The AMAP Project Directory (AMAP PD) is a catalog of projects and activities that contribute to assessment and monitoring in the Arctic. The Arctic Monitoring and Assessment Programme (AMAP), is a working group under the Arctic Council, tasked with monitoring and asessing pollution, climate change, human health and to provide scientific advice as a basis for policy making.
The directory, which is continously updated, documents national and international projects and programmes that contribute to the overall AMAP programme, and provides information on data access as well as a gateway for the AMAP Thematic Data Centres.

AMAP Core project 2018-2020 is a continuation of previous project which was initiated in 1994. The programme is a monitoring programme of contaminant concentrations in Greenland animals with the objective to follow the temporal trends. The programme includes also screening of contaminants of emergent concerns of selected samples and in some cases retrospective studies of such compounds. Monitoring of temporal trends of effects and biomarkers in samples of polar bears is also included.
Contaminant levels in whales, dolphins, porpoises and seals are measured in blubber, muscle and liver. In addition, diet is studied macroscopically through stomach analyzes as well as through DNA Barcoding analyzes of stomach content, fatty acid analysis in blubber and stable isotope analyses in muscle.
Screening of dechloran plus and new bromminated flame in Greenland biota
Polybrominated diphenyl ethers (PBDEs) are persistent and lipophilic compounds used as flame retardants in electronic equipment, plastic material and synthetic fibbers among other things. The PBDEs are mainly used as Deca-BDE and Bromokal 70-5DE, a mixture of tetra-, penta- and hexa-BDE. Due to its chemical and physical properties PBDEs, especially TeBDEs, tend to bioaccumulate. PBDEs were first reported in sediments in USA, and in fish from a Swedish river. More recently PBDEs have also been reported in seals, birds, mussels, whales and humans. In this study an SFE-method for rapid analysis of PBDEs in marine mammals was developed. This method was used to determinate the concentrations of these environmental pollutants in Pilot Whale samples caught in the Faroe Islands, Beluga Whales from the Arctic and Polar Bears from Svalbard. Using this method several PBDEs were analysed in the different species. In addition methoxylated PBDEs (Me-O-PBDE) were identified by interpretation of the different mass spectra’s. Of the 209 theoretical possible congeners only a few PBDE seem to accumulate in the environment. Accumulation of PBDE is related to the different chemical properties of the molecule. With the help of multivariate characterisation of a compound class using semi-empirical molecular orbital calculations, literature data and actual experimental measurements, the behaviour of PBDE in the environment can be modelled and predicted. Such models are essential in order to gain more insight in the behaviour of PBDE in the environment.
The aim of the project is to develop a method for chemical analysis of brominated flame retardants in marine biota. Furthermore their will be a litterature study of the concentrations of brominated flame retardants in the Arctic.
