Abstract Asbestosis and silicosis are the most common types of pneumoconiosis in Quebec and are often associated with a gradual deterioration in pulmonary function. In this report, the possible role of induced expectoration (IE), a non-invasive technique for analyzing bronchial inflammation, was studied as a means of evaluating the severity of pneumoconiosis and the decline in pulmonary function. The study involved 15 patients diagnosed with asbestosis, 17 with silicosis and 15 controls. Their lung function test data for the previous ten years were analysed, and they were subjected to an additional lung function test and an IE analysis. Findings are discussed. It is concluded that IE could be a useful method to evaluate workers and to follow subjects at risk.
