1954—1983年云锡矿共发生职工肺癌1,448例,死亡1,253例。1972—1981年井下矿工肺癌发病率为435.44/10~5·年,死亡率为370·16/10~5·年。进一步将工人按主要职业史划分为7组,分别计算其发病率和死亡率。结果发现:有井下作业史的冶炼工人>单纯井下作业工人>单纯冶炼工人>无井下并无冶炼史工人。提示井下及冶炼厂,由于存在某些有害因素导致肺癌增多。通过吸烟与肺癌关系分析表明,吸烟也是一个不可忽视的重要因素。
In 1954-1983, 1,448 lung cancer cases were found in Yun Tin Mine, with 1,253 deaths. The incidence of lung cancer in underground miners from 1972 to 1981 was 435.44 / 10 ~ 5 years with a mortality rate of 370.16 / 10-5 years. The workers were further divided into seven groups by major occupational history, and their morbidity and mortality rates were calculated separately. The results showed that: Smelting workers with downhole work history> simple downhole workers> simple smelters> No underground workers without smelting history. Tips downhole and smelter, because of the existence of some harmful factors leading to increased lung cancer. Analysis of the relationship between smoking and lung cancer shows that smoking is also an important factor that can not be ignored.
