The nonspecific respiratory symptoms of asbestos (1332214) workers were assessed. The relationship between concentrations of airborne dust, length of exposure, total exposure, pulmonary impairment, and smoking were studied in two asbestos mines, two asbestos cement factories, and an asbestos textile factory (1242 workers). Asbestos workers were 16 to 59 years old with an exposure duration of 1 to 27 years. Respiratory symptoms were found more frequently than lung function or radiographic changes with a strong relationship to duration of exposure and total particle years. Chronic cough and dyspnea were the most frequent respiratory symptoms. All symptoms were less related to asbestos fiber years than to particle years. Asbestos workers had lung function values lower than expected for a corresponding population with no dust exposures. The index of lung function deficit was 0.2 for duration of exposure. Between fiber years or total particle years, the index was rarely greater than function reduction in retired workers. Radiographic indices increased with age but only the prevalence of small opacities was significantly related to duration of exposure, total particle years, and asbestos fiber years. Pleural thickening was related only to age. There was evidence of harmful effects of smoking and exposure.
