摘要
[目的]了解烤烟品种的重金属富集能力。[方法]利用原子分光光度法对攀西地区烤烟品种云烟85和红花大金元进行了重金属镉(Cd)、铬(Cr)的分析。[结果]云烟85重金属Cd含量最高为1.18 mg/kg,红花大金元最高为1.65 mg/kg;云烟85重金属Cr含量最高达5.96 mg/kg,红花大金元最高为4.95 mg/kg。[结论]Cd、Cr 2个重金属元素的含量在品种及地区间存在较大差异。
[ Objective ] The aim was to understand the heavy metal enrichment ability of flue-cured tobacco varieties. [ Method ] The contents of Cd and Cr of flue-cured tobacco varieties Yunyan 85 and Hongda in Panxi area were measured by atomic spectrophotometry analysis method. [ Result] As for heavy metal Cd, the highest level of Yunyan 85 was 1.18 mg/kg, and the highest level of Hongda was 1.65 mg/kg; as for heavy metal Cr, the highest level of Yunyan 85 was 5.96 mg/kg, and the highest level of Hongda was 4.95 mg/kg. [ Conclusion] The contents of Cd and Cr show large difference in flue-cured tobacco varieties and Panxi area.
