采用微波消解技术,建立了一种测定头足类食药两用生物曼氏无针乌贼肉和海螵蛸中Cr,Mn,Cu,Zn,As,Cd,Hg和Pb等八种微量元素含量的ICP-MS法.测定元索校正曲线的相关系数都在0.997 3以上,样品分析结果的相对标准偏差在2.4%～8.7%之间,加标回收率在96.5%～106.3%之间,最低检出限在0.002～0.032μg·L~(-1)之间.研究结果表明:曼氏无针乌贼肉和海螵蛸中含有丰富的元素Cu和Zn,但是苇金属元素Cd和As含最也超过规定标准,因此曼氏无针乌贼进入市场时,需要对Cd和As含量进行严格的检查.研究结果不仅对曼氏无针乌贼质量控制具有指导意义,而且可为曼氏无针乌贼的养殖、资源利用及产品出口提供科学依据.

An inductively coupled plasma mass spectrometry (ICP-MS) for deterrni-nation of the contents of 8 trace elements in mantle muscle and cuttlebone of Sepiella rnaindroni after microwave digestion of the sample has been developed. Satisfactory linearity of working curves for the 8 elements was obtained, giving all their correlation coefficients over 0. 997 3. The precision of measurement ranges from 2. 4% to 8. 7% in terms of relative standard deviation. The recoveries and the limits of detection are in the range of 96. 5%-106. 3% and 0. 002-0. 032 μg·L~(-1), respectively. It was indicated that the proposed method had the ad-vantages of simplicity, speediness and sensitivity. The results showed that the mantle muscle and cuttlebone of Sepiella main-droni contained rich trace elements Zn and Cu, but the contents of Cd and As are higher than the limits of Chinese Pharmacopoe-ia, Green Trade Standard for Importing and Exporting Medicinal Plant and Preparation and U.S. Food and Drug Standard. Fur-thermore, our study provides new scientific foundation for the quality control, culture, general application, resource utilization and exporting of Sepiella maindroni.
