Asociación entre la exposición a asfalto y efectos en la salud en los trabajadores de laboratorio de control de calidad de una empresa constructora de infraestructuras viales del Ecuador

Abstract

Objectives: To analyze the relationship between exposure to asphalt and the possible acute and chronic harmful effects on the health of exposed personnel through occupational medical examination, the application of diagnostic tests and biological monitoring. Simultaneously, the types of harmful effects on the health of exposed workers will be evaluated; and finally, the organs or systems most affected by the exposed workers will be identified. Method: A descriptive, cross-sectional and observational study was designed, where a group of 6 workers who have performed specific activities of asphalt quality analysis in a period of at least two years will be evaluated by means of: clinical interviews, medical examinations, analysis of 1-hydroxypyrene, by administering symptomatology questionnaires (Nordic dermal occupational questionnaire and respiratory symptoms questionnaire ATS 78); and field visits. Results: We expect to find a high prevalence of acute and chronic irritative symptoms in the respiratory and dermal systems, which will be associated simultaneously with an increase in the urinary biomarker 1-hydroxypyrene. Implications: The present study will support the evaluation of the consequences of acute and chronic asphaltic exposure in an under-studied occupational group, providing very useful information for preventionists working in similar companies and giving rise to new studies or research of this type.
