目的：研究电解铝行业生产工人恶性肿瘤的发病及死亡情况。方法：对青铜峡铝厂４２３３名电解铝车间作业工人进行了从１９８７年１月１日至１９９６年１２月３１日为期１０年的全死因、全肿瘤的发病及死亡情况的回顾性流行病学调查。结果：在电解铝车间工人全死因构成中，恶性肿瘤死亡占第１位。在恶性肿瘤的分类构成中，以肺癌居首位，且明显高于１９９０～１９９２年我国居民肺癌死亡率（Ｐ＜００１）。结论：电解铝行业的主要污染物为沥青烟，属多环芳烃，为肯定致癌物，尤其有使作业工人肺癌死亡率增高的趋势。
Objective: To study the incidence and mortality of malignant tumors among workers in electrolytic aluminum industry. Methods: A retrospective epidemiology of the incidence and death of all-cause and all-cause cancer was performed in 4233 workers in the aluminum plant of Qingtongxia Aluminum Plant for a period of 10 years from January 1, 1987 to December 31, 1996 survey. Results: Among all the cause of death of workers in the Electrolytic Aluminum Workshop, the death of malignant tumor ranked No.1. In the classification of malignant tumors, lung cancer ranked first, and was significantly higher than the mortality of lung cancer in our country from 1990 to 1992 (P <001). Conclusion: The main pollutant in the electrolytic aluminum industry is asphalt smoke, which belongs to polycyclic aromatic hydrocarbons. It is a positive carcinogen, especially for workers who have higher lung cancer mortality.
