In order to assess the effect of silicosis on lung function, 61 gold miners with radiological
silicosis were compared with 61 controls. Each pair was matched for age, dust exposure …

BACKGROUND--In an earlier study of gold miners men with silicosis were found to have
abnormal lung function, including airflow obstruction and reduced diffusing capacity. In a …

In an examination of the relationship between silicosis and lung function, relevant studies of
silica-exposed workers were reviewed. Smoking, dust exposure, and emphysema are three …

Respiratory symptoms, smoking habit, lung function and radiological category of silicosis
were assessed in 276 present and former pottery workers who were receiving industrial …

In a cross-sectional study of a working population of black South African gold miners, 1,197
men were studied with respiratory and occupational questionnaires, lung function tests, and …

Materials and Methods Forty-three men with silicosis in various stages, hospitalized in the

Study objective To reexamine the symptoms, lung function, and chest radiographs of older
gold miners who continued to work in or around gold mines 5 years after their enrollment in …

The relationship between ILO Category for pneumoconiosis, spirometry and four indices of
accumulated dust exposure was studied in the work force of an iron ore surface mining and …

Lung function tests (forced expiratory volume in one second (FEV1), forced vital capacity
