DOI: 10.1016/j.atmosenv.2017.10.017

Abstract: Abstract While land use regression models (LUR) are commonly used, e.g. for the prediction of spatially variable air pollutant mass concentrations, they are scarcely used for predicting the oxidative potential (OP), a suggested unifying predictor… read more here.

DOI: 10.1016/j.envpol.2017.06.051

Abstract: Particulate air pollution being recognized to be responsible for short and long term health effects, regulations for particulate matter with an aerodynamic diameter less than 2.5 (PM2.5) are more and more restrictive. PM2.5 regulation is… read more here.
