Dioxins, PCBs and related toxic compounds also in Baltic Sea fish have caused much interest, concern and activity. Dioxins have become a 'boundary object' uniting many disciplines and acting as a symbol also for other concerns and issues. This report, produced in a cooperative project of the Nordic Council of Ministers, synthesizes and evaluates knowledge relevant for assessing and managing risks from dioxin-like compounds in Baltic fish, and analyzes aspects of these risks and their management. It clarifies what risks are associated with 'dioxins' in this context and what can be, ought to be, has been and is being done about them and on what grounds. The intended audiences include experts in the disciplines involved, such as toxicology and chemistry, public health and food safety, and fisheries and environmental management. The report may also be of interest, and is hoped to be of use, to other professionals and students, to decision makers in various realms, even to lay persons, considering the broad and keen interest in the topic field.
