RT Journal Article SR Electronic T1 Exposure to stainless steel welding fumes and lung cancer: a meta-analysis. JF Occupational and Environmental Medicine JO Occup Environ Med FD BMJ Publishing Group Ltd SP 335 OP 336 DO 10.1136/oem.51.5.335 VO 51 IS 5 A1 Sjögren, B A1 Hansen, K S A1 Kjuus, H A1 Persson, P G YR 1994 UL http://oem.bmj.com/content/51/5/335.abstract AB 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.
