Stainless steel welding is associated with exposure to metals including hexavalent chromium and nickel. This study is a meta-analysis of five studies of stainless steel welders and the occurrence of lung cancer. Asbestos exposure and smoking habits have been taken into account. The calculated pooled relative risk estimate was 1.94 with a 95% confidence interval of 1.28-2.93. This result suggests a causal relation between exposure to stainless steel welding and lung cancer.
不锈钢焊接与接触包括六价铬和镍在内的金属有关。本研究是对五项关于不锈钢焊工与肺癌发生情况的研究的荟萃分析。已考虑到石棉暴露和吸烟习惯。计算得出的合并相对风险估计值为1.94，95%置信区间为1.28 - 2.93。这一结果表明不锈钢焊接暴露与肺癌之间存在因果关系。
