Publicación Acceso abierto Determinación del SARS-CoV-2 en material particulado mediante método analítico por espectrofotometría ultravioleta visible (UV-VISIBLE): una revisión(2021-10-12) Montiel Murillo, Senis Beatríz; Paternina Uribe, Roberth de JesúsThe coronavirus disease outbreak was first reported in Wuhan, China in late 2019 and early 2020. SARS-CoV-2 is a single-stranded RNA virus, the main cause of a serious respiratory disease called COVID-19, which is the cause of the current pandemic and which has spread rapidly in the human population. This review brings together the most relevant studies, carried out to date worldwide, which focus on knowing whether air pollution, especially particulate matter (PM2.5 and PM10), is considered a propitious transport agent for the virus, having taking into account that PM is identified as the main environmental cause of disease and premature death in the world, since it has a toxicity capacity that can increase by being able to absorb other substances such as polycyclic aromatic hydrocarbons (PAH), its heavy metals so that pathogens as long as they are below the radius of its diameter. Factor that affects the body's immunity, which makes people more vulnerable to contagions, therefore, it is important and crucial to elucidate the role of air pollution particles in the spread of the virus through a technique that is fast, accurate, versatile, easy to use and cost efficient like UV-visible spectroscopy. The method used to carry out this monograph was through a search, collection and bibliographic review of articles and scientific studies, graduate work, books, publications in scientific journals. Finding that there is a positive association between exposure to particulate matter and the presence of the virus. In addition, numerous studies highlight the potential links between exposure to air pollution and the severity of COVID-19, but there are very few investigative reports on the fast, accurate and economically viable diagnostic method such as UV-visible spectroscopy. Finally, according to the research carried out to date, they emphasize the importance of scientific studies to elucidate the role of air pollution particles in the spread of the virus and the performance of a technique for the sensitive and accurate detection of SARS-CoV viruses. -2 in the air.Publicación Acceso abierto Medición y análisis de material particulado en el área de colocación de concreto de la Empresa soluciones de ingeniería nomadas S.A.S del Municipio de Cerete(2021-07-11) Monterroza Percy, Daniela Maria; Bedoya Ortiz, Jesús Mario; Guerrero Yepes, Stephanie; Ochoa Guerra, Jairo DanielEl presente trabajo de grado presentado, en la modalidad de Trabajo de Aplicación tiene como objetivo evaluar la concentración de material particulado en el área de colocación de concreto en sitio de obra de la empresa Soluciones de Ingeniería Nómadas S.A.S. Para evaluar la concentración de material particulado se escogió la técnica de análisis muestreo UNE 81599 "Método para la determinación de material particulado (partes inhalables y respirables) en el aire", lo anterior, con el fin de medir los riesgos ocasionados por la exposición al material, y establecer las medidas necesarias para reducir su impacto en la salud de los trabajadores expuestos, a fin de evitar la ocurrencia de enfermedades ocupacionales. Por medio de la técnica de muestreo UNE 81599 se obtuvo como resultado que en el área de colocación de concreto se encuentra una concentración de 8,2335329. Esta información se detalla con mayor precisión en las conclusiones emitidas en el inciso N°7.1 de este trabajo.
