title: [Lung function in children residentially exposed to asbestos].
abstract: Impairment of respiratory function is one of the most sensitive indicators used in the evaluation of the effects of air pollution on human health. We compared predicted values of flow-volume curve according to Knudson and the spirometry results in 81 healthy children; 40 girls and 41 boy, aged (10.69 +/- 2.24) years. We also measured the transfer factor of the lungs for carbon monoxide (TLCO) using the single-breath method and compared the results with reference values by Cotes. Patients were selected randomly among pre-school and elementary school children from the Split area, who were residentially exposed to asbestos. Children with atopic diseases, family history of atopy, history of severe respiratory diseases, and history of smoking were excluded from study. We found a statistically significant difference in FVC (p < 0.0001) from normal values according to Knudson, but when expressed in the percentage of the Knudson values, this difference was not significant (p > 0.05). No statistically significant difference was found for FEV1, FEF75, FEF50, FEF25, and FEV1/FVC. TLCO reached (107.37 +/- 20.50)% of normal values according to Cotes, and was not significantly different. At this point, it is hard to predict the consequences of exposure to low levels of asbestos in childhood, because it takes a long time for complications such as neoplasms, pulmonary fibrosis, or respiratory insufficiency to develop.
