电感耦合等离子体原子发射光谱(ICP-AES)法测定胡蜂酒中无机元素

采用电感耦合等离子体原子发射光谱法测定胡蜂酒中20种无机元素,建立无机元素对照指纹图谱,对重金属元素进行风险评估。结果表明,胡蜂酒中无机元素种类丰富,其中P、K、Na元素占测定总元素的96.14%。有害元素Pb、Cd、As、Hg、Cu含量符合国家药典标准要求,Cu的靶标危险系数(THQ)为1.00×10^-2,THQ<1说明摄入的重金属对人体健康造成的影响不明显。不同产区胡蜂酒金属元素含量存在差异,根据金属元素图谱得出元素含量按原子序数顺序出现相似的分布态势。结果表明,胡蜂酒中含有丰富的金属元素,很多为营养微量元素,有害元素(Pb、Cd、As、Hg、Cu)含量符合药典要求,从金属元素方面单一来看,饮用胡蜂酒没有明显的健康风险。胡蜂酒无机元素指纹图谱可为胡蜂酒的鉴别提供一定的的参考依据。

Determination of Inorganic Elements in Vespa Wine by Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES)

Inductively coupled plasma emission spectrometry (ICP-AES) was used to determine 20 kinds of inorganic elements in wasps wine. The results showed that there were many kinds of metal elements in wasps wine, of which P, K and Na accounted for 96.14% of the total elements. The contents of harmful elements Pb, Cd, As, Hg and Cu meet the requirements of national pharmacopoeia standards, and the target risk coefficient (THQ) of Cu is 1.00×10^-2. THQ < 1 indicates that the intake of heavy metals has no obvious impact on human health. The contents of metal elements in wasps wine from different producing areas were different. According to the atlas of inorganic elements, the contents of inorganic elements showed a similar distribution trend according to the order of atomic number. In conclusion, there are many kinds of metal elements in wasps wine, and there are many nutritional trace elements. The content of harmful metal elements meets the requirements of pharmacopoeia. From the single point of view of metal elements, there is no obvious health risk for drinking wasps wine. The fingerprint of inorganic elements in wasps wine can provide some reference for the identification of Wasps.
