[Health status in stainless steel welders]

Health state, as well as hematological, biochemical and cytogenetical changes of 53 stainless steel welders were checked-up. Results were compared to those of non exposed persons (control), and to a group of firemen. Urine metals concentrations correlated with the welding fumes density. In the majority of welders typical complaints appeared: aqueous nasal secretion of a clogged nose feeling. Only some of workers suffered from a metal vapours fever. No changes witnessing the above mentioned risk factors influence on the hematological and biochemical findings were ever proved. Cytogenetical analysis confirmed an increased genetic risk.
