对江西省８５个县、市的土壤有效态钼含量及胃癌患者的头发与血清中钼含量的测定及分析，结果显示：土壤有效钼与胃癌死亡率呈负相关（ｒ＝－０．２８５，Ｐ＜０．０１），胃癌患者发钼含量低于健康对照（Ｐ＜０．０１），血清钼亦低于对照（Ｐ＜０．０５）。提示，缺钼是造成胃癌发病率升高的危险因素之一。
The determination of available molybdenum in the soil of 85 counties and cities in Jiangxi Province and the molybdenum content in the hair and serum of gastric cancer patients showed that there was a negative correlation between the effective molybdenum in the soil and the mortality of gastric cancer (r=-0.285, P<0.01), molybdenum content in patients with gastric cancer was lower than that in healthy controls (P<0.01), serum molybdenum was also lower than in controls (P<0.05). It is suggested that lack of molybdenum is one of the risk factors for the increased incidence of gastric cancer.
