Abstract:Ambient air pollution causes serious human health problems. Geostatistical interpolation methods have proven to efficiently estimate exposure to air pollutants. In this study, we employed Ordinary Kriging to predict PM2.5 concentrations due to woodsmoke in the conurbation of Temuco and Padre Las Casas, Chile using mobile measurements conducted during June and July of 2016. Overall, the results suggest that higher PM2.5 concentrations were estimated in Temuco. Spatial differences in high PM2.5 concentrations are observed when examining the PM2.5 estimates by month. The results of this study may help authorities and policymakers to implement environmental actions to reduce air pollution in the studied conurbation.
