At Sysco Environmental Ltd, we conducted biological monitoring at a site in Rotherham to assess Chromium (VI) exposure among operatives exposed to welding fumes. The methodology involved collecting and analysing a total of five urine samples for the presence of Chromium (VI), with a concentration exceeding 10 µmol/mol creatinine indicative of significant exposure.
The analysis revealed no evidence of Chromium (VI) exposure in any of the samples. The conclusions drawn from the biological monitoring indicate that the exposure of operatives to Chromium (VI) is minimal, with no indication of absorption into their bodies. Chromium (VI) and its metabolic by-products were not detected in the submitted samples, suggesting that the exposure levels are likely well below the established exposure limits.
