Exploratory Study on Occupational Health Exposure to Chemical Agents, in a Public Hospital in Valencia, Venezuela. Preliminar Assessment

Descriptive study that identified chemical agents (AQ) use and training on risk management and waste disposal techniques in a public Hospital in Valencia. A questionnaire was answered by 48 workers. Information obtained was: personal data, occupational history, AQ used; knowledge of risk management and waste disposal. There were 16 occupations from 12 “High Risk” areas. “Adult emergency” was the one with more workers (11 individuals), followed by “sterilization” and “clinical laboratory” (7 each) and oncology (5). The remained areas had less than 8.3% workers. The most used anesthetic agents were: Halothane, Enfluorane and Isofluorane 4.17% each and main antineoplastics used were: Doxorubicin 16.67% and Paclitaxel, 5-Fluoracil and Etoposide, 8.33% each. The most mentioned substances were: alcohol (70.8%) and Chlorine (64.6%). None of the answers regarding knowledge of AQ’ risk management and waste disposal was satisfactory. Statistical associations between training and several variables such as age, time in their job and being or not a professional, resulted non-significant. The correlation between training and the knowledge of AQ’s management was significant (p < 0.001). Participants showed that their knowledge about chemical occupational risk factors they are exposed to is still insufficient. Therefore, this theme should be included in graduate course curricula. These results provide important data and will serve as a pilot research for the follow up Phase II study that will include clinical aspects and environmental and biological monitoring.

Niveles de exposición a fungicidas ditiocarbamatos y su relación con las condiciones de trabajo en el sector floricultor en la Sabana de Bogotá D.C. (Cundinamarca) y Rionegro (Antioquia), Colombia, durante el año 2011

El interés del estudio de investigación se basó en recolectar datos de exposición ocupacional a plaguicidas ditiocarbamatos en el sector floricultor. Objetivo: Determinar los niveles de exposición a fungicidas ditiocarbamatos y su relación con las condiciones laborales de los trabajadores del sector floricultor en la Sabana de Bogotá D.C. (Cundinamarca) y Rionegro (Antioquia), Colombia, durante el año 2011. Materiales y Métodos: Se realizó un estudio de corte transversal, en 358 trabajadores de un total de 3700 empleados de 27 empresas del sector floricultor, 12 ubicadas en la Sabana de Bogotá (Cundinamarca) y 3 en Rionegro (Antioquia). Se recoleto información sobre condiciones de trabajo y antecedentes de exposición de la población y se determinaron los niveles de exposición a fungicidas ditiocarbamatos en muestra en orina mediante método Montesano. Conclusiones: Este estudio describe la forma como se utilizan y los niveles de exposición a fungicidas ditiocarbamatos ETU, en el sector floricultor en Colombia. Se dan recomendaciones para mejorar los tiempos de re-ingreso al cultivo según la categoría toxicológica de los productos.
