摘要
Based on the contrastive analysis of element contents from the soil, waters and rice corn in two high-incidence areas of stomach cancer of Changle City and in a low-incidence area of stomach cancer of Fu’an City, the author took the study of the correlation between the stomach cancer and bio-geochemical environment by the mathematical statistics method. It is shown that in the high-incidence area of stomach cancer it is devoid of beneficial elements such as molybdenum in the soil and rice corn, has higher content of toxic elements such as mercury and cadmium in the rice corn and higher harmful elements such as chlorine and manganese in the drinking water of the surveyed area.
