Exposure Modeling of Traffic and Wood Combustion Emissions in Northern Sweden

Analysis of Air Pollution in Urban Areas with Airviro Dispersion Model—A Case Study in the City of Sheffield, United Kingdom

“…The Airviro model over-predicted the measured NOx concentrations significantly, which was believed to be due to the constraint that the model did not take into account the photochemical transformation of NOx and ozone. Gidhagen et al [33] employed Airviro model to assess the impact of residential wood combustion on exposure to PM 2.5 and its health impacts in three urbanised areas in Sweden. Gidhagen et al [33] estimated that annual mortality due to modelled PM 2.5 concentrations from residential wood combustion was approximately four people (4 persons/year), corresponding roughly to 0.4% of the total number of deaths in the region.…”

Leksmono et al [29] have reported that distance of the site where meteorological data are collected from the area where pollution is to be modelled is important for assessing the levels of a pollutant, especially for modelling short-term concentrations.…”

“…Esto resulta preocupante ya que los estudios han puesto de manifiesto la variabilidad espacial sustancial en las relaciones entre la exposición a largo plazo a la contaminación del aire exterior y la salud (Singh et al, 2014). Experiencias internacionales indican que en muchas ciudades las concentraciones en masa de MP10 siguen superando los factores de calidad del aire (Cyrys et al, 2014) y que la combustión de madera es una de las fuentes locales dominantes de MP2.5, junto con fuentes como el tráfico de vehículos y emisiones (Gidhagen et al, 2015;Ginzburg et al, 2015).…”
