我省资料显示，肺癌死亡率80年代比70年代上升了105．5％，其发生、发展比较肯定与大气污染及吸烟习惯等有关，但与化学元素关系的研究报道甚少。作者为观察我省肺癌分布与地球化学元素相关危险因素情况，将资料分析如下。一、资料与方法1．资料：肺癌死亡率资料取自福建省肿瘤 According to data from our province, the mortality rate of lung cancer in the 1980s was 105.5% higher than that in the 1970s. Its occurrence and development are certainly related to atmospheric pollution and smoking habits, but there are few reports on the relationship with chemical elements. In order to observe the risk factors associated with the distribution of lung cancer and geochemical elements in our province, the authors analyzed the data as follows. I. Information and Methods 1. Data: Lung cancer mortality data from Fujian Tumor
