【摘要】 目的测定沙棘中4种重金属元素含量,并对其健康风险进行初步评价。方法采用微波消解-电感耦合等离子体发射光谱测定Cu、Pb、Cd 3种重金属元素的含量。结果沙棘果实中Cu、Pb、Cd的含量分别为0.01～0.03、0.423～0.547、0.003～0.004 mg/kg,Cu、Pb、Cd每日摄入量占每日容许摄入量(ADI)的比例分别为0.005×10-3～0.01×10-3%、0.030%～0.038%、0.75×10-4%～0.1×10-3%,对人体的健康风险影响不大。结论从健康风险指数来看,沙棘果实中3种重金属对人体健康不存在风险。更多还原

【Abstract】 [Objective]To determine the content of heavy metals in Seabuckthorn Hippophae,carry out the preliminary assessment on its health risk.[Methods]The contents of Cu,Pb and Cd were determined by microwave digestion-inductance coupling plasma emission spectrometry.[Results]The content of Cu,Pb and Cd in Seabuckthorn Hippophae fruit was 0.01-0.03 mg/kg,0.423-0.547 mg/kg,0.003-0.004 mg/kg,respectively.The ratio of daily intake-to-acceptable daily intake(ADI) of Cu,Pb and Cd was 0.005×10-3%-0.01×10-3%,0.030%-0.038%,0.75×10-4%-0.1×10-3%,respectively,which had less risk on human health.[Conclusion]From the health risk index,Cu,Pb and Cd in Seabuckthorn Hippophae fruit have no risk on human health.更多还原
