Determining NO2 immission levels in a conflicted area: Riobamba, Ecuador

Abstract

Riobamba has areas with high vehicular influence. For the determination of nitrogen dioxide concentrations, passive samplers were used, which were placed at points throughout the domain. The concentrations obtained in the field were interpolated with the information generated with the model traffic emissions software, estimating the relationship between vehicular traffic and the presence of gas. Allow to know the amount of pollutants that breathe about 250 pedestrians on average in the area.
