The total mortality and the incidence of cancer was studied among a cohort of employees at the six oldest ferrosilicon and ferromanganese plants in Norway. The cohort consisted of 6494 men employed for more than 18 months before 1970 and has been followed up from 1953 to 1982. The standardised incidence ratio (SIR) for cancer (all sites) was 0.94. The observed number of cancers was as expected for lung cancer (SIR = 0.99) and for most of the other cancer sites studied. A statistically significant reduction of stomach cancer was found (SIR = 0.72). There was an increased incidence of lung cancer (SIR = 1.75) and cancer of the prostate (SIR = 1.56) in the workers at one ferrosilicon plant and of colonic cancer (SIR = 1.90) at another ferrosilicon plant.
对挪威六家最老的硅铁和锰铁工厂的一批员工的总死亡率和癌症发病率进行了研究。该队列由1970年前受雇超过18个月的6494名男性组成，从1953年至1982年进行了随访。癌症（所有部位）的标准化发病率（SIR）为0.94。观察到的癌症病例数与肺癌（SIR = 0.99）及所研究的大多数其他癌症部位的预期病例数相同。发现胃癌有统计学显著降低（SIR = 0.72）。一家硅铁工厂的工人肺癌发病率增加（SIR = 1.75），前列腺癌发病率增加（SIR = 1.56），另一家硅铁工厂的结肠癌发病率增加（SIR = 1.90）。
