“…Esta situación, unida a condiciones meteorológicas y climatológicas desfavorables, puede causar impactos negativos sobre la población [32]. En elárea de estudio puede afirmarse que la estabilidad categoría C, favoreció la circulación vertical de la atmósfera, produciendo una mezcla de aire considerable que puede ayudar a la dilución de los contaminantes [5], [8], [9].…”

“…La estabilidad atmosférica de la zona de estudio (clase C, ligeramente inestable) también favoreció la capacidad de la atmósfera para diluir los contaminantes que son descargados sobre ella [48], siendo un fenómeno favorable para los receptores de la zona de estudio, permitiendo mantener bajos niveles de contaminación del aire y ayudando a proteger la salud cardiovascular y respiratoria de la población [9]. Aunque los resultados de la investigación mostraron que no existe un impacto significativo de las emisiones de SO 2 , NO 2 y PST sobre los receptores poblacionales identificados en el estudio, es necesario considerar que en estaárea existen otras industrias y fuentes fijas que podrían contribuir al deterioro de la calidad del aire sobre los receptores estudiados, siendo recomendable realizar una modelización integral que considere todas las emisiones fijas que actualmente afectan la zona de estudio.…”

“…En Europa de han desarrollado más de 120 modelos con diferentes aplicaciones, destacándose algunos paquetes de software como BOOT software, ASTM, AMET, JRC Tool [4], en Estados Unidos se reportan modelos como el HYSPLIT y READY, desarrollados por la National Oceanic and Atmospheric Administration (NOAA), el HPDM desarrollado por el Electric Power Research Institute, PCCOSYMA desarrollado por el National Radiological Protection Board (NRPB) y el Forshungszentrum Karlsruje (FZK) [8], [9], además de los sistemas de modelización recomendados por la Environmental Protection Agency (US-EPA) como AERMOD, CALPUFF, BLP, CALI-NE3 CAL3QHC/CAL3QHCR, CTDMPLUS, y OCD [10]; en Latinoamérica se resalta el software CCATT-BRAMS desarrollado en Brasil [11].…”

“…En Colombia, el marco normativo de calidad de aire regido por el Decreto 948 de 1995 [12] y sus resoluciones reglamentarias 601/2006 [13], 610/2010 [14], 909/2008 [15] y 1541/2013 [16], promueven el uso de los modelos de dispersión AERMOD y CALPUFF avalados por la US-EPA. A nivel mundial se han reportado diferentes estudios relacionados con el uso de AERMOD en la modelización de emisiones de dióxido de azufre (SO 2 ), plomo (Pb), partículas suspendidas totales (PST) y PM10 provenientes de fuentes fijas [5], [9], [17], [18]; en elámbito nacional, se destacan algunos estudios realizados en los departamentos de Boyacá, Cesar y Cundinamarca [19]- [21]. En ciudades como Bogotá D.C., además del uso de AERMOD, se han evaluado otros modelos geoestadísticos y de pluma Gauss para predecir el nivel de contaminación por material particulado (PM10) [22], sistemas difusos evolutivos con resultados satisfactorios, mostrando las redes neuronales como una importante herramienta de predicción [23] y el modelo CCATT-RAMS para estimar el comportamiento de la atmósfera, formación, transporte y remoción de contaminantes en la ciudad y sus alrededores [24], [25].…”

Context: modeling of atmospheric pollutants is an useful tool for air quality monitoring and management. In this study the dispersion of three atmospheric pollutants (SO2, NO2 and Total Suspended Particles - TSP) emitted by a boiler from a paper factory at Valle del Cauca department was estimated and its potential impact on the population settlements located at 5Km around the stationary source was identified.Method: the study was structured in three stages: (i) compiling and processing of meteorological, topographic and isokinetic sampling data; (ii) modeling the dispersion of pollutants using AERMOD ViewTM; and (iii) determination of the impact on surrounding populations.Results: the pollution plume is dispersed towards predominant directions of wind and the trajectory is affected by mountainous topography. The maximum concentrations of pollutants found (0,012 μg SO2/m3, 1,42 μg NO2/m3 and 0,109 μgTSP/m3) were lower than the Colombian air quality standards.Conclusions: the emission-control systems used by the studied paper industry ensures compliance with the air quality standard and generates a low impact on exposed populations. In addition, the atmospheric instability conditions favored the dilution of the contaminants discharged to the atmosphere. Although the AERMOD model was useful in the modeling of pollutants under atmospheric instability conditions and short length (<5 km), it has limitations to simulate the chemical transformations of SO2 and NO2, therefore it is recommended to evaluate other models that allow a comparative analysis and select the most appropriate model.

“…The probabilistic risk assessment (PRA) of potential accidents based on an analysis considering radio active material transport (Rentai 2011) can be performed with an ADM. Studies related to the PRA include a hypothetical accident during the recovery of a Russian submarine (Brown et al 2016), public member dose assessment of an Iranian NPP (Zali et al 2017), and meteorological uncertainty of ADM results (Sørensen et al 2014). A simple PRA for 16 NPPs in Japan was published by the NRA (Nuclear Regulation Agency 2012), but the PRA is not always reasonable for detailed planning including UPZ because meteorological data are sampled from a one-year observation at an NPP site, at which the surface wind is generally different from the flow that determines the advection direction of aerosols.…”

A set of atmospheric dispersion-deposition model (ADM) integrations were conducted with a hypothetical emission of radioactive materials consisting of 137 Cs, 131 I, and 134 Cs from the Tomari Nuclear Power Plant (NPP) in Hokkaido, Japan, which is a snow climate site. Each integration was driven by Japan Meteorological Agency's (JMA's) mesoscale model (MSM) analysis data with 5-km horizontal resolution. The initial conditions were those on each day from January 2010 to December 2016, and the integration period was at most four days. The target was the area within 30 km of the plant. Extending a unit-mass emission concept, the measure of the relative risk is the probability of exceeding the threshold of the maximum effective dose rate based only on exposure from groundshine. Considering that the measure increased monotonically with the ratio of the total emission amount to the threshold, we evaluated the probabilistic risk with its median. The results suggested that the risk was higher in the eastern part of the target area owing to the prevailing westerly flow. The frequent snowfall in winter drags radioactive materials down in the target region, even under an active turbulent condition with strong vertical shear. The composite analysis of wind direction averaged over the target area revealed that the risk was high in the leeside but that mountains effectively blocked the inflow of the radioactive materials. The results were insensitive to wet deposition parameterization. The risk was reduced when we replaced the emission altitude with a higher one than the standard setting. The snow shielding effect was negligible on the short-term radioactivity just after the emission but was substantial on the seasonal change in radioactivity.
