Together with colleagues at Stockholm University, Emma Undeman, researcher at the Baltic Sea Centre, has written four reports compiling the current science on the organic contaminants PCBs, dioxins, brominated flame retardants, PFOS and diclofenac (an active pharmaceutical ingredient). The reports provide description of current knowledge regarding where the substances come from, how they are transported and how the concentrations in the Baltic Sea have changed over time.

HELCOM (Helsinki Commission) has the task of developing a plan for how to further reduce the levels of hazardous substances in the Baltic Sea. In order to implement effective measures, one must know what the most important sources are and which route the chemicals take to the sea. The reports will contribute to HELCOM's work in this field.

 –We must identify the major sources of the hazardous substances and understand how they move in the ecosystems to be able to do something about the problem, says Emma Undeman.
