[Health status of persons occupationally exposed to chromium, nickel, manganese and polycyclic aromatic hydrocarbons].
Occupational environment monitoring and biological-medical monitoring of persons professionally exposed to welding fumes have been performed. Chromium, manganese and polycyclic aromatic hydrocarbons in welding fumes represents an important health risk. Pollutant concentrations found in metal welding fumes represented only fractions of those acceptable ones. Polycyclic aromatic hydrocarbons have been reached the concentration found in a busy road crossing in Hradec Králové (compared with these as in Czech Republic no maximum acceptable levels for PAHs having been declared). Family, personal and occupational history have been taken. Health state including total haematological count, biochemical and cytogenetical changes of 19 stainless steel welders were checked-up. The level of mercapturates in urine were examined as well. The data were statistically compared with those of non exposed (control group). No changes witnessing the above mentioned risk factors influence on the haematological, biochemical and cytogenetical findings were ever proved. In conclusion, our results did not confirm an increased professional risk in this group of welders.
