Abstract
Silicosis is well recognized as an occupational disease all over the world. In Ecuador, only a few reports about silicosis have been known, in most cases related to a low number of miners compensated or to some workers in quarries. Two hundred and sixty gold miners heavily exposed to silica dust have been studied with PRODEMINCA (Programa de Desarrollo Minero y Control Ambiental-Ministerio de Energia Minas del Ecuador) support, in four mining areas in the south of Ecuador. Dust was tested to verify SiO, content and total and respirable dust was measured in some spot samples. Miners perform different activities such as drilling, transportation and milling. A standardized questionnaire was used and chest X-ray and lung function tests were performed on all of them. A Prevalence Rate=10.76 of silicosis was reported among this group. Spirometry did not show changes associated with silicosis, although there were sub-groups with FEV1, CV and Tiffeneau indicating obstructive lung diseases. Implementation of preventive measures is suggested to avoid the presence of silicosis among gold miners in Ecuador.
