Exposición a benceno, xileno, tolueno y efectos en la función hepática en trabajadores de estaciones de servicio de combustible de Esmeraldas en Petroecuador

Abstract

Summary: Objectives: To analyze the association between exposure to volatile organic compounds and hepatoxicity in workers at Petroecuador service stations in Esmeraldas. Method: Analytical study, based on a sample of 38 workers from Service Stations, comprising 22 workers exposed and 16 workers not exposed to volatile organic compounds in the period 2015 to 2020, the data will be collected through occupational medical records. The correlation between the level of exposure and the effects on liver functions will be measured through measures of association. Results: To know the description of the sociodemographic characteristics (age, sex, level of education and toxic habits) in addition to showing that the workers exposed to Covs (benzene, toluene, xylene) in the Petroecuador Service Stations in Esmeraldas, present alterations of liver function in relation to unexposed workers. Implications: Present significant contributions in the field of occupational health and safety through relevant information on liver damage due to exposure to Covs, statistical bases will be provided to propose prevention plans aimed at avoiding occupational diseases and achieving timely treatment of those affected. Limitations: The socioeconomic, work and employment conditions, in addition to the small size of the population and incomplete medical records, which makes it impossible to adequately collect the data. Strengths: The research will show the association of liver involvement and exposure to Covs at the local level, allowing decision-making and generation of epidemiological toxic surveillance plans.
