OSPAR Science Agenda Knowledge Gap Portal

Welcome to the OSPAR Science Agenda knowledge gap portal. The page showcases important scientific questions and evidence needs identified by OSPAR to help protect and sustainably manage the North-East Atlantic. Use the filters and search options below to explore knowledge gaps by topic, category, region, and status, or browse visually to discover areas where new research, data, or collaborations are needed. The aim is to make it easy for anyone - scientists, funders, and policy makers to understand the current priorities, access key details, and get involved in helping to close these important gaps for a healthier ocean future.

Ecotoxicological data voor improving heavy metals assessment criteria
ID Number: H01.01
Knowledge gap description: Lack of ecotoxicological data for developing new assessment criteria based on the EU Water Framework Directive (WFD) or OSPAR Environmental Assessment Criteria (EAC) principles, to replace the current Effects Range-Low (ERL) criteria. Thresholds for trace metals in sediments, fish and shellfish should be developed or updated.

Source of knowledge gap: QSR2023 - Status and Trend for Heavy Metals (Mercury, Cadmium and Lead) in Fish, Shellfish and Sediment
Understanding increasing trends in heavy metal levels in biota
ID Number: H01.02
Knowledge gap description: A better understanding is needed of why concentrations of metals in fish and shellfish are increasing, despite perceived decreasing inputs to the marine environment, and decreasing trends in sediments. Links between metal concentrations and confounding factors like the size of shellfish and fish, the condition of the species analysed, trophic level and dry weight/lipid concentrations should be investigated further.
