李国宏、孙乃珍(岳阳石油化工总厂职业病防治研究所)报道:作者采用甲醛肟比色法对226名电焊工和154名正常人进行了发锰测定,并对发锰作为职业损害指标的意义进行了探讨。结果表明:男女发锰值比较,女性发锰值高于男性,差异在0.05水平上显著,故在进行发锰正常值测定时,应男女分别测定,锰作业组与非锰作业组发锰值比较时,应男女分别比较;电焊工发锰值的含量与车间空气锰浓度、与电焊工龄的长短、与电焊工的症状体征没有
Li Guowei, Sun Naizhen (Yueyang Petrochemical Plant Institute of Occupational Disease Prevention) reported: The author of formaldehyde oxime colorimetric method for 226 welders and 154 normal people were made of manganese determination, and the significance of hair manganese as a target for occupational damage Exploring. The results showed that the male and female hair values were higher than those in male ones, and the differences were significant at 0.05 level. Therefore, when mensurating the normal values of hair manganese, the male and female were respectively measured, and the values of manganese Comparison should be men and women were compared; welding hair hair manganese content and the workshop air manganese concentration, and welding length of service, and the welder’s symptoms and signs are not
