摘　　要：目的了解山东省莲藕中重金属污染状况,并对其进行健康风险评估。方法在山东省16个地市采用分层随用机抽样方法,共采集市售莲藕样品1927份。依据GB 5009.268—2016《食品安全国家标准食品中多元素的测定》和GB 5009.17—2014《食品安全国家标准食品中总汞及有机汞的测定》标准,对莲藕中铅、镉、汞、砷的含量进行测定和分析。采用污染指数法评估莲藕中重金属污染状况,采用目标危害系数法、总目标危害系数法定量评估莲藕中重金属对人体的健康风险。结果山东省莲藕中4种重金属均有不同程度检出,铅、镉、汞、砷含量平均值分别为0.0174、0.0046、0.0018、0.0299 mg/kg,本研究所采集的1927份样品中共42份超标样品,整体合格率为97.82%。莲藕中4种重金属的单因子污染指数及综合污染指数均低于0.7。成人及儿童四种重金属的THQ值、TTHQ值均小于1。结论山东省莲藕中重金属污染水平较低,居民经食用莲藕所暴露的重金属引起的健康风险处于可接受水平,建议持续监测莲藕中重金属水平并评估其健康风险。Objective To investigate the status of heavy metal pollution in lotus root samples in Shandong Province and to assess the health risk.Methods A total of 1927 lotus root samples were collected by stratified random sampling method in 16 cities of Shandong Province.According to GB 5009.2682016"Determination of Multi-elements in Food"and GB 5009.172014"Determination of Total Mercury and Organic Mercury in Food",the contents of lead,cadmium,mercury,and arsenic in lotus root were determined and analyzed.The pollution index method was used to assess the pollution status of heavy metals in lotus roots,and the target hazard coefficient method and total target hazard coefficient method were used to quantitatively assess the health risks of heavy metals in lotus root to human health.Results The four heavy metals in lotus root in Shandong Province were detected to varying degrees.The average values of lead,cadmium,mercury,and arsenic were 0.0174,0.0046,0.0018,and 0.0299 mg/kg,respectively.A total of 42 samples exceeding the standard were collected from 1927 samples in this study,with an overall eligibility rate of 97.82%.The pollution index and comprehensive pollution index of the four heavy metals in lotus root were all lower than 0.7.The THQ and TTHQ values of the four heavy metals in adults and children were all less than 1.Conclusion The overall level of heavy metals in lotus roots in Shandong Province is relatively low.The health risks caused by heavy metals exposed by residents consuming lotus root are at an acceptable level,so it is suggested to continuously monitor the level of heavy metals in lotus root and evaluate its health risk.
