AMAP Project Directory

AMAP Project Directory

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.

Other catalogs through this service are ENVINET, SAON and SEARCH, or refer to the full list of projects/activities.

1. Spatial trends and pathways of POPs and metals in fish, shellfish and marine mammals of northern Labrador and Nunavik

The objectives of this study were to develop baseline data on persistent organic pollutants (POPs) and metals, in freshwater and anadromous fish, shellfish, and marine mammals, important to Inuit communities of Northern Labrador and Nunavik in order to provide the same level of information that is available for other Canadian arctic regions. 1999-00 was the final year of the project. Successful collection of mussels (Mytilus edulis), arctic char (sea run), scallops and walrus samples were made in 1999. During 1998 major collections of ringed seal, sea run arctic char and blube mussels (Mytilus edulis) were made. Chemical analyses of POPs and metals in ringed seals and char collected in 1998-99 were completed in 1999-2000. Low concentrations of mercury, selenium and lead were found in samples of scallops from Labrador while cadmium and arsenic levels were much higher than the other elements, especially in gut samples. Arsenic was the most prominent of the five metals determined in mussels from Nunavik. Mercury levels were low (0.02-0.03 ug/g wet wt) in char from Labrador collected in 1999 similar to our previous observations in Labrador and Nunavik. Much higher levels of mercury and selenium were found in landlocked char (at Kangiqsujuaq) and than in all sea run char from widely separated sites Nunavik and Labrador. Mercury and selenium levels in seal liver did not differ among the 5 locations after adjustment for age of the animals. Percent organic mercury levels increased with age in seal muscle from about 80% in animals from 0-2 yrs to about 100% in adult animals. Mercury levels in walrus meat (muscle) were relatively low compared with liver and kidney. Levels of tributyl tin in char muscle ranged from <0.01 to 0.85 ng/g wet wt and highest levels were found in samples from Kangirsuk (Ungava Bay region). PCBs and other organochlorines were present at very low levels in mussels and arctic char from locations in Nunavik and Labrador. In general, levels of PCBs and SDDT in ringed seal blubber in this study were similar to levels found in ringed seal blubber at other eastern Arctic locations.

2. Temporal trends of persistent organic pollutants and metals in ringed seals from the Canadian Arctic

The objective of this project is to study long term temporal trends of persistent organic pollutants and mercury in ringed seals from the Canadian arctic. The project rationale is that there are previous results for POPs and mercury in ringed seal tissues for many locations. Furthermore there may be regional differences in temporal trends due to geographical differences in POPs and mercury in marine waters and food webs within the Canadian arctic. It is relatively cost efficient to return to the same locations for additional samples using the same sampling and anlaysis protocols are were used in previous studies (see AMAP and Canadian Assessment Reports). Samples are being collected with the help of hunters and trappers organizations in each community. During 2000-01 samples are being collected at Resolute, Arctic Bay and Pond Inlet. The study will also analyse samples collected recently (1998/99) from Pangnirtung, Arviat and Grise Fiord. Results will be compared with previous data which the Principal Investigator generated in the 1980's and early 1990's. Preliminary results will be available in mid-2001.
