||This study investigated exposure to chromium (Cr) and nickel (Ni) in flux-cored wire (FCW) welding of stainless steel. Seven FCW welders were monitored by measuring Cr and Ni in the workplace atmosphere, blood and urine. The welders were also questioned about exposure to Cr and Ni, the use of personal protective equipment and their smoking habits. The mean workplace air concentrations were 200µ/m3 for total Cr, 11.3µ/m3 for Cr(VI) and 50.4µ/m3 for Ni. For Cr in whole blood, plasma and erythrocytes, the mean levels after work were 1.25, 1.68 and 0.9µ/l respectively. For Ni, most of the measurements in whole blood and plasma were below the detection limits. Mean levels for Cr and Ni in the urine after work were 3.96 and 2.50 µ/g creatinine, respectively. Correlations between the Cr(VI) levels measured in air and the levels of total Cr in the measured biological fluids were found. Monitoring of Cr in the urine may be a versatile method for evaluating the exposure of FCW welders to Cr(VI) in air. The results seem to suggest that external and internal exposure to Cr and Ni in FCW welders welding stainless steel is low in general.
