This is not a comprehensive presentation of all of the findings of this project, but only a brief introduction to project highlights that we feel may be of most interest to those involved in organic chemical exposure assesssment. The project results are, or will be in the near future, documented in more than ten papers in peer-reviewed scientific journals, and more detail can be found in these publications (see pages 11 to 12 for a list). Finally, on the basis of the project results, we have identified five areas, where we think future efforts in bioaccumulation and multimedia fate and transport modelling should be directed (see pages 10 to 11). Achievements The project set out to expand existing multimedia fate and transport models (MFTMs) to include food chain bioaccumulation up to and including humans, and to evaluate their performance. In particular, we wanted to identify what chemical fate situations MFTMs are capable of addressing and for what situations they may not be applicable. We assembled a dynamic human bioaccumulation model (ACC-Human) which includes both the aquatic and agricultural foodchains, and parameterized it for two distinct human populations (Southern Swedes, Arctic Inuit) for which evaluation data could be compiled. In both cases good agreement between
