Evaluación de la exposición a solventes orgánicos en pintores de carros de la ciudad de Bogotá
Palma, Ruth Marien
Introduction. The painters of motor vehicles are exposed to pure solvents or mixtures thereof, which have been associated with neurological and mutacarcinogénicos effects. Materials and Methods. A descriptive cross-sectional study was conducted to characterize the health and working conditions of individuals exposed to organic solvents in film and painting workshops in Bogotá. Group exposed to organic solvents with non-exposed group were compared. Concentrations of benzene , toluene and xylene (BTX ) in air is determined, an individual survey is applied and measured in urine, phenyl mercapturic acid, hippuric acid, ortho-para metabolites methylenechippuric as benzene, toluene and xylene . The results of the measurements and survey were correlated to establish the exposure scenario. Results: There were statistically significant differences between the exposed population and the population not exposed to solvents (p = 0.00) for the three 3 metabolites of BTX. Positive correlations among the toluene in air and hippuric acid in the urine of the subject is found, (Spearman 0.82) and between the air and xylene or methylhippuric acid (0.76 Spearman). Hippuric acid values were found above the permissible limits in 11 workers and p- methylhippuric acid in 8 of them. There were no values for acid phenylmercapturic off limits. Discussion: car painters are exposed to high levels of organic solvents in their workplace and do not have adequate conditions of hygiene and safety to do their jobs.
