摘要
为探讨电感耦合等离子体质谱法(ICP-MS)检测蜂花粉中微量元素的含量,并了解蜂花粉作为营养品的使用价值,采用ICP-MS测定浙江市场收集到的4种蜂花粉中钙、锰、铜、铁、锌、钼、硒等7种微量元素和铅、镉、铬、汞、砷等5种有害元素。运用SPSS 18.0软件对7种微量元素进行主成分分析,结果表明:钙、锰、铁这3种微量元素含量的差异性比较大,可以作为不同品种花粉之间区别的标志元素。有害元素铅的含量略高于或低于国家标准限量,镉、铬、汞、砷等4种有害元素含量比较低,有待安全限量标准的建立。
To discuss the determination of microelement contents in pollens by using inductively coupledplasma mass spectrometry（ICP-MS）, and understand the nutritional value of pollens, contents of 7 kinds ofmicroelements including Ca, Mn, Cu, Fe, Zn, Mo, Se, and 5 kinds of harmful elements including Pb, Cd, Cr,Hg, As were determined from 4 kinds of bee pollens in the markets of Zhejiang. Principal component analysison contents of the 7 kinds of microelements was conducted using SPSS 18.0 software. The results showed thatthere were great differences among contents of Ca, Mn, Fe in bee pollens, and the 3 kinds of microelementswere suggested to be the mark elements. Content of Pb was a little higher or lower than the limit set in nationalstandard. Contents of Cd, Cr, Hg and As were very low, and their limits needed to be set in national standard.
