Abstract
We measured the prevalence, severity and histologic character of pulmonary lesions due to dust exposure among Hispanic farmworkers in California. Hispanic males in Central California show early, subclinical histopathological changes consistent with silicosis and mixed-dust pneumoconiosis. Changes were associated with greater severity of dust scores in farmworkers than in non-farmworkers. The natural history and clinical significance of these changes remains to be determined.
