Summary:
Exposure to workplace airborne pollutants was examined in a group of 20 workers dealing mainly with welding, polishing, drilling and assembling
of stainless steel constructions. Airborne particulate matter (APM) collected using both pe rsonal and stationary samplers was analyzed by
instrumental neutron activation analysis (INAA). Quality assurance procedures of both s ampling and analytical stages are described. Of the elements
determined, results are presented for chromium, iron, manganese, molybdenum, nickel and vanadium. The median values of element concentrations
exceeded the maximum admissible limits for workplace pollutants only for chromium, while f or nickel the limit was exceeded in several individual
cases. Sampling of hair, nails, blood, urine and saliva to be used for biological monitoring of the exposed and control groups is also described.
Key words:
occupational exposure, stainless steel construction industry, instrumental neutron activation analysis, quality control of sampling
