对鞍钢男工中６１０例肺癌新发病例及９５９例对照进行了访问调查。经吸烟、其他肺疾患、家族肿瘤史、食用水果等非职业因素调整后，岗位工龄等于或超过１５年的下列工人的肺癌危险度显著增高：冶炼工和轧钢工（ＱＲ＝１．５，９５％ＣＩ＝１．１～２．２），耐火砖厂工（ＯＲ＝２．９，９５％ＣＩ＝１．４～５．９），装卸工（ＯＲ＝２．５，９５％ＣＩ＝１．０～６．１），焦炉工（ＯＲ＝３．４，９５％ＣＩ＝１．４～８．５）。各种粉尘和Ｂ［ａ］Ｐ暴露与肺癌危险性呈显著的剂量－反应关系，但与粉尘的特殊成分未见此种关联。长期暴露于污染物的钢铁工人的肺癌的危险度增加４０％。
A total of 610 new cases of lung cancer in Anshan Iron and Steel Company and 959 controls were interviewed. After adjusting for non-occupational factors such as smoking, other lung diseases, family history of cancer and eating fruits, the risk of lung cancer was significantly increased for the following workers who worked for more than 15 years: smelters and rolling workers (QR = 1.5,95 % CI = 1.1 ~ 2.2), refractory brick factory workers (OR = 2.9,95% CI = 1.4 ~ 5.9) .0 ~ 6.1), coke oven workers (OR = 3.4, 95% CI = 1.4 ~ 8.5). Dust and B [a] P exposure showed a significant dose-response relationship with the risk of lung cancer, but not with the specific composition of dust. Steelmakers exposed to pollutants for long periods have a 40% increased risk of lung cancer.
