本文对吉林、重庆等６个铁合金厂１９８０年１月份工资在册的４８３１名男性铁合金作业工人以同铁合金厂在地理位置上相近的四个钢坯初轧厂同期５２６０名工人做对照进行了为期１０年（１９８０年１月１日～１９８９年１２月３１日）的回顾性队列研究。研究结果表明：铁合金作业工人全死因、全癌、肺心病－慢支－肺感染、冠心病、呼循其它和消化系病显著超出对照。全癌中只有胃癌显著超出对照（ＳＭＲ为１７０，Ｐ＜０．０５），这种超出似同职业接触有关，但同铁合金作业类型（矽锰、矽铬、其它铁合金等）无关，肺癌有低量超出（ＳＭＲ为１２２，Ｐ＞０．０５），但同职业接触无关。
In this paper, the 4831 male ferroalloy workers who were employed in six ferroalloy plants in Jilin and Chongqing in January 1980 were compared with 5260 workers in the same four steel slab rolling mills with similar geographical positions in the same period of ferroalloy plant for a period of 10 years. Retrospective cohort study (January 1, 1980-December 31, 1989). The results of the study showed that all causes of death, cancer, cor pulmonale-chronic branch-pulmonary infection, coronary heart disease, exhalation and other digestive diseases of ferroalloy workers significantly exceeded the control. In gastric cancer, only gastric cancer significantly surpassed the control (SMR was 170, P<0.05). This exceedance was similar to occupational exposure, but it was not related to the type of ferroalloy (manganese, strontium chromium, other ferroalloys, etc.), and lung cancer was low. Volume exceeds (122 for SMR, P>0.05), but has nothing to do with occupational exposure.
