目的了解贵州、福建、湖南和云南产香烟中铅的含量。方法从大理市市售香烟中购取4个产地的香烟,采用TAS-990super石墨炉原子吸收分光光度计配合标准曲线法对4个不同产地香烟中铅含量进行测定,对测定结果进行比较分析。结果各地产香烟中铅含量差别很大:贵州为(2.1447±0.28)μg/g、福建为(3.599±0.17)μg/g、湖南为(5.187±0.23)μg/g,分别与云南的(1.2653±0.26)μg/g比较,均差异有统计学意义(P<0.01)。结论中国部分地区产香烟的铅含量差异都比较大,某些品牌香烟中足可造成被动吸烟者血铅水平增高。 Objective To understand the contents of lead in cigarettes produced in Guizhou, Fujian, Hunan and Yunnan. Methods Four cigarettes of origin were purchased from commercial cigarettes in Dali City. The lead contents in four cigarettes of different origin were determined by TAS-990super graphite furnace atomic absorption spectrophotometer combined with standard curve method. The results were compared. Results The results showed that there were significant differences in the lead content of cigarettes in different regions: Guizhou was (2.1447 ± 0.28) μg / g, Fujian was (3.599 ± 0.17) μg / g and Hunan was (5.187 ± 0.23) μg / g, ± 0.26) μg / g, the difference was statistically significant (P <0.01). Conclusion The lead content of cigarettes produced in some parts of China is quite different. Some brands of cigarettes can cause the blood lead levels of passive smokers to increase.
