Plasma selenium (Se) levels of 293 subjects (160 males and 133 females) living in Desio (a small town near Milan) were determined. Analyses were performed by graphite-furnace atomic absorption spectrophotometry with Zeeman background correction. Plasma samples were not subjected to any treatment before analysis and serum samples containing a certified Se content were used as reference materials to control the quality of the analytical determinations. Plasma Se levels were found to be distributed normally with an average value of 118.8 micrograms/l and a S.D. of 27.2 (95% of the subjects lie between 64.4 and 173.2 micrograms/l). No statistically significant difference was found between males and females, and no correlation was found between plasma Se levels and age or smoking habits.
测定了居住在德西奥（米兰附近的一个小镇）的293名受试者（160名男性和133名女性）的血浆硒（Se）水平。采用带塞曼背景校正的石墨炉原子吸收分光光度法进行分析。血浆样本在分析前未进行任何处理，含有经认证硒含量的血清样本用作参考物质以控制分析测定的质量。发现血浆硒水平呈正态分布，平均值为118.8微克/升，标准差为27.2（95%的受试者硒水平在64.4至173.2微克/升之间）。未发现男性和女性之间存在统计学上的显著差异，且血浆硒水平与年龄或吸烟习惯之间未发现相关性。
