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.

21. Effects and Trends of POPs on Polar Bears

LONG TERM: Determine the effects, at the individual and population level, of persistent organic pollutants (POPs) and their metabolites in the polar bear; determine trend of POPs in the Arctic marine environment using polar bear tissues as a biomonitor. SHORT TERM: a. Determine 10-year temporal trends of POPs in the Hudson Bay Sub-Arctic Ecosystem from 1990-1989 by analysis of archived polar bear biopsy samples, including changes in enantiomeric composition of -HCH and chlordane compounds and ratio of -HCH/-HCH (cross-referenced to separate proposal on HCHs). b. Determine if there is selective tissue distribution of the enantiomers of chiral contaminants in polar bears, which may influence target organ toxicity, by analysis of archived polar bear samples. c. Determine the endocrine disrupting effect of POPs on testosterone and PCB metabolite profiles by in vitro metabolism studies using polar bear liver microsomes. d. In collaboration with CWS P&N Region, the Norwegian Polar Institute and the Norwegian Veterinary Institute, determine the immunotoxic effects of PCBs and other organochlorines in polar bears throughout a gradient of exposure (Hudson Bay, low; Svalbard, high). e. Determine the effects of hydroxy-PCBs on circulating thyroid hormone and vitamin A concentrations.

22. Monitoring and Modelling of Atmospheric Pollution in Greenland

In 2000 it is proposed to operate an atmospheric programme consisting of a monitoring and a modelling part and composed of 3 programme modules. The monitoring programme consists of two parts. I. It is proposed to continue the weekly measurements of acidifying components and heavy metals at Station Nord in north-east Greenland for assessment of atmospheric levels and trends. The measuring programme includes also highly time resolved measurements of Ozone and of total gaseous Mercury (TGM). The results will also be used for continued development and verification of the transport model calculations. Receptor modelling of the pollution composition will be used for identification and quantification of the source types that influence the atmospheric pollution in north-east Greenland. Comparison of the two sets of modelling results is expected to give better models. II. The purpose of the project is the operation of a permanent air monitoring programme in the populated West Greenland at a location which is representative for transboundary air pollution. The most promising sites are located in the Disko Bay area and in the vicinity of Nuuk. The objectives are to obtain data on the concentration levels of air pollutants that can be used for assessing seasonal variations and trends and for studying long range transport of pollutants mainly from North America to West Greenland. The purpose is further to provide data for development and improvement of long range transport models that can be used to identify the origin of the pollution and its transport pathways. The results from measurements and model calculations will be used to assess the magnitude of deposition to sea and land in this populated region of Greenland. III. In the proposed modelling programme the operation, application and maintenance of the current basic hemispheric model will be continued. Results on origin, transport, and deposition of contaminants on land and sea surfaces in the Arctic are essential for interpretation and understanding the Arctic air pollution. The model will be developed to improve the spatial and temporal resolutions, as well as the accuracy by including physically and mathematically better descriptions of the key processes treated in the model. The work to expand the model to include also non-volatile heavy metals, such as Cadmium and Lead on an hemispheric scale will be continued. Since the atmospheric chemistry of Ozone and Mercury seem to be strongly connected in the Arctic it is planned to continue the development and testing of a model module for hemispheric transport and chemistry for ozone and mercury to assess the origin and fate of this highly toxic metal in the Arctic.

23. New Persistent Chemicals in the Arctic Environment

The objectives of this project are A) to determine coplanar polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), brominated diphenyl ethers (BDPEs), chlorophenolic compounds and chloroparaffins in air from arctic monitoring stations; and B) to search for other "new" chemicals in the arctic environment, not currently monitored by Canada's Northern Contaminants Program (NCP) but of potential concern based on known persistence, extent of usage and toxicology.

24. Global Gridded gamma-HCH and Endosulfan Emission Inventories

The aim of this project is to compile information and create a computerized database of historical and present global lindane and endosulfan usage data as well as emission data for gamma-hexachlorocyclohexane (gamma-HCH) and endosulfan with 1 degree x 1 degree lat/long resolution. The objectives of this project are: A) to create global gridded g-HCH and endosulfan emission inventories; B) to study the linkage between global g-HCH and endosulfan use trends and g-HCH and endosulfan concentration trends in the Arctic; and C) to assist in comparing concentrations and ratios of different HCH isomers in the Arctic biotic and abiotic environments.
