贵州、福建、湖南与云南产香烟中铅含量的比较

Comparison of Lead Content in Cigarettes from Guizhou,Fujian,Hunan and Yunnan

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 lead content of cigarettes from Guizhou, Fujian, Hunan and Yunnan. [ Methods] The marketed cigarettes in Dali City from 4 different areas were collected. TAS-990 super graphite furnace atomic ＇absorption spectropho- tometer and standard curve method were adopted to detect lead content of the cigarettes, the results were comparatively analyzed. [ Results] The cigarettes from different areas varied significantly in lead content： （2. 1447 ± 0.28 ）μg/g of Guizhou origin, （3. 599± 0.17） μg/g of Fujian origin, （5. 187±0.23） p,g/g of Hunan origin, （ 1. 2653±0.26） μg/g of Yunnan origin, the differences were significant （P 〈0.01 ）. [ Conclusion]The cigarettes from some parts of China vary. significantly in lead content. The lead content of certain brands of cigarettes can lead blood lead levels elevated of passive smokers.
