Because of a reported association between residence in counties with nonferrous smelters and increased risk of lung cancer, we studied the relationship between distance of residence from nonferrous smelters and lung cancer. Patients with lung cancer and patients with other cancers not known to be associated with smelter effluent (breast, prostate, and colon) were compared. All patients lived within a 20-kilometer radius around one of 10 nonferrous smelters in five western states during 1970-1977. Data were obtained from cancer registries or death certificates and were examined separately for each area. Addresses at the time of diagnosis or death were plotted on U.S. Geological Survey maps to calculate distance from each smelter. The distribution of lung cancer near the smelters was not significantly different from the distribution of control cancers in any of the areas studied.
由于有报道称居住在有色冶炼厂所在县与肺癌风险增加之间存在关联，我们研究了居住地与有色冶炼厂的距离和肺癌之间的关系。对肺癌患者和其他已知与冶炼厂废水无关的癌症患者（乳腺癌、前列腺癌和结肠癌）进行了比较。1970年至1977年期间，所有患者都居住在西部五个州的10个有色冶炼厂之一周围20公里半径范围内。数据来自癌症登记处或死亡证明，并对每个地区分别进行检查。将诊断或死亡时的地址标在美国地质调查局的地图上，以计算与每个冶炼厂的距离。在所研究的任何地区，冶炼厂附近肺癌的分布与对照癌症的分布均无显著差异。
