Through scanning electron microscopy an obvious FeK α X ray peak was seen and the surface image of iron element presented a gathering pattern basically similar to that of sedimentary dust , which indicated that iron from sedimentary dust was associated with that from lung tissue .
扫描电镜见到FeKαX射线波峰明显，面分析图像见到铁元素的特征呈聚集状，与降尘的面分析图像基本一致，说明降尘中的铁与肺组织中的铁密切相关。
