Abstract: In this paper. We have analysed the trace elementr Mo, Cu, Zn of the geographical environments in the Yengtre River delta and adjacent arean in onder to investigate the pathogeny of lives cancer. The primany nerults have been of abtained as below: 1. The disticbution of this Clisease has obvious distvict Characteristis.In the areas of high incedencc, the Content of molybdenum in the water and soil is higher, while in the staple food is lower. Thus it dan be seen that the Content of molybdenum entering human body is lower. The intake of molybdenum scene to have negative relation with the mortality of liver Cancer. 2. The absorption of molybdenum in human body decreases, by excess Cu and SO4, entering local masses through food Chain. It leads to low Content of molybdenum in human body. 3. There phenomena Can checrcase enzywe activity,and form the damage of liver function. On other hand. it aid to synthesize nitrosamine, and to pollute from aflatoxin in the food. These lead to enhance the carcinogenesis of nctro-samine and aflatoxin.
