Mortality in workers at a northwestern United States prebake-type aluminum reduction plant was examined in a historical prospective (cohort) study. Although the standardized mortality ratio (SMR) for all causes of death was low (86), lung cancer (SMR 117), pancreatic cancer (SMR 180), lymphatic and hematopoietic cancers (SMR 184), fatal benign tumors of the brain (SMR 391), and pulmonary emphysema (SMR 204) showed excess deaths. Analysis of mortality by job-exposure category, duration of employment and latency suggests that some of the lymphatic and hematopoietic cancers (especially malignant lymphoma), lung cancers and pulmonary emphysema may be of occupational origin in this worker population.
在美国西北部一家预焙型铝冶炼厂工作的工人死亡率，在一项历史性前瞻性（队列）研究中进行了调查。尽管所有死因的标准化死亡比（SMR）较低（86），但肺癌（SMR 117）、胰腺癌（SMR 180）、淋巴和造血系统癌症（SMR 184）、脑致命良性肿瘤（SMR 391）和肺气肿（SMR 204）的死亡人数却有所增加。按工作暴露类别、就业时长和潜伏期对死亡率进行分析表明，在该工人群体中，部分淋巴和造血系统癌症（尤其是恶性淋巴瘤）、肺癌和肺气肿可能源于职业因素。
