页岩型炼油厂作业职工恶性肿瘤流行病学调查

Epidemiological survey of Malignant TumorsAmong the Workers in Shale Refinery

调查显示页岩型炼油厂在页岩干馏及其原油加工过程中，工人肺癌的ＳＭＲ明显增高；工人肺癌死亡与暴露程度存在着高度相关，提示两者可能存在剂量－效应关系。关于页岩型炼油厂的肝癌、食管癌、肺癌的ＳＭＲ增高的原因尚不清楚，需要进一步研究。

The survey showed that the SMR of lung cancer among workers exposed to the processes of shale dry distillation or crude oil processing was obviously increased.The death of workers with lung cancer was closely corelated with the exposure degree,which suggested there was a doseeffect relationship between them.The causes of high SMR in cancers of liver esophagus and lung was still onclear.
