41. Environmental assessment of the Isfjorden complex, Svalbard

The project aims to carry out an environmental assessment of the marine environment close to the three main settlements in the Isfjorden complex; Barentsburg, Longyearbyen and Pyramiden. The study comprises analyses of sediment geochemistry and soft-bottom benthic fauna. Attention is given to distinguishing atmospheric transport of contaminants from those arising from local sources.

42. Yukon Traditional Foods Monitoring Program

Short Term i) to provide additional information for use in updating health advisories. Long Term i)to investigate the fate and effects of contaminant deposition and transport to the Yukon, allowing Northerners to better manage the issue of contaminants. ii)to determine levels of contaminants for use in long term trend monitoring.

43. Lead Contamination of Greenland Birds

In Greenland lead exposure to humans from the local diet in general is very low. But the use of lead shot introduces a significant amount of lead in locally hunted birds. Human exposure to lead from the use of lead shot will be assessed by analysing breast meat from thick-billed murre and common eider. In common eider, the Greenland species which is suspected to be most exposed to lead toxicity, the frequency of embedded shots and of shots in the gizzard will be studied, and wing bones will be analysed for lead as an indicator of long-term exposure to lead.

44. Halocarbons in the atmosphere

The objectives are: 1. to monitor in near-real time the levels of a whole suite of halocarbons (both biogenic and anthropogenic) ranging through CFCs, HCFCs, and HFCs using an adsorption/desorption system coupled to a GC/MS system not using liquid cryogens. 2.The system will be installed (April 2000) at the Ny-Alesund, Zeppelin Research Station and will be operated and owned by NILU (Dr. N.SChmidbauer). 3. Comparisons will be made with the data obtained (since Oct. 1994) on similar compounds from the Mace Head (Ireland) station which uses similar instrumentation, and the Jungfraujoch Station (Jan 2000) operated by EMPA (Dr. Stefan Reimann). 4. Data will be compared to the Southern Hemisphere data collected at Cape Grimm, Tasmania by CSIRO (Dr. P. Fraser) 5. Data will be used to model the dispersion of the halocarbons in the high latitudes and possible consequences for radiative forcing.
