This work summarises the results of biological monitoring regarding the occupational exposure of different groups of workers to hard metals. Samples of airborne dust, blood, urine, pubic hair, toenails and bronchoalveolar lavages were analysed for cobalt, tantalum and tungsten. 251 subjects were included in the study of which 23 workers, representing the highest number of cases monitored, were diagnosed as diseased subjects. The findings supported the theory that the possible haptenic properties of cobalt may induce hypersensitivity and immuno-related toxic effects.
