The main objective of EMEP is to provide governments with information of the deposition and concentration of air pollutants, as well as the quantity and significance of the long-range transmission of air pollutants and their fluxes across boundaries (UNECE, 2004a). The EMEP observations include measurements of species linked to acidification, eutrophication, photochemical oxidants, heavy metals, persistent organic pollutants, and particulate matter.
