Abstract

Aluminium content has been determined by neutron activation analysis in transbronchial biopsy of four workers exposed for 10-37 years to alumina dusts during the electrolytic production of aluminium. These data have been integrated with those from radiological and histological examination. Aluminium levels in the lungs ranged from 400 to 1080 ppm wt.w. There is a good correlation between the aluminium concentrations and the intensity of observed fibrosis as drawn from chest X-ray examinations. The worker with the highest aluminium content (1080 ppm) showed slight but obvious signs of fibrosis while the subject with 400 ppm of aluminium had no clearly detectable fibrosis. The data obtained in our investigation tend to suggest that the recommended standard of 2 mg/m**3 of alumina should be a reasonably safe limit of exposure to alumina in the workplace.
