The mortality of 461 workers who were employed 10 or more years in a Midwest engine and construction equipment plant was examined, using the method of proportional mortality ratios. Both state and national deaths were used as the standard population. Major exposures in this plant included solvents, cutting oils, and metal fumes and dusts. However, precise exposure data were not available. Among white males, no significant deviations from expected deaths were found. Among black males, significant excess deaths were found for all malignant neoplasms combined, for cancer of the pancreas, and for non-Hodgkin's lymphomas. Proportional cancer mortality ratios produced similar results, although the excess of pancreatic cancer in blacks was only significant among those with 20 or more years of service. Although complete occupational histories were not available, these results may provide hypotheses for future studies of workers in heavy machinery production.
采用比例死亡比方法，对在中西部一家发动机及建筑设备工厂工作10年及以上的461名工人的死亡率进行了调查。以该州和全国的死亡人数作为标准人群。该工厂的主要暴露物包括溶剂、切削油以及金属烟雾和粉尘。然而，没有精确的暴露数据。在白人男性中，未发现与预期死亡人数有显著偏差。在黑人男性中，发现所有恶性肿瘤、胰腺癌和非霍奇金淋巴瘤的死亡人数显著超标。比例癌症死亡比产生了类似的结果，尽管黑人胰腺癌的超标仅在工作20年及以上的人群中显著。虽然没有完整的职业史，但这些结果可为今后对重型机械生产工人的研究提供假设。
