Title Evaluation of workers exposed to dust containing hard metals and aluminum oxide
Bibliographic information Aug. 1998, Vol.34, No.2, p.177-182. 29 ref.
Abstract Fourteen workers exposed to hard metals and aluminium oxide were evaluated by bronchoscopy and bronchoalveolar lavage or by transbronchial biopsy. Microchemical analysis of transbronchial biopsies showed a high lung burden of exogenous particles, especially metals related to their hard metals exposure. Lung tissue and cellular changes which were associated with exposure to hard metals and aluminium oxide corresponded well with the microanalytic test results.Three workers had diffuse interstitial inflammatory changes at biopsy, two of whom were asymptomatic with normal chest X-ray films and one who had clinically evident disease with severe giant cell inflammation. Two other workers showed focal inflammation. The worker showing clinical disease and one asymptomatic worker with interstitial inflammatory changes had elevated bronchoalveolar lavage fluid-eosinophilia counts.
