description La contaminación atmosférica por material particulado PM2.5 es una de las mayores preocupaciones a nivel mundial debido a sus impactos negativos en el medio ambiente y en la salud de los seres vivos, como el aumento de la mortalidad. Estas partículas contienen contaminantes co-emitidos entre los que se incluyen los Hidrocarburos Aromáticos Policíclicos (HAPs), que tienen propiedades toxicológicas como toxicidad, cáncer, neurotoxicidad, citotoxicidad y disrupción endocrina. En la ciudad de Barranquilla se han investigado los contaminantes atmosféricos entre ellos el PM2.5, el cual es un tema que se ha desarrollado con distintos estudios, aún no se reportan estudios relacionados sobre los HAPs en el material particulado de la ciudad, donde se presume la presencia de estos porque la ciudad es una zona densamente poblada, industrializada y que tiene antecedentes con la contaminación atmosférica. Mediante esta investigación fue posible cimentar una línea base sobre los HAPs en el aire de la zona de estudio, muestreando en 2 puntos de la zona urbana de Barranquilla, el primero (Universidad de la Costa) en zona residencial y el segundo (Escuela de Policía Antonio Nariño) cerca de una carretera regional principal que está influenciada por fuentes como tráfico vehicular y emisiones industriales de la ciudad. Se utilizó un muestreador de medio volumen para recolección de PM2.5 con un intervalo de medición de 48h durante febrero y marzo de 2020, así como agosto, octubre, y noviembre de 2021. Entonces las concentraciones de PM2.5 oscilaron entre 7,94 y 33,90μg.m-3 mientas que el promedio HAPs totales fue de 0,0171ng.m-3 , entre los cuales el Benzo[a]pireno (BaP) presentó la mayor concentración con 0,1162ng.m-3 , algunos estudios concuerdan que el control y prevención de los efectos es posible mediante el diagnostico de contaminantes atmosféricos. Por su presencia existen riesgos a la población de la ciudad especialmente para las más vulnerables.

Estas partículas contienen contaminantes co-emitidos entre los que se incluyen los Hidrocarburos Aromáticos Policíclicos (HAPs), que tienen propiedades toxicológicas como toxicidad, cáncer, neurotoxicidad, citotoxicidad y disrupción endocrina. En la ciudad de Barranquilla se han investigado los contaminantes atmosféricos entre ellos el PM2.5, el cual es un tema que se ha desarrollado con distintos estudios, aún no se reportan estudios relacionados sobre los HAPs en el material particulado de la ciudad, donde se presume la presencia de estos porque la ciudad es una zona densamente poblada, industrializada y que tiene antecedentes con la contaminación atmosférica. Mediante esta investigación fue posible cimentar una línea base sobre los HAPs en el aire de la zona de estudio, muestreando en 2 puntos de la zona urbana de Barranquilla, el primero (Universidad de la Costa) en zona residencial y el segundo (Escuela de Policía Antonio Nariño) cerca de una carretera regional principal que está influenciada por fuentes como tráfico vehicular y emisiones industriales de la ciudad. Se utilizó un muestreador de medio volumen para recolección de PM2.5 con un intervalo de medición de 48h durante febrero y marzo de 2020, así como agosto, octubre, y noviembre de 2021. Entonces las concentraciones de PM2.5 oscilaron entre 7,94 y 33,90μg.m-3 mientas que el promedio HAPs totales fue de 0,0171ng.m-3 , entre los cuales el Benzo[a]pireno (BaP) presentó la mayor concentración con 0,1162ng.m-3 , algunos estudios concuerdan que el control y prevención de los efectos es posible mediante el diagnostico de contaminantes atmosféricos. Por su presencia existen riesgos a la población de la ciudad especialmente para las más vulnerables.Atmospheric pollution by particle matter PM2.5 is one of the majors worldwide concerns due its negative impacts on the environment and in living beings’ health, such as mortality increase. These particles contain co-emitted pollutants such as Polycyclic Aromatic Hydrocarbons (PAHs), which has toxicologic properties such as toxicity, cancerogenic, neurotoxicity, cytotoxicity, and endocrine disruption. In Barranquilla city atmospheric pollutants have been studied within them PM2.5, which is a topic that has developed with different studies, regardless related studies about PAHs in particular matter of the city have not yet been reported, where the is supposed the presence of them due is a densely populated, industrialized area and that had dealing with issues such as atmospheric pollution. Through this investigation was possible to concrete a base about the state of the PAHs in the air of the study area, sampling in 2 points in Barranquilla’s urban zone, the first (Universidad de la Costa) in a residential area and the second (Escuela de Policia Antonio Nariño) near a main regional highway that is influenced by sources such as vehicular traffic and industrial emissions of the city. A medium volume sampler was used for the collection of PM2.5 with a measure range of 48h during February and May 2020, such as August, October, and November 2021. Then PM2.5 ranged among 7,94 and 33,90μg.m-3 while the total PAHs mean was de 0, 0171ng.m3 , which Benzo[a]pyrene (BaP) presented the highest concentration with 0,1162ng.m-3 , some studies agree that control and prevention of the effects is possible by the diagnosis of atmospheric pollutants. Due to its presence, there are health risks to the population of the city especially the most vulnerable ones.Lista de Tablas y Figuras 9 -- Introducción 13 -- Planteamiento del Problema 16 -- Justificación 20 -- Objetivos 23 -- General 23 – Específicos 23 -- Marco Teórico 24 -- Material Particulado 24 -- Variación espaciotemporal del material particulado 26 -- Hidrocarburos Aromáticos Policíclicos (HAPs) 26 -- Fuentes de Hidrocarburos Aromáticos Policíclicos 30 -- Volatilización de los HAPs 32 -- Solubilidad (coeficiente carbono orgánico / Coeficiente octanol-agua) 34 -- Reactividad de los HAPs 35 -- Dinámica Ambiental de los HAPs 36 -- Toxicidad de los HAPs 38 -- Colección del Material Particulado 40 -- Metodologías de Extracción de HAPs 41 -- Extracción Soxhlet 41 -- Extracción por Microondas (MAE) 42 -- Extracción acelerada con disolventes (ASE) 43 -- Extracción QuEChERS 43 -- Micro-extracción de fase solida (SPME 44 -- Extracción asistida por ultrasonido (USE) 45 -- Extracción con fluidos supercríticos (SFE) 45 -- Fluido Super crítico y Cromatografía (SFE-GC) 46 -- Extracción con disolventes acelerada (ASE) y Cromatografía de líquidos de alta eficiencia (HPLC) 46 -- Metodologías de identificación y cuantificación de HAPs en Material Particulado 47 -- Cromatografía de gases acoplada a espectrometría de masas (GS-MS) 47 -- Cromatografía de líquidos de alta eficiencia (HPLC) con detección por Fluorescencia (HPLC-FD) 50 -- Cromatografía de líquidos de alta eficiencia con Espectrofotometría Ultravioleta (HPLC-UV)......51 -- Estado del Arte 53 -- Estudios a nivel Internacional 53 -- Estudios a nivel Nacional 62 -- Estudios a nivel Regional y Local 63 -- Metodología 66 -- Área de Estudio 66 -- Estaciones de Muestreo 67 -- Muestreo de Material Particulado 68 -- Metodología de Extracción 72 -- Cuantificación de Hidrocarburos Aromáticos Policíclicos 72 -- Cromatografía de gases acoplado a masas 72 -- Análisis y discusión de resultados 74 -- Identificación de efectos toxicológicos 76 – Resultados 78 -- Concentraciones de Material Particulado PM2.5 78 -- Concentraciones de HAPs 79 -- Variables Meteorológicas y su relación en las concentraciones de PM2.5 y HAPs 86 -- Rosa de los Vientos 86 -- Correlación estadística HAPs-PM2.5 96 -- Prueba de Normalidad 97 -- Correlación Rho-Spearman 99 -- Parámetros de Toxicidad de HAPs 101 -- Comparación con otros estudios 111 -- Comparación estudios Nacionales 115 – Conclusiones 118 -- Recomendaciones 119 – Referencias 121 --Ingeniero(a) CivilPregrado156 páginasapplication/pdfspaCorporación Universidad de la CostaCivil y AmbientalBarranquilla, ColombiaIngeniería CivilDeterminación de los hidrocarburos aromáticos policíclicos en pm2.5 de la zona urbana de Barranquilla, AtlánticoTrabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1fTextinfo:eu-repo/semantics/bachelorThesishttp://purl.org/redcol/resource_type/TPinfo:eu-repo/semantics/acceptedVersionBarranquillaAtlánticoAbbas, I., Badran, G., Verdin, A., Ledoux, F., Roumié, M., Courcot, D., & Garçon, G.
