The accumulation of contaminants in the environment is affected by several natural and anthropogenic factors and the interactions between these. In particular, the potential impact of climate change on contaminant levels have attained a lot of attention in the last decade. But the implications of “multi-stressor pressures”, i.e. the combined impact of several factors such as future climate change, land use and eutrophication, for chemicals management have not been evaluated. In this project I will develop and use existing models to create a spatially and temporally resolved contaminant watershed model that calculates contaminant loadings from the entire Baltic Sea catchment. This watershed model will then be coupled to a model for the marine Baltic Sea environment in order to assess how the transport and ultimate fate of organic contaminants in the Baltic Sea environment are influenced by future changes in environmental conditions. Also the applicability of the model for evaluating emission reduction measures in a multi-stressor environment will be evaluated by performing case studies for two groups of chemicals.
