dosage of 3000,375 g/hm^(2),respectively,and Chinese yam was collected at harvest period.The national estimated daily intake of fosthiazate and abamectin for the general population was 0.047 mg and 0.059 mg,and the risk quotient were 18.7%and 93.4%,indicating that the dietary risk caused by fosthiazate and abamectin were safe for general consumers.
