Excess cause specific mortality risks among United States foundry workers were studied by examining records maintained by the International Molders and Allied Workers Union. The 2,734 deaths occurring among white or black foundry workers in the United States from 1971 to 1975 were classified by trained nosologists, and cause specific expected deaths for males in the United States were calculated according to age. The contrast between observed and expected number of deaths was summarized as a Proportional Mortality Ratio (PMR), and statistical significance was determined by a chi square test. A significant increase in mortality from malignant neoplasms and nonmalignant respiratory diseases was indicated. Significant deficits occurred for diseases of the circulatory system and deaths resulting from accidents, poisoning, or violence. PMRs for heart disease across all age groups were close to those expected. Mortality patterns for blacks generally paralleled those of whites. Specific etiologic agents responsible for the suggested lung cancer risk were not fully identified. The authors recommend that industrial hygiene surveys be conducted to isolate potential carcinogenic agents and particulate dusts in the foundry environment, and that epidemiologic and medical studies be undertaken to delineate specific job areas associated with increased disease risks.
