| 摘 要： | 采用微波消解-电感耦合等离子体质谱法,测定河北省石家庄、保定、蔚县3个烤烟主产区不同部位烟叶样品中11种微量元素(Cr,Co,Ni,Se,Mn,Zn,Cu,As,Cd,Pb,Hg)含量.结果表明:烤烟中微量元素含量呈现地域性差异,Mn,Cu,Zn,As和Pb含量差别较大;不同部位烤烟中各微量元素含量呈现规律性分布,Cu在中、上部叶片含量较高,其余微量元素在下部叶含量较高;Mn在测定的元素中含量最高,具有潜在生理毒性的Cu,Cr,Cd,Pb,Ni,Hg,As含量较低,均达到无公害烟叶生产示范区水平.

| Abstract: | 11 kinds of trace elements(Cr,Co,Ni,Se,Mn,Zn,Cu,As,Cd,Pb,Hg)in flue-cured tobacco samples containing 3 grades from 3 main tobacco-growing areas in Hebei province were detemined by ICP-MS combining with microwave digestion.The results indicated that the trace element contents from different areas were different.The differentiation of Mn,Cu,Zn,As and Pb was significant.The contents of trace elements in different parts distributed regularly.The Cu element accumulated more in middle and upper leaves while the o... |
