Description
El monitoreo atmosférico es una de las etapas fundamentales en la identificación de estrategias para minimizar, prevenir y controlar los impactos de la dispersión de contaminantes en el aire, sobre la salud pública y el ambiente. Por tanto, el objetivo principal de este articulo consiste en proponer una metodología para la selección de sitios de monitoreo atmosférico en zonas urbanas afectadas por las emisiones de fuentes móviles. Primeramente se identificaron los sitios que presentaban mayor flujo vehicular y se priorizaron teniendo presente los siguientes criterios de selección: seguridad, influencia de otras fuentes, facilidad del montaje de los equipos, accesibilidad al sitio, identificación de barreras y obstáculos, registro histórico de datos y grado de concentración usando el software CALINE 3.La modelación agrupo datos característicos de las vías, meteorológicos y de flujo vehicular de un año típico de la zona en estudio. A cada uno de estos parámetros le es asignada una valoración cuantitativa, la cual define los sitios donde se realizará el monitoreo. Como resultados se desarrolló una guía para seleccionar los lugares en donde se puedan desarrollar campañas de monitoreo atmosférico asociadas a fuentes móviles. La metodología fue aplicada en la ciudad de Cartagena de Indias haciendo uso del modelo de calidad del aire CALINE3.
Atmospheric monitoring is one of the fundamental steps in identifying strategies to minimize, prevent and control the impact of the dispersion of pollutants in the air, on public health and the environment. Therefore, the main objective of this article is to propose a methodology for selecting air monitoring sites in urban areas affected by emissions from mobile sources. First, the places with the highest vehicular flow were identified and prioritized according to the following selection criteria: safety, influence of other sources, ease of assembly of equipment, accessibility to the site, identification of barriers and obstacles, historical record of data and degree concentration of the pollutant: in this case carbon monoxide, using CALINE 3 software. The modeling grouped characteristic data related with roads, meteorology and vehicular flow of a typical year of the zone under study. A quantitative assessment is assigned to each of these parameters, which defines the sites where the monitoring will be performed. As a result, it was developed a guide to select those places where atmospheric monitoring campaigns related with mobile sources can be held. This methodology was applied in the city of Cartagena de Indias by using air quality model for assessment, CALINE 3
