A Knowledge Evaluation and Discussion Document

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.

Effects assessment

Elucidation of effects is the crux of risk assessment also for DLCs. Without detailed information on effects risks cannot be adequately identified, estimated and characterized, and their certainty and significance evaluated. Both the biological forms and basis of effects and the rationales used in interpreting them need scrutiny. Assessment of effects is crucial also in evaluating management options. In particular, the information and inference about effects in authoritative risk assessments underlying recent regulatory risk management strategies need to be appraised, taking into account additional information and judgments and modifying the assessments with a view of the Baltic Sea. While an extensive evaluation of the evidence for biological effects of DLCs is beyond the scope of this work, a scrutiny of much of it is essential for the present assessment.
