对三峡库区内食管癌高低发区土壤中的微量元素含量进行了对比。结果显示，食管癌高发区的微量元素（Ｆｅ、Ｍｎ、Ｃｕ、Ｚｎ）有效态含量均大大低于低发区；揭示了土壤中微量元素缺乏与食管癌发病间的密切关系。
The content of trace elements in the soil of high and low incidence areas of esophageal cancer in the Three Gorges reservoir area was compared. The results showed that the effective levels of trace elements (Fe, Mn, Cu, Zn) in the high-incidence areas of esophageal cancer were all significantly lower than those in the low-incidence areas; the close relationship between the lack of trace elements in the soil and the pathogenesis of esophageal cancer was revealed.
