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. Concentrations and patterns of persistent organochlorine contaminants in beluga whale blubber.

White whale (Delphinapterus leucas) blubber samples from three of the five different Alaskan stocks - Cook Inlet (n = 20), Eastern Chukchi Sea (n = 19) and Eastern Beaufort Sea (n = 2) - were analyzed for levels and patterns of chemical contaminants. Blubber of these whales contained sum PCBs, sum DDTs, sum chlordanes, HCB, dieldrin, mirex, *toxaphene and *HCH, generally in concentration ranges similar to those found in white whales from the Canadian Arctic and lower than those in white whales from the highly contaminated St. Lawrence River. The males of the Cook Inlet and Eastern Chukchi Sea stocks had higher mean concentrations of all contaminant groups than did the females of the same stock, a result attributable to the transfer of these organochlorine contaminants (OCs) from the mother to the calf during pregnancy and during lactation following birth. Principal components analysis of patterns of contaminants present in blubber showed that Cook Inlet stock appeared to have identifiable contaminant patterns that allowed the stock to be distinguished from the others. Our results also showed that blubber from the three Alaskan stocks was a source of contaminant exposure for human subsistence consumers, but the health risks from consumption are currently unknown.
