摘　　要：目的调查广东省10个城市市售龙眼中农药残留现状并开展膳食暴露评估,为龙眼生产的合理用药及龙眼中农药残留限量的修订提供参考依据。方法随机采购来自广东省10个城市的200份龙眼样品,对其中的50种农药残留进行检测。统计分析农药残留数据,采用风险熵值进行龙眼膳食暴露风险评估。结果 200份龙眼样品中,检出农药20种,其中检出率最高的农药为多菌灵,高达33.00%(66/200)。84.00%(168/200)的样品检出农药残留,27.50%(55/200)的样品检出2种及以上多种农药残留。检出的20种农药的慢性膳食暴露量占每日允许摄入量的比例(%ADI)均低于9.00%,在0.00%~8.56%之间;急性膳食暴露量占急性参考剂量的比例(%ARfD)均低于100.00%,在0.02%~70.00%之间。根据残留风险得分,检出残留的20种农药可划分为高风险(5种)、中风险(7种)、低风险(8种)3类。结论广东省10个城市龙眼中农药残留慢性膳食摄入风险和急性膳食摄入风险均较低,正常食用龙眼不会对居民健康造成不良影响。Objective To inspect the pesticide residues in longan samples from 10 cities of Guangdong Province and evaluate the health risk of dietary exposure. These collected data were expected to be useful in regulating the concentration of the pesticide residues, and also in supporting safe consumption of longan fruit. Methods 200 longan samples were collected randomly and 50 kinds of pesticde residues were analyzed. The dietary exposure risk was assessed by risk entropy which based on the statistics of pesticide residues. Results 20 kinds of pesticide residues were found in 84.00%(168/200) of the samples, and carbendazim with detection ratio of 33.00%(66/200) was found to be in the highest frequencies of detected pesticides. Further results showed that 27.50%(55/200) samples contained two or more pesticides. For 20 kinds of pesticides with detectable residues, acceptable daily intake(%ADI) was in the range of 0.00% to 8.56%, which was less than 9.00%. The acute reference dose(%ARfD) was ranged from 0.02% to 70.00%, which was less than 100.00%. These 20 kinds of pesticides were divided into three groups namely high risk group(5), medium risk group(7), and low risk group(8) by considering the residue risk score. Conclusion Chronic dietary intake risk and acute dietary intake risk of pesticide residues were relatively low in longan from 10 cities of Guangdong Province, and normal consumption of longan would not cause adverse health effects.
