Development of a monitoring and assessment concept for the pollution load of marine mammals of the North Sea and Baltic Sea for the implementation of the MSFD.

Project description

The aim of the project is to develop a monitoring and assessment concept for the pollutant load of marine mammals in the North and Baltic Seas. The work thus also contributes to the implementation of the requirements for descriptor 8 (pollutants) of the Marine Strategy Framework Directive (MSFD).
Within the scope of the contract, the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) of the University of Veterinary Medicine Hannover (TiHo) Foundation will evaluate the current state of knowledge on pollutant loads and health effects for harbor porpoise (Phocoena phocoena), grey seal (Halichoerus grypus) and harbor seal (Phoca vitulina) from the North and Baltic Seas using existing publications, reports and data sets. For this purpose, studies from the North Sea and the Baltic Sea as well as from other marine areas will be used. Furthermore, a monitoring and assessment concept for the pollution load of marine mammals under the MSFD, the Convention for the Protection of the Marine Environment of the Baltic Sea (HELCOM) and the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) will be developed. The utilization of the determined pollutant data in marine mammals for the chemical legislation, e.g. REACH, Plant Protection Act will be ensured together with UBA.
In order to be able to assess the pollutant load, assessment thresholds for selected pollutants for the protection of marine mammals will be developed together with the Helmholtz Centre for Environmental Research GmbH (UFZ): environmental quality standards (EQS) will be derived for the selected pollutants, following the methodology of the EU Technical Guidance Document (TGD) No. 27, in order to comply with the Water Framework Directive (WFD), the MSFD and the regional conventions OSPAR as well as HELCOM in approach and level of protection. The aim is that the marine mammal EQS to be developed will support the implementation of descriptor 8 (pollutants) and indicator development at OSPAR as well as HELCOM for a (regional) assessment of marine mammal pollutant loads.
