卷烟中锂、铬、镍、铜、砷、硒、钼、镉、铊和铅含量分析

Analysis of Li,Cr,Ni,Cu,As,Se,Mo,Cd,Tl and Pb in Cigarettes and Cigars

  • 摘要: 采用微波消解-电感耦合等离子体质谱法测定了41个牌号烤烟型卷烟和雪茄烟样品烟丝中的锂、铬、镍、铜、砷、硒、钼、镉、铊和铅含量,并按照类型和价位对卷烟中这10种有害元素含量进行了统计分析。结果发现:①卷烟中锂和铜的含量较高,铊的含量很低,铬、镍、镉、铅、砷、硒和钼7种元素的平均含量为0.55~4.42μg/g;②雪茄烟中铬、镍、砷、钼、镉、铊和铅的含量一般高于烤烟型卷烟,而硒元素的含量则相反,但差别较小;烤烟型卷烟中锂和铜的含量与雪茄烟没有显著差异;③高档卷烟中的锂、镍、镉、铊和铬含量较低,而砷、铅的含量较高;不同价位卷烟的铜、硒和钼含量差异不显著。

     

    Abstract: The contents of lithium(Li),chromium(Cr),nickel(Ni),copper(Cu), arsenic(As),selenium(Se),molybdenum(Mo),cadmium(Cd),thallium(Tl) and lead(Pb) in 41cigarette and cigar samples were determined by inductively coupled plasma mass spectrometry and the contents of the 10 harmful elements in cigarette samples were statistically analyzed in terms of their types and prices.The results showed that:1) Tl content in cigarette samples was very lower,Li and Cu contents were higher,while the contents of other 7 elements were moderate,averaged from 0.55 to 4.42 μg/g;2) the contents of Cr,Ni,As,Mo,Cd,Tl and Pb in cigar samples were higher than those in Virginia type cigarette samples in general,while Se content in cigar was slightly lower;and no significant difference of Li or Cu content between these two kinds of samples;3) the contents of Li,Ni,Cd,Tl and Cr in premium cigarettes were lower,while those of As and Pb were higher.There are no significant differences of Cu,Se and Mo contents between cigarettes of different prices.
