JEG DM: progress in DM

dynamic models became a commonly used tool, several ICPs and national focal points use DM DM provide timescale to expected changes there is a variety of models used looking into soils, waters and changes in plant species, site specific and regional impact on policy is still questionable, unclear why

several models in use and under tests and development observed changes are slow (decades at least), time series of observations are scarce evaluation of models is problematic

dynamic models do have ability to make robust predictions of chemical status and to an extent even of impact on organisms models have been tested and provide policy- relevant outputs (e.g. target loads) challenge remains to make an impact on policy
