卤鸭肝中有害金属元素污染水平的风险评估

Study on the Risk of Pollution Level of Harmful Metallic Elements in Spiced Duck Liver

采用等离子发射光谱仪(ICP-AES)法对卤鸭肝制品进行重金属元素分析测试,并进行风险评估。所采用方法的加标回收率为96.2%～103.5%,RSD为0.3601%～2.214%,检出限为0.0018～0.0342μg/mL。实验表明:零售摊位上的卤鸭肝制品中的铜和铅的含量较高,Cu含量在20mg/kg以上,Pb含量在0.6mg/kg以上,可能存在铜和铅元素的污染风险。

Heavy metals in Spiced Duck Liver was analyzed by Inductively Coupled Plasma Atomic Emission Spectrometry （ICP- AES）,and the risk was evaluated. The recovery was between 96.2% and 103.5%, RSD was 0. 360 1% - 2. 214% and the detection limit was 0. 001 8 - 0. 034 2μg/mL. The method was accurate and precise. The result indicated that the Spiced Duck Liver from retail stall had higher content of Cu and Pb, and the concentrations of cuprum and plumbum element were over 20 mg/kg and 0.6 mg/kg, respectively. It may have the pollution risk of excessive intake of cuprum and plumbum element. Excessive consumption of Spiced Duck Liver may affect people＇s health,and children should not eat too much.
