Thiocyanates in Sputum: Relation to Welding Fumes, Tobacco Smoking and Carcinogenicity

NABIL I. EBEID

Military Medical Academy Cairo, Egypt

Thiocyanate in sputum has been examined among 60 individuals. Thirty-two were exposed to welding fumes, 28 were not. The smoking history of the cases has been examined.Thiocyanate level was higher among smokers both among those exposed to welding fumes and control cases. Workers exposed to welding fumes did not have higher thiocyanate levels in sputum.Thiocyanate is a catalyst of N-nitrosamine compounds which is a supposed carcinogen in man.The relevance of carcinogenicity to exposure to welding fumes cannot be concluded from this study. Although there is some evidence of this relationship in international literature, this might be among subgroups of welders.
