用火焰原子吸收分光光度计对无尘肺隧道工（０期）、０＋接尘工人及Ⅰ期矽肺患者共１３８例进行了人发中微量元素Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ含量的测定分析。结果表明，０期、０＋接尘工人及Ⅰ期矽肺患者与对照组比较，其微量元素含量均有不同程度的下降，０＋、Ⅰ期矽肺患者下降更为明显，有非常显著性差异（Ｐ＜０．０１），Ⅰ期矽肺患者Ｆｅ／Ｃｕ比值明显降低。提示适当补充Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ微量元素，对治疗及预防矽肺可能有益。
The content of trace elements Cu, Zn, Fe and Mn in human hair was determined by flame atomic absorption spectrophotometer in 138 cases of dust-free lung tunnel workers (0 stage), 0 + dust-exposed workers and stage I silicosis patients. The results showed that compared with the control group, the levels of trace elements in stage 0, stage 0 + dust-exposed workers and stage I silicosis patients all decreased to different extents. The decrease in stage 0 + and stage I silicosis patients was more obvious with significant difference (P < 0.01). The ratio of Fe / Cu in patients with stage I silicosis was significantly lower. Tip Cu appropriate supplementation of Cu, Zn, Fe, Mn trace elements, for the treatment and prevention of silicosis may be beneficial.
