ABSTRACT

Objective: to identify the association between the exposure of workers to inorganic dust in a quarry and a cement factory and pulmonary diseases.
Methods: a transversal study on data from 32 quarry workers (QWs) and 57 cement production line workers (CFWs) to inorganic-dust exposure was performed. Pulmonary function tests and chest X ray were done in both groups.
Results: there were differences between QWs and the CFWs; QWs were younger, shorter and thinner. The amount of sick individuals might be considered signifi cantly different, showing a smaller proportion on the cement production line. The quarry workers have been on the company for a shorter period of time and, in the end, they present more serious pulmonary problems with an average of 3 years working.
Conclusions: the amount of free-silica that is managed on the quarry affects the workers in some way, even when literature states that the evolution of industrial bronchitis and silicosis have a period development of approximately 10 years.
