应用原子吸收光谱分析法,测定了在南京从事不同作业的360名健康成人血清中Cu、Fe、Zn、Cd、Pb、Mn、Cr、Ca、Mg、K 10种元素的含量,经分组统计处理,探讨了不同工种、性别、年龄及工龄与血清元素水平的关系。结果表明,不同工种间血清Cu、Fe、Zn、Cr、Mn、Pb、Ca、Mg、K含量均有显著性差异;不同年龄段血清Cu、Zn、Cd、Mn、Pb、Mg含量有显著差异;女性血清Cu、Zn、Ca、K含量高于男性,而血清Cd低于男性;不同工龄间血清Cu、Fe、Zn、Cd、Cr、Pb、Mg含量有显著性差异。 The contents of Cu, Fe, Zn, Cd, Pb, Mn, Cr, Ca, Mg and K in serum of 360 healthy adults working in different jobs in Nanjing were measured by atomic absorption spectrometry. , Discussed the different types of work, gender, age and seniority and serum elemental levels. The results showed that the contents of Cu, Fe, Zn, Cr, Mn, Pb, Ca, Mg and K in serum of different types of workers were significantly different. The contents of Cu, Zn, Cd, Mn, Pb and Mg in serum of different ages were significantly different The content of serum Cu, Zn, Ca, K in female was higher than that in male, while serum Cd was lower than that in male. There was significant difference in serum Cu, Fe, Zn, Cd, Cr, Pb and Mg among different working ages.
