为了解发锰含量在电焊工体检中的价值,我们对54名电焊工和113名不从事锰作业的正常人,不论男女均收集长短参杂的混合发5克,采用甲醛肟法测定其发锰含量。结果:54名电焊工发锰几何均值为:2.59微克/克。113名正常人作为对照组其几何均值为:1.13微克/克。两者比较有非常显著差别。113名正常人的发锰值正常范围为:6.15～2.1微克/克。54
In order to find out the value of manganese content in the welder physical examination, 54 welders and 113 normal people who are not engaged in manganese work, both men and women were collected 5 grams of mixed hair length and length were measured by formaldehyde oxime method Manganese content. Results: The average electrical conductivity of 54 welders was 2.59 μg / g. The geometric mean of 113 normal people as a control group was 1.13 μg / g. There is a very significant difference between the two. Normal hair value of 113 normal range: 6.15 ~ 2.1 micrograms / gram. 54
