Using AAS, the measurements of urine concentrations of lead, cadmium, and zinc, were carried out in workers of open-hearth steel and electrosteel plants. None of elements under investigation was an object of direct steelmaking process. Results of assays were compared with those obtained in subjects residing in the neighbourhood of steel works but being not at work in these plants. Average urine concentration of lead in open-hearth steel plant workers was 59.57 µg/dm3, and that determined in electrosteel plant workers was 56.87 µg/dm3. Both values were essentially greater than those determined in subjects residing in the neighbourhood of steel works (38.55 µg/dm3). Average urine concentration of cadmium in open-hearth steel plant workers, electrosteel plant workers, and subjects being not at work in steelmaking plants, was found to amount to 4.73 µg/dm3, 2.91 µg/dm3, and 1.48 µg/dm3, respectively. Average urine concentration of zinc in both groups of professionally exposed workers, was essentially lower than that determined in subjects being not at work (subjects exposed to environmental hazard).

Oznaczano ołów, kadm i cynk u pracowników stalowni martenowskiej, elektrostalowni i grupie ludzi narażonych środowiskowo. W oparciu o oznaczenie stężeń tych metali w moczu podjęto próbę oceny narażenia zawodowego w porównaniu z narażeniem środowiskowym.
