||Epidemiological survey of workers exposed to cobalt oxides, cobalt salts, and cobalt metal
||Sep. 1993, Vol.50, No.9, p.835-842. 35 ref.
||A cross-sectional study was carried out among 82 workers in a cobalt (Co) refinery to assess whether exposure to pure Co dust (metal, oxides or salts) may lead to adverse health effects. The results were compared with those in a sex- and age-matched control group. The exposed workers complained more often of dyspnoea and wheezing and had significantly more skin lesions than control workers. No lung abnormalities were detected on the chest radiographs in both groups. The results suggest that exposure to high airborne concentrations of Co alone is not sufficient to cause pulmonary fibrosis. This finding is compatible with experimental studies indicating that interaction of other airborne pollutants with Co particles play a part in the pathogenesis of parenchymal lung lesions.
