title: [The effects of dust inhalation in slate industry workers].
abstract: BACKGROUND
  Slate industries involve the risk of causing silicosis; these industries are now on the increase, which implies an increasing number of workers too. The effects of this type of mining on respiratory health are not yet known.
  
  
  METHODS
  A cross section study of active workers. Radiological and functional alterations, and their relation to risk factors, were assessed.
  
  
  RESULTS
  A prevalence of 2.1% simple pneumoconiosis was found. The value of the FEV1 probed to be significantly related to smoking and to existence of nodulation of a 1/0 or higher profusion; these risk factors, when multiple regression is applied, work independently.
  
  
  CONCLUSIONS
  Slate industry involves a risk of pneumoconiosis and other respiratory alterations.
