Sažetak
The x-ray fluorescence spectroscopy and the spectrophotometric method were used to determine lead concentrations in the air of an auto repair shop. The calibration of the x-ray spectrometer was performed with known concentrations of water solutions of Pb(N03), on filter paper. Samples were prepared by filtration of measured volumes of air. The lead amounts determined were below the maximum permissible concentrations. The results obtained with the spectrophotometric method are also given showing discrepancies between 10 and 30 per cent if compared with the results of x-ray fluorescence spectroscopy.
