State of the art and research needs for the impact category eutrophication are discussed. Eutrophication is a difficult impact category because it includes emissions to both air and water -both subject to different environmental mechanisms -as well as impacts occurring in different types of terrestrial and aquatic ecosystems. The possible fate processes are complex and include transportation between different ecosystems. In some recent approaches, transportation modelling of air emissions has been included. However, in general, the used characterisation methods do not integrate fate modelling, which is a limitation. The definition of the impact indicator needs further research, too. The inclusion of other nutrients than those typically considered should also be investigated. | | Keywords: air emissions; aquatic systems; biomass production; ecosystems; eutrophication; fate modelling; impact category; nitrogen; nutrients; phosphorous; terrestrial systems; transportation; water emissions |
