Abstract |
In order to determine the prevalence of silicosis in the Ivory Coast and its possible repercussions on the respiratory functions, a cross-sectional study was carried out in one of the most important granite quarries of the country. The 126 current workers of the quarry were given a standardized questionnaire and subjected to chest X-ray examinations. Lung functions were tested in 29 non-smoker subjects without anterior thoracic disease. The analysis allowed to identify six cases of silicosis among the 126 workers, corresponding to a prevalence of 4.76%. The affected workers (average age 44) all worked in "crushing", where exposure levels are high. No differences were found in vital capacity between the workers and non-exposed controls selected among the general Ivory Coast population. The prevalence of silicosis appears much lower than that observed in most developing countries. However, the comparison should take into account parameters such as the dust content of free silica and methodologies applied in the definition of silicosis. |
